Hartzell Model Explanation
How To Use Model Code Index:
Example – Assume a needed performance of 8,400 CFM at 0" S.P.W.G. at standard conditions is required for an exhaust application. Reading the
rating table on page five; a 24", series 61, direct drive upblast roof ventilator operating at 8380 CFM at 0" SP. It is also determined from the rating table
the ventilator will consist of the following: standard construction, 1140 RPM totally enclosed air over motor, and a three blade lo-noise propeller. Knowing
this the model code can be constructed as follows: the fan is a direct drive upblast roof ventilator, therefore, the series is “61”, “G” (General Industrial)
Duty construction; the size is “24”; the propeller is a lo-noise, therefore, blade is “L”; the construction is standard, therefore, material is “ST”, the motor
is a totally enclosed air over, therefore, the enclosure is “AO”, the horsepower required is .68 BHP, therefore, the horsepower code is “G”, and the motor
RPM is 1140, therefore, the RPM code is “4”.
Note: 1) All other informational fields must be filled with hyphens/dashes (–) if they are not applicable to the fan being considered.

Upblast (Direct Drive & Belted)
Series 61 – Direct Drive
The Series 61 upblast ventilator meets the need for an
economical, yet efficient upblast roof ventilator. The Series 61
unit combines the Hartzell ring fan concept with a windband and
butterfly damper.Dampers open automatically when the fan goes
on, close weathertight when the fan is shut down. When the unit
is in operation, the force of the discharge air effectively prevents
the entry of rain or snow.
Series 63 – Belted
The belted upblast ventilator, Series 63, offers the same design
and efficient performance as the direct drive model, along with
the added dividend of an economical approach to a low speed,
quiet upblast roof ventilator. The belted arrangement eliminates
the need for costly, low-speed motors for direct drive operation.
Since the drive assembly is in the ventilator’s airstream, the unit
should not be used to handle high temperatures or dirt-laden air.
Features:
• Sizes – Direct Drive (Series 61) – 12"-72"… performance from
1,390 to 88,000 CFM at free air. Belted (Series 63) –
24"- 84"… performance from 5,080 to 124,500 CFM at free air.
• Construction – steel construction is standard; aluminum
construction is available for “H” Duty only. Sizes through 60"
include painted, galvannealed weather exposed components.
Series 61
“G” Duty Shown
Series 63
“H” Duty Shown
On sizes 66" and larger, windband and panel are painted hot
rolled steel with industrial grade enamel. Motor base is heavy
gauge plate, welded to solid steel rod frame.
• Motor Mount – “G” (General Industrial) Duty construction
features an adjustable steel motor base and tubular steel frame,
which are over-sized to provide structurally rugged construction.
“G” Duty is available as Series 61 and 63 in sizes 18" to 48" and
will be limited by HP and RPM on certain sizes. Please
reference the performance rating tables, the shaded models are
those models offered as “G” Duty.
“H” (Heavy Industrial) Duty construction features solid rolled
rod supports, welded to the fan panel and motor mounts to
provide support for the motor. The steel motor base and solid
steel support rods are oversized to provide structurally rugged
construction. “H” Duty is available in all sizes and models.

Contact your Hartzell representative for assistance.
•
Motors – totally enclosed fan cooled motors are standard.
Special motors are available upon request.
•
Drive Assembly – Belted Only – drives are constant speed
and are sized to handle 20% or more horsepower than the catalog motor is rated.
•
Orifice Panel – sizes 12"- 60"… features painted galvannealed
steel venturi panel. Sizes 66"- 84"… formed steel panel with
angle ring orifice.
•
Windband – rolled, welded construction. Windband
effectively prevents wind resistance against the operation of the
ventilator. A rolled angle on top and bottom of the windband is
standard to provide additional support. Removable windband for
ease of maintenance of motor and drive assembly is standard
through 60".
•
Dampers – semicircular lids at the base of the windband are
mounted on corrosive resistant stainless steel rods which turn
in plastic bearings. Bearings will not rust or stick, and require
no lubrication. Lids open automatically when the fan turns on,
closes weathertight when the fan shuts off. Damper lids on all
sizes are constructed of galvanized steel as standard.
Aluminum and fiberglass damper lids are also available. See
Page 7 for CFM Limitations for Damper Lid Operation.
•
Coatings – special coatings are available upon request.
•
Extended Lube Tubes – will be provided from the motor on
direct drive units and from the bearings and motor on belt drive
and belted units to the exterior of the housing only when the
motor is designed for external lubrication fittings (relubricable
versus sealed motor bearings).
•
Pre-Assembled Units – 12" to 60" shipped in one piece.
66" through 84", the stack cap is shipped separately.
•

Upblast (Belt Drive) Smoke Ventilator
Series 69H
Hartzell Fan, Inc. originally pioneered the development of the first
powered smoke ventilator. Today, the Hartzell Series 69H
Upblast Smoke Ventilator meets or exceeds rigid I.R.I. (Industrial
Risk Insurers) Guidelines for Heat and Smoke Venting, No.
IM.2.1.4 (supersedes Guideline No. p.2.6).
An increasing number of insurance companies, local code
bodies, and business and building owners are requiring these
designated purpose ventilators to be installed, both in existing
buildings and new structures.
The advantages of a properly designed powered smoke
ventilator approach to the effective removal of hot gases and
smoke include:
– the provision of early access into the building by firefighters.
– reduce burden on the sprinkler system.
– reduced risk of personal injury and property loss.
Installing roof mounted gravity vents alone may be inadequate.
Variables such as inside and outside air temperature, wind velocity
and location of sprinklers can seriously affect the performance of
gravity vents. The Hartzell Series 69H Upblast Smoke Ventilator
is pre-engineered and designed to be used as a high temperature
powered roof ventilator. It is self-contained, ready to install, wire,
and put into service. Moreover, the Series 69H is a multi-use
product. It is designed to be used on a daily basis as a power roof
ventilator (special independent electrical connections may be
required), and as a gravity type roof ventilator in the event of a
power failure. Other specific features and advantages of the
Hartzell Series 69H follow.
Features:
•
Designed for continuous operation at 500°F exhaust air
temperature, with ambient air drawn through belt tube.
•
Size 18" - 60"... performance from 3220 CFM to 64,035 CFM
at free air.
•
Heavy gauge, all ferrous steel construction – includes
Hartzell's tested and proven belt drive duct fan design with
stack cap and curb panel for a complete vertical discharge roof
ventilator. Stack cap lids open automatically when the unit is
operating, close weather tight when the fan stops. On the inlet
side of the smoke vent, a curved inlet orifice increases the
efficiency and the performance of the ventilator. The curb panel
provides a convenient method of curb mounting the smoke
ventilator. The heavy gauge steel construction ensures the
unit's ability to withstand high temperatures and provides a
durable and rugged unit.
•
Welded steel propeller – three (3) bladed design with split
taper bushing for easy removal from shaft. Reinforcements at
the blade roots ensure stability and high stress characteristics.
The welded steel propeller offers similar efficiency to the
Hartzell cast aluminum lo-noise type propeller.
•
Open end, drip proof motors with 1.15 service factor. TEFC
and other motor enclosures are available upon request.
•
Combination motor cover and belt guard – this standard
feature provides weather protection and guards drive assembly.
Cover is vented and removable.
•
Belt drive arrangement – motor is mounted exterior to the fan
housing. Belts, bearings, pulleys and shaft are enclosed and
protected from the air stream. The drive assembly is located on
the negative side of the propeller; fan design provides for the
draft of ambient air from outside the ventilator in and over the
belts and bearings.
•
Belts – are heat resistant per I.R.I. standards. Drives feature
two (2) belts minimum.
•
Bearings – regreasable roller bearing type, supplied with high
temperature grease, designed for minimum four hours at
500°F. Copper bearing lubrication tubes are extended from the
bearings through the belt tube to the exterior of the fan
housing, allowing ease of maintenance.
•
Heat slinger – reduces heat conduction from the propeller to
the shaft and helps draw air through the belt and bearing tube.
•
Heat sinks – Aluminum plates dissipate radiant heat between
motor and duct housing, disconnect switch and mounting
bracket, and bearings and bearing base.
•
Fusible link – spring operated, positive lid opener. When the
temperature through the smoke vent exceeds 165°F, the fusible
link allows the spring operated lid opener to lock the stack cap
lids in the upright, open position. Provides gravity ventilation in
case electricity to the power ventilator is interrupted.
•
Disconnect switch – non-fused, rain tight, NEMA 3R
enclosure mounted on the curb panel and wired to the fan
motor provides safety during maintenance.
•
Safety coating – standard finish is high temperature black
enamel coating.
Accessories
•
Coatings – special coatings for corrosion resistance are
available upon request.
•
Pre-fabricated roof curb – 18 gauge galvanized construction
features full metal air stream liner. Available for flat, slope, or
peaked roofs. Available in 8" or 12" height.
•
Guard – inlet guard is constructed of expanded metal and
woven wire mesh. Outlet guard is spiral, ring type. (Can also be
used as a bird screen.)

Hooded Roof Ventilator
low-speed motors as in direct drive operations. Since the drive
assembly is in the airstream, Series 16 ventilators are designed
for clean air operation. Sizes 24" through 84", performance from
4,080 to 131,000 CFM at free air on intake; from 3,700 to 116,500
CFM at free air on exhaust. Also available as a Series 19I, 19E,
or 19F, with motor out of the airstream. See drawing on next page.
SERIES 17 (Direct Drive) and 17B (Belted)
Truly reversible airfoil fans offer 100% air delivery for both intake
and exhaust flows. Ratings vary slightly due to the
difference in pressure drops in the intake and exhaust modes.
This unit is ideal for applications where varying conditions call for
intake (supply air) for some operations, and exhaust flow for
others. Series 17 ventilators utilize the Hartzell reversible ring
fan incorporating two curved orifice rings welded back-to-back
with a reversible airfoil section propeller to provide efficient
performance when operating in either direction. Sizes 18" through
72"… performance from 3,220 to 96,700 CFM at free air on
intake; from 2,970 to 88,200 CFM at free air on exhaust.
Features:
•
Construction – ventilator hood and base are galvannealed
steel, painted with an industrial air dry enamel coating to
provide maximum protection from the elements. Aluminum
construction is also available for “H” Duty only. The fan frame is
painted mild steel. The hood is hinged on units through size 36".
This allows for the hood to be rotated to the side or removed for
access to the fan assembly. Sizes 42" through 84" feature split
hoods which are removable for access to the fan. These larger
sizes are available with Hartzell’s unique slide-rail access
package to allow easy separation of the hood halves for
inspection and maintenance (see page 22).
Standard construction on these units accommodates a
60 mph maximum wind load. Higher wind load construction
features are available as an option.
All hoods, size 36" and larger, are shipped separately from the
base and are to be mounted in the field. Lifting eyes and
hardware required for securing the hood to the base are
furnished as standard.
•
Motor Mount – “G” (General Industrial) Duty construction
features an adjustable steel motor base and tubular steel frame,
which are over-sized to provide structurally rugged construction.
“G” Duty is available as Series 15I, 15E, 15F, 16I, 16E, and 16F
in sizes 18" to 48" and will be limited by HP and RPM on certain
sizes. Please reference the performance rating tables, the
shaded models are those models offered as “G” Duty.
“H” (Heavy Industrial) Duty construction features solid rolled
rod supports, welded to the fan panel and motor mounts to
provide support for the motor. The steel motor base and solid
steel support rods are oversized to provide structurally
rugged construction. “H” Duty is available in all sizes and models.
•
Access Door – standard on all units.
•
Motors – totally enclosed fan cooled, foot mounted, T-frame
motors are standard. Special motors are available upon request.
See Motor Frame Size and Installation Weight Table for
maximum motor frame sizes. Belted units, Series 16, are
standard with adjustable motor slides for belt tightening.
•
Propellers – cast aluminum airfoil type. Several configurations
are available to accommodate maximum flow for a given size
and horsepower configuration. Typically, Hartzell 2, 3, 4 and 6
blade assemblies are used. They include the Hartzell Types N, P,
L, W, A, AW and BA designs for standard flow. The Type R and
Type AR blades are used for reversible type applications. Some
designs are fixed pitch; others are adjustable pitch.
Series 15 (Direct Drive)
The hooded roof ventilator design provides complete protection
from the elements for either exhaust or supply ventilation. The
unit’s large hood surface reduces the air velocities through the
ventilator. This feature minimizes pressure drop through the hood
and eliminates the entrainment of rain into supply units. The fan
assembly is placed in the upper section of the base, blades facing down, with the motor, drives, etc. located above the fan
assembly, for ease of maintenance.
The Hartzell hooded roof ventilators are designed with basic
function in mind; they facilitate mounting of optional items.
Hartzell has designed the Series 15 and 16 so that permanent or
disposable filters may be added to the hood as an accessory
item. Please refer to the separate rating table for filtered

Optional Filtered Hooded Ventilator
The Hartzell Series 15F (direct drive) and 16F (belted) hooded
roof ventilators are available with an optional filter rack, designed
to accept standard sized filters. Permanent, washable filters and
disposable filters are both available. This optional filter rack must
be installed at the factory. As described on Page 18, the
ventilator hood on sizes 18" through 36" is one piece. On size
42" through 84", the ventilator hood is in two pieces. Filters are
accessible by removing retainer clips in the filter rack for ease of
filter installation and maintenance.
When you specify the filter option, other options and features are
still available, including the slide rail package for split ventilator
heads shown in the illustration above.
On the pages that follow, actual filtered supply performance ratings
are provided for both the Series 15F and 16F hooded ventilators.
Features:
•
Sizes – Series 15F – Direct Drive – size 18" through 72"
performance from 1,375 to 88,000 CFM at free air.
•
Series 16F – Belted and Series 19F – Belt Drive – size 24"
through 84"… performance from 3,990 to 128,000 CFM
at free air.
•
Construction and Dimensions – are identical to the
standard Series 15F and 16F units. Please refer to Pages 17
and 18, “G” (General Industrial) Duty and “H” (Heavy Industrial)
Duty construction available. Refer to Rating Tables on Pages 23
and 24. The filter rack adds an additional 2
1
⁄4" to the overall
vertical dimension of the ventilator hood, but does not increase
the overall unit height.
•
Filters – permanent, washable filters are provided as standard
and the performance ratings that follow are based on losses
through permanent filters. Resistance through disposable
filters tends to be higher. Please refer to the resistance curve for
disposable filters on this page. Use of disposable filters will
cause the fan performance to change.
•
Other Options and Accessories – are available. Please see
Pages 33 and 34.

Features
•
Construction – galvanized steel base and hood; painted steel
orifice panel and fan frame. The hood is hinged to swing back
for easy access to the fan assembly. The airflow splitter in the
hood allows for the same high efficiency in either direction. The
aerodynamically designed hood provides a compact, low
profile. Hooded ventilators are also available in painted steel
and aluminum construction.
•
Motors – belted units (Series 73J) feature close-coupled drive
and totally enclosed fan cooled motors. Direct drive units
(Series 71J and 75J) feature totally enclosed air over motors.
•
Propellers – cast aluminum and airfoil type.
Options and Accessories
•
Shutters – automatic, motor, or manually operated shutters can
be mounted in either the throat of the unit or below the roof line.
•
Access Door – hinged door with quick release latches for
access to the interior of the hoodjet.
•
Bird Screen – half-inch square opening wire mesh, constructed
of either galvanized steel or aluminum.
•
Disconnect Switch – NEMA watertight enclosure available as
an option.
Hoodjet Ventilator
Series 71 J (Direct Drive)
Series 73J (Belted)
Series 75J (Reversible)
•
Extended Lube Tubes – will be provided from the motor on
direct drive units and from the bearings and motor on belt drive
and belted units to the exterior of the housing only when the
motor is designed for external lubrication fittings (relubricable
versus sealed motor bearings).
Hartzell Hoodjet Ventilators are available in three styles: (1) air intake;
(2) air exhaust; (3) reversible…combination intake and exhaust.
Direct Drive – Series 71J
An efficient, high performance ventilator, best suited for
applications where the unit is in a difficult location for servicing
and maintenance.
Sizes: 28" – 60" Performance from 5,480 to 36,500 CFM at free
air intake; from 5,480 to 60,600 CFM at free air exhaust.
Propellers: 28" – 60" 2-blade, Type N
28" – 60" 3-blade, Type L
28" – 44" 4-blade, Type W
28" – 44" 6-blade, Type P
48" – 60" 4-blade and 6-blade adjustable, Type A
Belted – Series 73J
The Series 73J is close-coupled, belt driven, with the motor in the
airstream. This ventilator utilizes Hartzell’s exclusive "L" propeller
which is designed to provide high volume airflow at low tip speeds
and relatively low noise levels.
Drive shafts are ground and polished, keyed at both ends.
Bearings are heavy duty, self-aligning, deep-row, radial ball type,
shielded and mechanically sealed in cast iron or malleable
housing; relubricable type for continuous service. Belts are oil,
heat and static resistant type, over-sized for continuous duty.
Sizes: 28" – 60" Performance from 5,870 to 40,550 CFM at free
air on intake; from 5,870 to 51,000 CFM at free air exhaust.
Propellers: 28" – 60" 3 blade lo-noise, Type L.
Reversible – Direct Drive – Series 75J
An ideal unit for applications where varying conditions may call
for intake during some periods and exhaust during others.
The Series 75J ventilator utilizes the Hartzell reversible ring fan
incorporating two-curved orifice rings welded back-to-back with a
fully reversible airfoil section propeller to provide the same
efficient performance when operating in either direction.
Sizes: 28" – 60" Performance from 6,800 to 44,700 CFM at
free air.
Propellers: 28" – 60" 2-, 4-, and 6-blade reversible, Type R.
Principal Dimensions – Series 71J, 73J and 75J
Specifications and dimensions are subject to change. Certified prints are available.
NOTES:
1. *“D” dimension is for all ventilators without shutters in throat, and for exhaust vents with
throat mounted auto or manual shutters.
2. *“D1” dimension is for intake or exhaust vents using motor operated shutters.
3. *“D2” dimension is for reversible vents using motor operated shutters.
4. Stutters are optional, and must be specified on order along with locations.
5. With “B” or “C” type bases, the “G” dimension may be lengthwise (L) – perpendicular to
slope or slopewise (S) parallel to slope. If slope exceeds 6 inches per foot, the “G”
dimension must be perpendicular (“L” type) to the slope when using “B” base.
6. When using either “B” or “C” base, the direction of the “G” dimension must be specified
as “BS”, “BL”, “CS” or “CL”.
7. Lube tubes extended to the outside of the base is optional.

Industrial, commercial, and residential spaces need proper
ventilation to facilitate a healthy and protective environment for
people, inventory, machinery, and structures. Ventilation itself
may be affected in a variety of ways, beginning with opening
windows and doors.
Typical industrial processes generate heat; people generate
heat; and building structures pass solar heat gains. Warm air
rises and can be trapped if not properly allowed to escape
causing stratification of air layers and contaminated conditions.
Power roof ventilators are an effective and efficient alternative
to ventilation by convection. The proper application and use
of power ventilators allows better control of air patterns and
air distribution.
Good, general ventilation practice and design ensures proper
dilution ventilation, heat load control, contaminated air exhaust,
and fresh air supply. As a result, operating personnel will be more
comfortable and efficient; manufacturing equipment and processes will be able to function more properly.
Selection of Power Roof Ventilators
Circulating Air Volume
The rate of air change is the most frequently used method for calculating air volumes for general conditions. It is based on the theory that a complete air change must be within a certain interval.
Listed below is a recommended guide for average air changes for
general ventilation.
Roof Ventilator Application
Rate of Air Change Method
The rate of air change will vary with the type of structure, but a
generally accepted rate is one air change every 5 minutes.
Air volume is found be determining the plant volume in cubic feet
to be ventilated and then dividing the cubic feet by the desired
rate of air change.
EXAMPLE: Ventilated area 120' x 50' x 20' = 120,000 cu. ft.
Air Exchange Rate - change every 5 minutes.
120,000 cu. ft.
5 min
= 24,000 CFM
Plant Layout
The usual method of designing plant ventilation layout is to first
determine the amount of CFM required (see above). Secondly,
determine the size and number of units needed to meet requirements. The units are generally symmetrically spaced.
EXAMPLE: Ventilated area 120' x 50' x 20'. Air Exchange
Rate - one change every 5 minutes.
120,000 cu. ft.
5 min.
= 24,000 CFM required
Determine number of ventilators required:
Divide 24,000 CFM (system requirement) by number of units
desired – in this case 2. Capacity requirement for each
ventilator – 12,000 CFM.
Symmetrical spacing should be used whenever possible; however, care must be taken to adequately ventilate particularly troublesome areas and that the roof ventilator air supply is not short
cycled by open windows, air supply unit or wall louvers.

Exhaust and Supply
Proper ventilation design is not limited to exhaust only. Any
volume of air that is exhausted from a space must be made up by
supply air in some fashion. Exhaust air will be made up to a
space either naturally, by entering through building cracks,
open doors, etc., or by proper ventilation design. Therefore,
air supply, in addition to air exhaust, should be considered.
In cooler climates tempered make-up air should be considered.
To effect proper sweeps and flows through the area to be
ventilated, supply air may be introduced through the side walls or
the roof. Contact your local Hartzell representative for
additional information on wall ventilators and make-up air units.
In many cases it may be necessary to filter the supply air. Please
see page 22.
There are basically two power roof ventilator configurations.
Upblast units are available for exhaust applications. They are
designed to throw the exhaust air volume up and away from
the building. When properly designed, exhaust air flow in
operation prevents the entry of weather; backdraft dampers close
securely to prevent air return and leakage when a unit
is not in operation. Hooded roof ventilators are available for
exhaust or supply. In the supply mode, hooded roof ventilators
can be fitted with permanent or disposable filters. When
properly designed, the ventilator hood accommodates low air
velocities so as to minimize static pressure losses through
the hood and prevent entrainment of weather when used in the
supply mode.
In addition, Hartzell offers a complete line of 100 percent
reversible roof ventilators when periodic operation in either mode
may be required.
Recirculating power roof ventilators which are designed
to intake fresh air, exhaust plant air, or recirculate clean plant air
are also available. Your Hartzell sales representative can provide
more information on these standard units.
Ambient Conditions
The ambient air temperature and air quality require attention when
power roof ventilators are being selected. Extreme heat or cold
may require special motor insulation (see the table that follows) or
bearings, lubricants, belts, and materials of construction.
Application Considerations
When a need for power roof ventilation has been identified and
your initial design and selections made, you should consider the
following items to ensure a proper, functional, and satisfactory
selection:
•
Maintenance – power roof ventilators are available in direct- and
belt-drive. Air quality, air temperature, and maintenance requirements for belts and bearings should be considered. Accessibility
for maintenance of the ventilator and accessory items is an
important issue.
•
Installation – power roof ventilator weights and sizes should be
considered for lifting methods and mounting on the roof. Proper
roof opening sizing, and free area in the opening are essential.
Power roof ventilators should be secured to the building structure
properly by means of attachment to a permanent structure or a
pre-fabricated roof curb (see page 34).
•
Power Supply – care should be taken to specify proper voltage, phase and cycle for the power roof ventilator motor as well
as accessories and controls.
•
Wind – care should be taken to ensure that exhaust and supply fan layout on the roof works with, rather than against, the
prevailing winds. For example, when power roof exhaust and
supply units are both used on the same roof, exhaust fans
should be positioned down wind of supply fans.
In addition, wind loads should be considered and standard units
modified or reinforced to operate properly in high-wind conditions (see page 34).
•
Options – see pages 33 and 34 for typical standard options and
accessories. Hartzell Fan, Inc. is able to modify standard products
and accessories to meet your special requirements.
Furthermore, for variable exhaust and supply requirements,
your Hartzell sales representative can assist you in the proper
application of AC speed controls with power roof ventilators.
Design assistance for proper plant ventilation is available
through recommended practices in industrial publications.
However, your Hartzell representative can provide you with
selection and application assistance based on experience
with a variety of solutions to general and process ventilation
problems. Contact your authorized Hartzell sales representative today.
Typical Application – Series 26
The Series 26, Recirculating Roof Ventilators and Series 27,
Recirculating Hooded Roof Ventilators provide roof ventilation
during the summer months and heat recovery in winter by
recirculating warm air from the ceiling down to floor level.
During the summer months not much can be done with hot
ceiling air but to exhaust it out of the plant by use of ventilators
and exhaust fans.
The huge reservoir of heated air resting at ceiling level can be
recirculated for comfort heating during the cold winter months,
providing the ceiling air is relatively clean and fume-free. In this
age of rising fuel costs, it doesn’t make "economic sense" to
exhaust warm ceiling air from a plant, then spend money for fuel
to heat cool air for worker comfort and efficiency.
Hartzell’s Recirculating Roof
Ventilators were designed
to economically solve both
summer ventilation and winter
heat recovery problems.
More than 70 Hartzell offices
can provide specific performance and installation data to
meet your requirements. Call
your Hartzell representative
for technical assistance.
Motor Insulation Maximum Ambient Temperature
Standard 105°F
Class F 140°F
Class H 176°F

Note: For extreme heat or cold, contact your Hartzell Sales Representative.
Corrosive fumes or dust in the air stream may require special
materials of construction or coatings. For some extreme
corrosive applications, Hartzell offers a complete line of upblast
and hooded fiberglass roof ventilators. Contact your Hartzell
sales representative for more information on the availability and
application of these products.
Noise
Power roof ventilators generate sound at different levels depending
on their power, efficiency, operating speed, and overall design.
This sound may be air borne or structure borne and should be
considered in accordance with industrial safety and hygiene
regulations. Slow-speed, high-volume, belted roof ventilators
(Series 16) are typically well suited for these applications. In
severe cases, attenuating devices and materials may be applied.
In addition to in-plant requirements, sound power levels at the
property line should also be considered.
