Safety Precautions for Installation

Since Breezeway fans contain rotating parts, PennBarry
recommends the following safety precautions be taken during
installation, operation and maintenance. Install FAN GUARDS
on all non-ducted fan installations to protect people working
around the fan and to protect the fan from foreign objects
coming into contact with moving parts. For proper and safe
operation, fan RPM should not exceed that recommended in
performance tables.

PennBarry provides a wide variety of accessories for the Breezeway
propeller fan line. The components shown below can be mixed and
matched to suit the demands of the particular application.

Weathershields are designed to divert rain and snow from exhaust and supply wall openings.
They are designed to be surface mounted and can be installed in conjunction with wall shutters.
Guards are provided. Standard construction is galvanized steel, painted upon request. In order
to minimize shipping costs, the weathershield will be shipped knocked down for the BHM and
BHH products, unless factory assembly is specifi ed. Other models will be shipped factory
assembled.

Use the tables below to help with space planning and sizing guidelines. Please note the maximum
recommended intake (supply) CFM. This guideline will keep the intake CFM below 500 FPM.

Wall Shutters

Type WSR recessed gravity shutters, the most
popular form of backdraft protection, open when
the fan starts and automatically close shut when
the fan stops. These shutters are used for exhaust
only and are enclosed within a heavy, steel frame
that protects the roll-formed steel blades. Each
blade pivots freely on nylon bearings. Blades
are interconnected with one or more tie-rods
for simultaneous operation. Consult factory for
surface mount shutters, if required.

Type EBR is the motorized version of the gravity
WSR. It includes all of the WSR features plus an
enclosed actuator motor for positive opening and
closing of the shutter. The motor is fi eld wired in
parallel with the fan. Allow a minimum 7" between
the fan and the shutter when motorized. Larger
actuators will be provided with a transformer for
460V.

Shutters required for supply applications are
provided as motorized center-pivot type (not
illustrated.) If standard top-pivot shutter is used
for supply applications, a fi eld supplied time delay
relay is strongly recommended.

Caution: When a Breezeway fan is selected
for a supply application, fan velocities greater
than 500 FPM can pull water into the structure.
We suggest that a PennBarry Weathershield be
selected in supply applications to help prevent
water penetration when high velocity conditions
cannot be avoided.

Paint and Coatings

In most cases, the standard epoxy fi nish is suffi cient to provide
years of attractive life to your propeller fan. For those cases
where corrosive fumes are encountered or where special
protective fi nishes are otherwise needed, the Breezeway can
be provided with special coatings. Accessories for BHM/BHH
will be provided assembled, not knocked down, if painting is
specifi ed.

Disconnect Switches

Safety disconnect switches are required under the National
Electric Code whenever an electric power source is controlled
from a switch or panel that is out of sight of the operated
equipment. Factory wiring is not available for explosion proof
motors.

Motor Selection

Breezeway

After choosing a fan model, it is important to review the motor
availability charts to verify that the desired voltage, phase and
motor enclosure is available. Some factors affecting motor
selection are discussed below.

Electric Power Considerations

First, determine the nature of the electric power feeding
the motor. Is it single phase or three phase power? Next,
determine the required line voltage. Is it 115V, 230V, 460V?
Then determine the frequency. Is it 60 Hz or 50 Hz?

Environmental Considerations

Most clean air fan applications utilize Open Drip-Proof
(ODP) motors. Hazardous environments require Explosion
Proof motors. Explosion Proof motors are rated for NEMA
Class 1, Group D, Div. 1 and Class II, Groups F and G,
Div. 1 applications. Dirty environments require TE motors.
Ambient temperatures above (50 deg C) require special
motor construction. When in doubt, consult your PennBarry
representative or the factory for application assistance.

Caution: Hazardous environments also require special
fan construction suitable for the conditions.

Fixed Speed Motor Control

Two-speed motors, used in conjunction with external switches
or sensors (gas concentration, odor, temperature, etc.), are
used to adjust the airfl ow through the ventilator by changing
from one fi xed speed to another. Typical two-speed motor
designation is 2-speed, 2-winding (1800/1200 Nominal RPM).
2-speed, 1-winding motors (1800/900 Nominal RPM) are
available for 3-phase power only. Dual voltage motors are not
available in a 2-speed confi guration.

Variable Speed Motor Control

PennBarry Lek-Trol™ solid state controllers are an economical
way to reduce the high speed of selected P Series motors
by as much as 50%. Check the Lek-Trol™ availability table
on the following page to verify suitability for the fan model
selected.

Motors suitable for use with fi eld supplied Frequency Inverters
can be supplied for BLL, BHM, BHH, BC and BCH models.
Contact your PennBarry representative.

High-Effi ciency Motors

Motors that comply with the requirements of the energy Policy
Act of 1992 are provided when the required voltage, speed
and enclosure are applicable.

The above values of full-load currents are typical for motors
running at speeds usual for belted motors and motors with
normal torque characteristics. Motors built for low speeds
(1200 RPM or less) or high torques may require more running
current, and multi-speed motors will have full-load current
varying with speed, in which case the nameplate current
ratings shall be used.

The voltages listed are rated motor voltages. The currents
listed shall be permitted for system voltage ranges of 230 to
240 and 440 to 480 volts.

The table data shown above is from the NEC 2005 edition,
table 430-150.

The amperages given here are approximate values only and represent averages compiled from the tables of leading motor
manufacturers. Overload relay heaters should not be selected on the basis of these tables only. Heaters must be selected in
accordance with the actual motor current as shown on the nameplate. It is also important that ambient temperatures of the
area in which the motor control is located be taken into consideration when making heater selections. Ambient compensated
overload relays are available for abnormal temperature conditions.

P Series Fan Curves

The fan curves illustrated here show the range of capacities
available for P series direct drive units. Each graph shows
the performance of several models at one particular nominal
speed. Fan curves provide a quick method for selecting a fan
unit based on design point requirements.

The direct drive performance chart on the previous page
provides the tabular data (CFM and static pressure) used to
plot the fan curves. In addition, horsepower, tip speed and
sones are tabulated. Since sound is normally an important
factor in the selection of a fan, an engineer will usually

Direct Drive Fan Data

Breezeway

want to select the “slowest” unit which meets CFM and SP
requirements.

Please refer to the Motor Selection section to make sure the
motor you select meets your electrical requirements.

Note: Breezeway fans are only one component of a total
system. As such, fan performance is directly affected by the
system. It is critical that system designers determine the actual
system loss to ensure that the actual fl ow is specifi ed in the
system design.

Belt Drive Fan Data

Breezeway

Performance Data

The belt drive models shown on the following pages have
sizes and capacities ranging from below 3,000 CFM to nearly
70,000 CFM, with static pressures from 0" to above 1 1/2".
All models are available in several different horsepower sizes
with a wide range of RPM.

The data provided for each belt drive model includes:

• Tabular performance data

• Fan curve

• Dimensional and physical data

Each curve graphically displays the range of capacities
available for each model, in most cases beyond the specifi cs
shown in the tabular data. The maximum performance afforded
by each horsepower is indicated by dashed lines and the RPM
is indicated by solid lines.

Refer to the appropriate Motor Availability chart (see Motor
Selection section) to confi rm available motors.

The belt drive models have graphs that show both shaded
and unshaded areas. Caution should be used when making
selections in the shaded areas.

The highest RPM shown for a specifi c horsepower in the
tabular data is the maximum speed that for any point along
the performance curve, the BHP will not exceed the available
horsepower.

Always consider belt drive losses into the BHP calculations
to ensure proper motor selection. PennBarry fan selection
software ALWAYS accounts for these losses. See ‘Belt Drive
Losses’ section, following, for an explanation of this topic.

Note: Breezeway fans are only one component of a total system. As such,
performance is directly affected by the system. It is critical that system designers
determine actual system losses to ensure that the actual fl ow is specifi ed in the
system range.

Belt Drive Losses

The AMCA Review Committee has developed the chart
shown below for the purpose of estimating belt drive losses.
To calculate total BHP (including drive losses): Find the BHP
of your operating point on the x-axis on the graph below.
Follow the vertical line to the lines indicating the range of drive
losses. Look at the y-axis on the left and fi nd the drive loss
percentage. Calculate the total BHP by adding the drive loss
to the operating point BHP. For BHP’s below 0.3, use 30%.

Caution: For totally enclosed, explosion proof, multi-speed
and all 1.0 Service Factor motors, fan BHP plus drive losses
should not exceed motor rated HP.

Note: FanSizer software incorporates a drive loss allowance when selecting a
required nominal horsepower.

Range of drive loss for standard
belts. Higher fan speeds tend to
have higher losses than lower fan
speeds at the same horsepower.

Safety Precautions for Installation

Since Breezeway fans contain rotating parts, PennBarry
recommends the following safety precautions be taken
during installation, operation and maintenance. Install FAN
GUARDS on all non-ducted fan installations to protect
people working around the fan and to protect the fan from
foreign objects coming into contact with moving parts. For
proper and safe operation, fan RPM should not exceed
that recommended in performance tables. Installations that
result in EXCESSIVE VIBRATION are unacceptable.

Sound Power Levels

Since any mechanical device generates some sound energy
into the air, fans will create some noise. Because of the great
number of factors infl uencing sound output it is invalid to
compare fans based on RPM, tip speed or outlet velocity. The
only accurate basis of comparison is the sound power level
generated by the fan at the required point of operation.

Having sound power levels for a specifi c fan at a specifi c
operating point allows the system designer to determine the
theoretical sound pressure level at any point in the occupied
space. AMCA Publication 303 and the ASHRAE Guides
provide more information on this process. Another typical
application of sound power levels is to compare similar fans.
Generally differences of 6 dB in the 63 Hz band and 3 dB in
all other bands are considered insignifi cant.

System designers use many methods to predict acoustic
acceptability of an occupied space.

The A-weighted sound pressure level provides a single
number that corresponds well to the human judgement of
relative loudness. OSHA bases their requirements regarding
exposure to noise on A-weighted sound pressure levels. The
disadvantage of this method is that A-weighted sound pressure
levels do not provide information as to the quality of the sound.
Noise Criteria (NC) curves are also widely used. To determine
the NC level, the sound power spectrum is compared to
defi ned limits. Other methods include RC curves, Sones, SIL
and Noise Rating Curves.

Each method relies on sound pressure level information
because the human ear “hears” sound pressure fl uctuations,
not sound power (watts). Sound pressure is a function of the
attenuation of the space and the distance from the source.
Consider a 100 watt light bulb. It provides adequate light for
a closet, but not for a classroom, and in a stadium it would
be imperceptible. While the light source was the same power

(100 watts), the brightness level changed dramatically.

Similarly, the same sound power level (acoustical energy)
produces greatly different sound pressure levels (noise).

Sound power levels shown in this catalog were measured
and certifi ed using AMCA standard 300 Reverberant Room
Method for Sound Testing of Fans. The values shown are for
the eight octave bands defi ned in this standard, which agree
with ANSI 61.11-1986. One-third octave band sound power
levels shown are rated in decibels (dB) using 10-12 watts as
a reference.

Sone Ratings

In addition to sound power levels, PennBarry has provided
sone ratings to allow designers to make an educated judgment
as to the noise level a fan will develop in a space. Sone
ratings are a loudness index developed from sound power
level data. The calculation is at 5’ from the fan inlet and in
front of a refl ecting plane (hard wall). Sones are weighted
similarly to the A-weighting scale in that more weight is given
to frequencies that people can hear “well” and less weight to
frequencies that people do not hear “well”. A signifi cant feature
of the sone scale is that it is linear rather than logarithmic.
This means that 40 sones is 33% louder than 30 sones, as
opposed to 40 dB being twice as loud as 30 dB.

Since the sone rating is determined from well defined
assumptions and is linear in nature, it is ideal for comparing
different fans moving air at the same CFM and SP. When using
sones for this purpose, differences of 3 sones are considered
negligible. The suggested loudness level chart below is a
practical guideline for acceptable installed performance.

The sone values shown in this catalog are based on the sound
power levels determined above, and calculated in accordance
with AMCA Standard 301 “Methods for Calculating Fan Sound
Ratings from Laboratory Test Data.”

Fan Laws

The following section includes engineering and technical data,
guidelines and system explanations related to air moving
and control devices. Fan laws and system descriptions are
consistent with industry standards, defi nitions and accepted
practices. This information is provided to assist system
designers in sizing, selecting and defi ning their air moving
and control systems as well as explaining variables inherent
in system design.

There are nine fan laws, three are of prime importance to the
understanding of ventilation systems. These, together with an
appreciation of fan types, should help avoid most problems
with poor airfl ow performance. These three laws assume the
same fan operating with air at a constant density.

1. Airfl ow and fan speed are directly proportional.

CFM

CFM

CFM1 is the original fl ow rate in cu. ft. per minute.
CFM2 is the desired fl ow rate in cu. ft. per minute.
RPM1 is the original rotational speed of the fan.
RPM2 is the desired rotational speed of the fan.

Interaction of Fan Curves and System Curves

A ventilation system using a Breezeway may consist of a fan
with duct connected to the inlet side. Control dampers, grilles,
registers and duct fi ttings may also be part of the system.
The fan is the component in the system which provides
energy to the airstream to overcome the resistance to fl ow
off the other components. The determination of the “pressure
loss” or “resistance to fl ow”, for the individual components
can be obtained from the component manufacturers. The
determination of pressure losses for ductwork and branch
ductwork design is well documented in standard handbooks,
such as the ASHRAE Handbook of Fundamentals.

The fan curve shown in Figure 1 is a typical fan performance
curve, developed through the actual testing of a fan in an
air tunnel. The fan is run at constant speed and constant air
density. When the fan is installed in the fi eld, then it becomes
part of the system. System curves are developed by using fi eld
tested data and applying fan laws. The point of intersection of
the system curve and the fan performance curve determines
the actual fl ow volume. If the system resistance has been
accurately determined, and the fan properly selected, the
performance curves will intersect at the system design point
(point A).

or airfl ow.

Engineering Notes

Breezeway

If the system resistance has been underestimated, then fan
curves and system curves will not intersect at the system
design point. They will intersect at lower CFM (point B). If the
system resistance has been overestimated, then the fan curve
system curve will intersect at a higher CFM than the system
design point (point C). (See Figure 1)

Effect of Change in Density, Altitude and Temperature
Correction Factors

The resistance of a duct system is dependent upon the density
of the gas fl owing through the system. A gas density of 0.075

is standard in the fan industry.

lb/ft

Pressure and horsepower vary directly as the ratio of the gas
density at the fan inlet to standard density. This density ratio
must always be considered when selecting fans. To select
a fan, pressure should be corrected to standard air density,

Inlet System Effect

The most common installation problem is ductwork connection
to the inlet side of the fan. Here are several design criteria
for connecting ductwork to the fan. Keep a straight duct run
twice the diameter of the inlet size immediately before the
inlet of the fan. This will give the air a chance to straighten
out before entering the fan. Fan inlet swirl and non-uniform
inlet fl ow can often be corrected by inlet straightening vanes
or guide vanes. Restricted fan inlets located too close to walls,
obstructions or restrictions caused by a plenum or cabinet, will
decrease the useable performance of a fan. Cabinet clearance
effect or plenum effect must be considered a component
part of the entire system; the pressure losses through the
cabinet or plenum effect is considered as a System Effect
when determining system characteristics. The backdraft

damper is part of external static pressure, and should be
accounted for when estimating system static pressure. Use
a motorized backdraft damper when the fan has a variable
speed controller.

System Effect

A System Effect Factor is a pressure loss which recognizes
the effect of fan inlet restrictions, fan outlet restrictions or other
conditions infl uencing fan performance when installed in the
system. Figure 2 illustrates defi cient fan/system performance
resulting from one or more undesirable fl ow conditions. It is
assumed that the system pressure losses, shown in system
curve A, have been accurately determined, and a suitable fan
selected for operation at Point 1. However, no allowance has
been made for the effect of the system connections on the
fan’s performance. To compensate for this System Effect, it
will be necessary to add a System Effect Factor (SEF) to the
calculated system pressure losses to determine the actual
system curve. The SEF for any given confi guration is velocity
dependent and will, therefore, vary across the range of fl ow
volumes for the fan.

In Figure 2, the point of intersection between the fan
performance curve and the actual system curve B is Point

4. The actual fl ow volume will, therefore, be defi cient by the
difference from 1-4. To achieve design fl ow volume, an SEF
equal to the pressure difference between Point 1 and 2 should
have been added to the calculated system pressure losses and
the fan selected to operate at Point 2. Note that because the
System Effect is velocity related, the difference represented
between Points 1 and 2 is greater than the difference between
Points 3 and 4.

The SEF includes only the effect of the system confi guration
on the fan’s performance.

Engineering Notes

Breezeway

Inlet Duct Elbows

Non-uniform fl ow into a fan inlet is the most common cause
of defi cient fan performance. An elbow located at, or in
close proximity to the fan inlet will not allow the air to enter
the impeller uniformly. The result is less than cataloged air
performance.

Inlet Vortex (Spin or Swirl)

Another major cause of reduced performance is an inlet
duct condition that produces a vortex or spin in the airstream
entering a fan inlet.

The ideal inlet condition is one which allows the air to enter
axially and uniformly without spin in either direction. A spin
in the same direction as the impeller rotation (pre-rotation)
reduces the pressure volume curve by an amount dependent
upon the intensity of the vortex. The effect is similar to the
change in the pressure volume curve achieved by inlet vanes
installed in a fan inlet; the vanes induce a controlled spin in the
direction of impeller rotation reducing the volume fl ow rate.

A counter-rotating vortex at the inlet may result in a slight
increase in the pressure-volume curve but the horsepower
will increase substantially.

Inlet Turning Vanes

Where space limitations prevent the use of optimum fan inlet
connections, more uniform fl ow can be achieved by the use
of turning vanes in the inlet elbow.

Numerous variations of turning vanes are available from a
single curved sheet metal vane to multi-bladed “airfoil” vanes.
The pressure drop through these devices must be added to
the system pressure losses.

Spark Resistant Construction

AMCA standards offer the following defi nitions and notes
concerning spark resistant construction:

C – The fan shall be constructed so that a shift in the

impeller or shaft will not permit two ferrous parts of
the fan to rub or strike.

B – The fan shall have a non-ferrous impeller and non-

ferrous ring about the opening through which the
shaft passes. Ferrous hubs, shafts and hardware
are allowed, provided construction is such that a shift
in impeller or shaft will not permit two ferrous parts
of the fan to rub or strike. Steps must also be taken
to insure that the impeller, bearings, and shaft are
adequately attached and/or restrained to prevent a
lateral or axial shift in these components.

Notes: 1) No bearings, drive components or electrical components shall be placed in the air or gas stream unless they are constructed or enclosed in such a manner

that failure of the component cannot ignite the surrounding gas stream.

2) The user shall electrically ground on all fan parts.

3) For this standard, non-ferrous shall be any material with less than 5% iron or any other material with demonstrated ability to be spark resistant.

4) The use of aluminum or aluminum alloys in the presence of steel which has been allowed to rust requires special consideration. Research by the
U.S.Bureau of Mines and others has shown that aluminum impellers rubbing on rusty steel may cause high-intensity sparking.

The use of the above standard in no way implies a guarantee of safety for any level of spark resistance. Spark resistant
construction does not protect against ignition of explosive gases caused by catastrophic failure or from any airstream material
that may be present in a system.
