Mancoolers
®
Greenheck Model MC Mancooler fans are direct drive, tube axial fans designed for applications where localized
air direction and circulation are required. Mancoolers increase comfort levels in high temperature work
environments, cool processes and equipment, remove smoke and fumes and generate a barrier for insects.
These fans are also effective in destratifying air. Warm air accumulated at ceiling level can be directed toward
the floor, and hot spots can be dissipated. Destratifying reduces energy costs and directs warm air where it is
needed. Multiple mancoolers can also be used as part of a general plant ventilation system to improve air quality
and general comfort.
All fans sizes have been thoroughly tested in Greenheck’s modern
AMCA registered research and development facility to ensure
complete and accurate performance ratings. Model MC is licensed to
bear the AMCA Certified Ratings Seal for air performance.
Sizes:
Available in seven sizes, 18 — 48 in.
Performance:
3000 - 33,000 cfm with guards
3400 - 37,000 cfm without guards
Standard Construction Features
Finish: All structural steel
components are coated
with Permatector™, a
thermosetting polyester
urethane, for a long lasting
finish.
Heavy duty ball bearing
motors are carefully
matched to the fan load
and are available open
drip proof, or totally
enclosed.
Rigid structural steel
motor supports are
welded to the fan
housing.
Housings are constructed of
heavy gauge, continuously
welded steel with rolled
inlet and outlet flanges for
additional strength and rigidity.
Performance capabilities are obtained through
combinations selected from a broad range of blade
options (2, 3, 4 or 6), propeller pitches and motor
RPMs (860, 1140 or 1725).
Model MC propellers and hubs
are designed to produce a high
level of efficiency over a broad
selection range. Tapered airfoil
blades are cast as one piece in
durable aluminum alloy. Each
propeller is statically and
dynamically balanced.
OSHA Guards
Protective guards are
constructed of welded
wire rings coated with
Permatector™. Rings
are spaced at a minimum
of 1/2 in. to meet OSHA
requirements.
Motor wiring
is provided to a
NEMA-1 handy
box mounted on
the exterior of
the fan housing.

Fans
Three mounting arrangements offer maximum directional flexibility and ease of mounting. Options include beam,
base (available with or without casters) and portable mounts.
Yoke Mount — Model MCY
This mounting arrangement allows
Model MC fans to be mounted
on vertical or horizontal beams.
Airflow direction is unlimited.
The fan housing can rotate
360° within the yoke, which can
also rotate 360° on its axis.
The beam mount allows the fan
to be mounted near the ceiling to
destratify trapped warm air. This
results in reduced heating costs.
With maximum directional flexibility,
the beam mounted fan can also be
positioned to provide spot cooling
in the exact location required.
To ensure proper installation,
the beam or other structure the
Base Mount — Model MCB
The base mount allows Model
MC fans to be mounted directly
to floors, walls or ceilings. Fans
can be rotated a full 360°.
Mounted high on walls or ceilings,
Model MC fans can circulate
heated air and reduce heating
costs. They can also be mounted
near heat-producing processes
to balance temperatures and
cool personnel in the vicinity.
The caster mounted option
(shown above) allows even the
largest size fans to be portable.
Model MC fans are designed for
stability with wide-set casters
and a low center of gravity.
fan is to be mounted on must be
capable of supporting fan weight.
Multiple Mancooler Installation
Multiple mancoolers can be used as part of a general plant
ventilation system to improve air quality and individual comfort. In the
winter, they can move hot air from the ceiling to the floor and break
up hot spots generated by unit heaters. (see diagram).
Portable — Model MCP
This portable mount is available for
Model MC fan sizes 18 through 36
inches. Single phase motors are
recommended. Two polymer wheels
and a steel handle are attached to
the fan housing. Housing position
is fixed to deliver horizontal airflow
(fan housing does not rotate).
Where cooling needs do not
require a large fan but do
require portability, the portable
mount option is the most
economical option for process
and personnel cooling.
Options and Accessories
Casters - Four casters allow base mounted fans to be moved
easily. Casters are constructed with durable, non-marketing
polymer wheels. Two of the four are fixed in position. The
other two swivel and lock.
Inlet Bells - Inlet bells minimize entry losses and increase
outlet air volumes approximately 8%.
Special Coatings - A baked enamel finish is available to
match or complement building color. Protective coatings are
also available. These include epoxy, tung oil phenolic and air
dry phenolic.
Disconnect Switches - NEMA 1 disconnect switches are
available for applications where a visible disconnect is
required to be mounted on the exterior of the unit for positive
electrical shutoff or when servicing the fan. Other switch
enclosures are available upon request.

Sound
The sound power that a mancooler emits is another consideration in fan selection. All sound tests were
conducted in accordance to AMCA Standard 300, Figure 1 - “Total Sound Testing”. This test method includes the
sound power generated at both inlet and outlet and also includes the sound radiated from the fan casing. Sound
power levels at eight octave bands are available from the factory upon request.
To simplify the sound data, a single number sound pressure level (dBA) has been calculated and included in the
performance page. This number is a logarithmic sum of the A-weighted pressure levels in each octave band
calculated at a distance of 5 ft. from the fan. The A-weighting network is a correction applied to the measured
sound which accounts for the response of the human ear to sound pressure.
Sound pressure levels are roughly proportional to the tip speed of the propeller (rpm x propeller diameter). For
a given diameter fan, higher motor speeds will generate higher sound levels. For a given motor speed (e.g. 1140
rpm), larger diameter fans will be louder.
The following chart suggests fan sound pressure levels for different applications. Fans and other equipment that
generate a room sound pressure level of 85 dBA or greater are subject to OSHA regulations. Ambient sound
levels of installation site should be considered in making the fan selection. Fan dB rating should not exceed
ambient sound level where sound is a critical factor.

The sound pressure levels shown in the performance pages are calculated at a distance of 5 ft. from the
fan. Sound pressure levels are reduced 6 dB for each doubling of the distance from the fan. For example,
a mancooler that generates 86 dB at 5 ft. will measure 80 dB at 10 ft. and 74 dB at 20 ft. Since tube axial
mancoolers have a relatively long throw, they can be located far from the worker level.
The air and sound application data in this catalog was based on actual tests conducted in Greenheck’s
laboratory without the presence of obstructions in the airstream. Walls, ceilings, equipment and other high
velocity airstreams will disturb the airflow and serve as sound reflecting surfaces. These obstructions to airflow
must be accounted for by the system designer when sizing and selecting mancoolers.

Engineering Data
Selection
To make a Mancooler selection from the performance pages, the CFM and/or outlet velocity must first be
determined. The CFM is used mainly as an indicator of air mixing capacity. The outlet velocity is used to
determine the terminal velocity at a specified distance from the fan.

(Outlet Area)
The air velocity downstream from the fan depends on the initial outlet
velocity, the fan diameter, and the distance from the fan.
K (O.V.) = K (cfm)
VCL =
X X (O.A.)
VCL = Maximum velocity along the centerline of the fan [fpm]
O.V. = Outlet velocity - CFM divided by fan outlet area [fpm]

An approximate airstream velocity used to cool personnel is 150 fpm. Light objects such as papers on a
desk tend to move at about 170-190 fpm. Velocities over 400 fpm should be avoided in applications for
cooling personnel.
