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.
(Disconnect
switch is optional)

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.
