high efficiency and low sound 12-blade airfoil
design. The aluminum wheel reduces start-up
torque requirements as well as shaft loading during

blades to improve efficiency and reduce vibration. All
wheels are balanced to grade G6.3 per ANSI S2.19.

AMCA Air and Sound Certification

AMCA certification assures that all Greenheck plenum
fans will perform as cataloged. Fans are rated for air
performance as well as sound levels (inlet and outlet).

Quality Assurance

All plenum fans receive
a run test at the design
speed in the factory after
final assembly. QEM fans
are checked for amp draw
and the levels recorded.
QEP fans are subjected
to a complete vibration
analysis in three planes.
The recorded filter-in
vibration levels must meet

A permanent record of this test is kept on file at the
factory for future reference. A copy of the test report
is available upon request.

Premium Quality Bearings

tolerance for swivel torque,
noise levels and bore size
specifications. Other
bearing design features
include concentric
mounting collars (no set
screws) which provide
superior grip force between
the collar and the fan shaft
as well as zerk fittings for
lubrication.

Drive Frame

All plenum fans feature
a laser cut and formed
framework. Model QEM
utilizes a galvanized
construction, while the
QEP features a fully
welded design with
Permatector™, an electrostatically applied polyester
urethane powder coat finish.

Fan Shaft

CAD Drawings Available

To assist with system design and layout, 2D CAD files
for all plenum fans are available. Drawings can be
downloaded directly through the CAPS program after
product selection at www.greenheck.com or consult
