Quiet & Efficient
Plenum Fans
Models QEM and QEP plenum fans are designed and engineered to provide superior performance and reliability
in commercial or industrial applications. Our products are manufactured with
state of the art laser, forming, spinning and welding equipment and
endure our quality control testing to ensure trouble free start-up.
Plenum fans are designed to handle a variety of commercial and
industrial projects. They are designed for unhoused operation which
results in a savings of the space normally occupied by the
fan housing. Additional space savings are realized
when multiple duct takeoffs are required. Ductwork is
connected directly to the pressurized plenum without
intermediate transitions. Typical applications include:

Advantages of the QEM vs. QEP
Greenheck offers two solutions for your plenum design needs. The QEM is a cost effective
solution for performances in class I and most of class II as well. Fan selection is
simplified with one fan design for belt drive and another for direct drive, both
with motors mounted directly to the fan to reduce the fan’s footprint.
#PUIBSSBOHFNFOUTDPWFSUIFFOUJSF2&.PQFSBUJOHSBOHF8IJMF
the initial purchase cost of the QEM is lower than other plenum
fans, the QEM still shares the exact same performance
benefits of the high end model QEP.
Model QEP can be utilized when customers demand a
premium quality product, or need to reach performances in
the class III operating range. In addition to sharing the same
high-efficiency and low sound wheel design as the QEM,
the QEP also features longer life L10 80,000 hour bearings,
a powder coat finish, as well as a wider range of mounting
options and accessories.

performance is adequate, recent industry trends have seen the emergence
of 12-blade wheel designs where customers demand higher mechanical
efficiency and lower sound levels.
Model QEM and QEP plenum fans feature a 12-blade aluminum airfoil
construction wheel. As demonstrated in Figure 1, this 12-blade design
meets customer needs by providing higher efficiency, lower sound levels
as well as lower energy consumption.
Greenheck’s 12-blade wheel design features extruded aluminum blades
up to and including size 49, while the largest sizes utilize laser cut, dieformed aluminum blades. The two performance examples below demonstrate the
superior performance of the 12-blade design.

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

Air Plenum Design Guidelines
Effects of Air Density
To assure optimum performance and be able to use
the system effect coefficients below, the following
guidelines should be adhered to in the plenum design:
Ratings in the fan performance tables and curves of
this catalog are based on standard air: clean and dry
XJUIBEFOTJUZPGMCTGU3 at 70°F at a pressure of
29.92 in. of mercury. A change in elevation, temperature
or the type of gas handled will affect density. A fan
running at a constant speed and installed in a fixed
system will experience changes in pressure output and
horsepower consumption if the density of the airstream
varies. The air volume delivered by the fan will remain
constant regardless of air density.
1. Flexible connections at the inlet are recommended to
isolate vibration. The inlet connection can be square
(connected to the inlet panel) or round (connected
to an optional inlet collar).
2. Plenum walls should be at least one-half of a wheel
diameter away from the fan.
3. Dampers or coils should be at least three-quarters
of a wheel diameter away from the fan to assure an
even velocity distribution through them.
24 in. x 27 in.
(Radial)
4. For fans operating in parallel:
Have one wheel diameter clearance between
adjacent fans.
#BDLTUPQDMVUDIFTPSCBDLGMPXDPOUSPMEBNQFST
should be used to prevent windmilling of wheels if
fans are started or stopped at different times.
24 in. x 27 in.
(Axial)
Do not select fans near the top of the fan curve to
prevent unstable operation.

between the fans.
See AMCA Publication 201 for additional information
on this subject.
Duct System Effect
Reduction in cataloged air performance due to a plenum
around the fan is called a system effect. System effect
is a pressure loss, which must be added to the total
external static pressure of the duct system in order to
make the proper fan selection from catalog data. The
pressure loss calculation is based on the velocity of
the air in the discharge ductwork. As shown below, it
is derived by multiplying the appropriate coefficient by
the velocity pressure.

conditions and must be corrected to standard
DPOEJUJPOT UP VTF DBUBMPHFE EBUB 7PMVNF SFNBJOT
at 20,000 cfm, since the volume delivered is not
affected by air density.
2. An air density correction factor must be applied to
the static pressure. For an elevation of 13,000 ft. and
a temperature of 70°F, 1.6 is the required correction

System
Considerations
3. System effects for plenum discharges must also be
calculated and added to the design pressure. In a
properly designed plenum (see Duct System Effect
section), the system effect coefficient (Co) depends
on the orientation of the discharge relative to the fan
and duct connection (if any). For air plenums with
multiple discharges, calculate the system effect by
using the highest loss coefficient for all discharges.
In this example, the discharges are ducted so the
highest loss will be axial (Co

Selections
Direct drive construction offers many advantages for commercial or
industrial air handling applications.
- Reduced maintenance (no belts and shaft bearings to service)
- Compact housing design requires a smaller footprint
- Low vibration
- Suitable for clean air application (no belt or bearing residue in airstream)

The charts on these pages allow for a quick estimation of the required fan
size and motor speed to achieve the desired point of operation. Colored
bands for a given size in each chart show the acceptable performance
range for the most commonly selected fan sizes at a given motor speed.
