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.

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 L

80,000 hour bearings,
a powder coat finish, as well as a wider range of mounting
options and accessories.
