Quiet & Efficient, Inline

Mixed Flow Fans

Mixed flow inline fans can be used for supply, exhaust,
or return air installations. Our patented design excels
in commercial applications where low sound is critical.
In addition, Greenheck's mixed flow fans are more
efficient than comparably sized tubular centrifugal
and vane axial fans, thus reducing the required motor
horsepower and lowering operating costs.
Greenheck's mixed flow fans are the quietest tubular
inline fans in the industry!
• Performance as cataloged is assured. All sizes are
licensed to bear the AMCA Certified Sound (both
inlet and outlet) and Air Performance Seal.

• All sizes are tested before they leave the factory to
ensure trouble-free operation at the jobsite.
• Compact size and a "Universal Mounting System"
make tight space considerations and last minute
mounting changes easy to handle at the jobsite.
• The belt drive models use air handling quality
bearings that are 100% inspected for swivel torque,
noise levels, and bore tolerances.
• These products are subjected to extensive life cycle
testing, assuring many years of reliable performance.

Typical Mixed Flow Applications:

Recommended for any ventilation application that
requires low sound and high efficiency, such as office
buildings, parking garages, concert halls, libraries,
and educational facilities.
