CENTRIFUGAL FANS

Plenum Fans

Greenheck Plenum Fans are designed for air handling and pressurized plenum applications. The primary benefits of plenum fans are compact sizes, flexibility to supply multiple air take-offs, and economical price.

Model QEP

QEP plenum fans are designed and engineered for superior performance and reliability. Quiet and efficient operation is achieved through a 12-bladed, airfoil wheel. This design saves energy and improves the overall sound quality by reducing low frequency tones that are difficult to attenuate. The QEP is available in both belt and direct drive and offers numerous accessories to complement your project.

Greenheck’s 12-bladed Quiet, Efficient Plenum model QEP will benefit your project by reducing electrical requirements and reducing the sound levels.

Sure-Aire

If your application requires real time flow measurement, the Sure-Aire is a great accessory to include.  The Sure-Aire provides the benefits of traditional flow probes which are placed in the airstream, but with the Sure-Aire's non-invasive design, fan performance is not affected.  For more information about the Sure-Aire system, including a head-to-head comparison video, click here.
