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.

Overview

  • Model QEM

    QEM plenum fans provide high efficiency while maintaining a compact size. This is an excellent selection for retrofit and replacement applications and in variable air volume systems. Utilizing a galvanized framework, the QEM features the exact same high efficiency / low sound 12-blade wheel as the QEP plenum, but at a more cost effective price point for light and medium duty applications. QEM units are available in belt and direct drive with a simplified selection of accessories.


  • 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.
