Greenheck Introduces Housed Plenum Array Fan, Model HPA - Podcast


Greenheck Plenum Fans are designed and engineered to provide superior performance and reliability in commercial or industrial air handling and pressurized plenum applications. The primary benefits of housed and unhoused plenum fans are compact sizes, flexibility to supply multiple air take-offs, and the economical price.


Plenum Fans

Overview

  • Model APD

    Model APD

    The APD is a commercial grade plenum fan that incorporates performance and reliability into a lighter duty, economical design. The compact direct drive APD eliminates the cost, maintenance and complexity of traditional belt drive plenum fans. When combined with a VFD, air volumes can easily be matched to changing building requirements or overcome increased pressures from dirty filters. APDs are an excellent option as stand-alone single fan or in parallel fan array applications. APD is constructed from a formed and bolted galvanized steel frame with a welded and coated steel 7 bladed, backward curved wheel.

    • 1,000 to 18,000 cfm per fan
    • Up to 10 in. wg
    • Certifications:
      • AMCA licensed for Air and Sound performance (AMCA 210 and 300)


  • Model APH

    Model APH

    APH plenum fans are designed and engineered for superior performance and reliability. It is available in both belt and direct drive with an extensive accessory offering. Quiet and efficient operation is achieved through a 12-bladed, airfoil aluminum wheel. This design saves energy and improves the overall sound quality by reducing low frequency tones that are difficult to attenuate. Model APH is ideal for industrial applications that require welded construction, coated framework, multiple configurations and the highest performance capabilities.

    • 1,000 to 209,000 cfm per fan
    • Up to 12.5 in. wg
    • Certifications:
      • AMCA licensed for Air and Sound performance (AMCA 210 and 300)


  • Model APM

    Model APM

    APM 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 bolt together framework that is either galvanized or coated, the APM features the exact same high efficiency / low sound 12-blade wheel as the APH plenum, but at a more cost effective price point for light and medium duty applications. APM units are available in belt and direct drive with basic accessory options.

    • 1,000 to 41,000 cfm per fan
    • Up to 8 in. wg
    • Certifications:
      • AMCA licensed for Air and Sound performance (AMCA 210 and 300)


  • Model HPA

    Model HPA

    The Housed Plenum Array (HPA) is a direct drive plenum fan mounted inside a sound attenuating housing designed to provide superior performance and reliability. It can be used as a single fan in a sound critical application or in parallel to construct a fan array system. The HPA features a modular design with a structural housing that allows multiple modules to stack side-by-side and on top of one another to form an array or fan wall. Typical applications include packaged, built-up and custom air handlers, general supply and return systems and retrofit projects.

    • 900 to 45,000 cfm per fan
    • Up to 7 in. wg
    • Certifications:
      • AMCA licensed for Air and Sound performance (AMCA 210 and 300)
