OVERVIEW
#
APD

Model APD is a commercial grade plenum fan combining performance and reliability into a lighter duty, economical design. The compact direct drive eliminates the cost, maintenance and complexity of traditional belt drive, plenum fans. When combined with a variable frequency drive (VFD), the fan unit allows air volumes to adjust to changing building requirements such as increased pressure from dirty filters. APDs are an excellent option as a stand-alone single fan or in parallel fan array applications. The APD has a formed and bolted galvanized steel frame with a welded and coated steel seven-bladed, backward-curved wheel.

  • 1,000 to 18,000 cfm per fan
  • Up to 10 in. wg
Certifications:

AMCA licensed Air and Sound (AMCA 210 and 300)

#
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. It uses a bolt together framework that is either galvanized or coated. The APM has the same high efficiency / low sound 12-blade wheel as the APH plenum, but at a cost effective price 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

APH

APH plenum fans come in belt and direct drive versions with an extensive accessory offering. A 12-blade, airfoil aluminum wheel achieves a quiet and efficient operation. This design saves energy and improves the overall sound quality by reducing low-frequency tones that are difficult to attenuate. Industrial applications are ideal for the APH because of its welded construction, coated framework and multiple configurations.

  • 1,000 to 209,000 cfm per fan
  • Up to 12.5 in. wg

#
HPA

The HPA model is a direct drive plenum fan mounted inside a sound attenuating housing. Use as a single fan in sound critical applications or in parallel to construct a fan array system. Its modular design with a structural housing 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
