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)

#
APF

The APF is a lightweight and compact plenum fan model, ideal for horizontal wall mounting applications. It is an excellent choice for use in multiple fan array or retrofit applications. The axial flux motors have integrated controls that only need a 0-10V signal (4-20 mA option). There is no VFD and no additional wiring required to adjust speeds. The APF has a formed and bolted galvanized steel frame with a welded and coated steel, seven-bladed, backward-curved wheel.

  • 2,000 to 14,000 CFM per fan
  • Up to 6.5 in. wg

#
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
