Modular Plenum Fan, Airfoil Impeller,
9-Blades, Arrangement 4, Insulated


MPLFN Plenum fans are used in field-fabricated or factory-built air handling units to pressurize the entire surrounding air plenum. This allows discharge ductwork to be directly connected to the air handler from any direction. The plenum fan design also saves space by eliminating the fan housing, transitions and diffusers within the air handling unit.

Sizes (impeller diameters)

  • 12.25 to 36.5 inches (315 mm to 930 mm)


  • Airflow to 44,000 CFM (74,800 m3/hour)
  • Static pressure to 12 inches w.g. (2,980 Pa)
