Model PL: Plenum Fan

SUITABLE FOR DEMANDING AIR-MOVING APPLICATIONS

The Model PL plenum fan is engineered for efficient and reliable delivery of high air volumes in contained air‑handling systems, making it a strong choice for modern industrial and commercial HVAC applications. Designed without a traditional fan housing, the Model PL integrates directly into a pressurized plenum, optimizing space while improving airflow flexibility.

Cincinnati Fan manufactures twelve sizes of the Model PL, all configurable through multiple wheel designs and fan widths, allowing users to dial in precise system performance. The design supports both standard and high‑performance environments with optional aluminum or stainless‑steel construction for enhanced durability.

  • ADVANTAGES
  • DESIGN/CONSTRUCTION
  • APPLICATIONS
  • Resources
  • The elimination of a fan housing reduces cost andfootprint while allowing for more compact air‑handling unit (AHU) designs.
  • Because air discharges directly into the plenum, airflow exits the fan in any direction, often eliminating the need for diffusers, transitions, or complex ductwork geometries.
  • The PL series can be assembled in banks, allowing multiple smaller fans to replace one large traditional centrifugal fan. Multiple small fan array provides partial capability if one fan is out of service.
  • All models are available with four-wheel designs and in multiple widths from 50% to 100%, to deliver the exact performance you need with a direct-driven fan.
  • Available in all‑aluminum construction for lightweight, corrosion‑resistant applications or stainless steel for harsh, corrosive, or sanitary industrial environments.
  • Air handling unit retrofit
  • Built up air handling systems
  • Filtration systems
  • Air processing units
