This duct booster fan kit is for HVAC professionals and facility teams that need to increase airflow in a duct line on demand. It helps support airflow where added duct boosting is needed.

Designed for 4-inch ductwork, this 120V duct booster fan delivers 173 CFM. Its galvanized metal housing includes a pressure-sensing switch on a 5-foot cord. The fan starts when positive pressure is detected in the duct and turns off after duct pressure returns to normal. Overall dimensions are 13 inches wide x 13 inches deep x 11 inches high.


Key Features:

  • Pressure-Sensing Control: Automatically starts the fan when positive duct pressure is detected and shuts it off when pressure normalizes.
  • 173 CFM Airflow: Provides duct-boosting airflow for compatible ventilation systems.
  • 4-Inch Duct Compatibility: Fits systems using 4-inch ductwork.
  • Galvanized Metal Housing: Provides a metal enclosure for the fan assembly.
  • Documented Certification: Performance is certified by HVI, and safety is certified by ETL to UL 507.
