Suncourt Centrax 4" In-Line Centrifugal Fan (TF104-CRD)
Suncourt Centrax 4" In-Line Centrifugal Fan (TF104-CRD) - Boost Airflow - The Suncourt Centrax TF104-CRD 4" In-Line Centrifugal Fan mounts to your air duct and is the ideal solution to boost airflow, move air or exhaust air.

Typical applications for the centrifugal fan include pushing cold air to upper floors in the summer time, moving air long distances, pushing warm air down from high ceilings, and dryer vent boosting when the duct for the dryer is longer than 15 feet. It can also be used for bathroom ventilation, crawlspace ventilation and Radon Mitigation (or as a replacement fan for an existing Radon Mitigation Fan).
