AC Infinity Raxial S4, 4 Inch Duct Booster Fan

AC Infinity Raxial S4 is a 4-inch duct booster fan engineered to increase airflow in HVAC ducting and improve ventilation in spaces like attics, workshops, bathrooms, and kitchens. Built with a seamless unibody die-cast frame, it minimizes vibration for smoother airflow while the AC induction motor powers durable steel blades for long-lasting performance.

A variable speed controller is included to fine-tune airflow and noise levels for any application. Dual-ball bearings allow flexible horizontal or vertical mounting, making it a reliable solution for airflow boosting in home ventilation systems.
