This variable-speed blower offers precise airflow control with its infinitely adjustable CFM setting, preventing over-ventilation and maximizing energy efficiency. Its DC motor exceeds ENERGY STAR requirements and is designed for continuous operation. The adjustable time delay allows you to set how long the fan runs on high speed before switching to a lower continuous speed, ensuring optimal performance. Ideal for meeting ASHRAE 62.2, LEED, ENERGY STAR, and CA Title 24 standards, it also suits local and spot ventilation needs.
