Pick-A-Flow® Airflow Technology – One Fan, You Choose The CFM

Built-in, Pick-A-Flow® airflow selector provides the unique ability to select your required airflow (50, 80 or 110 CFM) with the simple flip of a switch. With the flexibility to choose the proper CFM level, you are assured that one fan will satisfy a range of ventilation design requirements and perform, as promised, even with a complicated duct run.

Superior Installed Performance with True Flow ratings at 0.375" w.g.

ASHRAE, ENERGY STAR®, LEED for Homes, and HVI have set the industry standard for performance measurement at 0.1" and 0.25" w.g. WhisperFit DC fans provide powerful CFM airflow at 0.375" w.g. that is more representative of most installations. Sones have also been certified at 0.25 w.g. to provide a more realistic, installed value.
