Featuring a direct-drive motor, this fan has 73 airflow positions and a number of speeds to provide users with circulation whether it’s down an aisle or assembly line, around obstructions, or in spaces with low-hanging ceilings.

When space restrictions prevent the use of in-line duct fans, this product can be as little as 4 inches, providing room to connect appropriate ductwork.

The KRD Radial Blade Blowers are precision, balanced air-moving packages that feature a compact design and heavy-duty welded steel housing and motor base. The self-cleaning, cast aluminum wheels are ideal for exhaust systems where air is laden with dirt, lint, or foreign materials.

This electronically commutated motor (ECM) direct-drive fan option is available for use with the Aero® 39M commercial air handler.

CF Bathroom Exhaust Fans are available as complete fan assemblies and come in easy-to-install contractor packages. The units are designed to fit 3- and 4-inch duct sizes and include a built-in damper that prevents backdraft, keeping tempered air in the home when the fan is not operating.
