EASY UPGRADES

Find that your 50 CFM unit is not cutting it? No need to uninstall the whole unit; our Contractor Series features interchangeable motor kits, making upgrades simple and easy with their plug-in motors. 

PERFECT FOR NEW CONSTRUCTION

Contractor series units can be installed in a 2-phase system—the housing can be mounted with wiring and duct in one phase, and the blower and grille installed in a later second phase later once the ceiling is complete. Keyhole mounting tabs, removable wiring compartments, and removable blowers with plug-in motors make setup quick and easy. 

CREATE A HEALTHY HOME

A warm shower is great, but all that unventilated steam and moisture can set up your bathroom for mold and mildew (and the damaging after-effects of removing it). Installing a Contractor Series bath fan aids in removing this moisture in bathrooms ranging from 45 - 65 sq. ft.
