The AK Bath Fan 0.5 Sone 50 CFM delivers powerful, energy-efficient ventilation with whisper-quiet performance. Engineered for bathrooms and powder rooms up to 65 sq. ft., this ceiling-mounted exhaust fan moves 50 CFM of air at just 0.5 sones—ideal for keeping moisture and odors under control without disruptive noise. Its ENERGY STAR®-qualified motor and high-impact plastic housing resist rust and vibration, ensuring years of reliable, nearly silent operation.

Installation is fast and foolproof thanks to the patented snap-in mounting system. Simply fasten the included bracket to a ceiling joist, “snap” the fan housing into place, connect wiring and ductwork, and attach the grille—no attic access or complex framing required. A 4″ duct collar with built-in backdraft damper prevents drafts and further reduces sound, while continuous-run capability and industry certifications (HVI 2100, CULus, UL for tub/shower, Title 24, ASHRAE 62.2) give you confidence in performance and compliance.
