Ventline 75cfm 120V lighted bath fan with damper and side exhaust. Measures 11" diameter. Replaces standard 50cfm V2280-50 and 60cfm V2245-60 for more air flow. This can also replace the non-lighted V2270-75 fan by making the opening in the ceiling slightly bigger. Also requires a few more inches of room up inside ceiling. Connects to 3" flexible ductwork.
