AeroPure ABFS110DCMH G5 50/80/110 CFM Slim Fit Continuous Run Bathroom Exhaust Fan | Motion, Humidity & Timer Sensors | Square Grille

The AeroPure ABFS110DCMH G5 is the slim-fit ABF series equivalent of the VSF110DCMH-S — a continuous run DC motor exhaust fan with motion sensing, humidity sensing, and a built-in timer, all in a slim-fit housing with a square grille. It's the most intelligent and automated fan in the ABF lineup.

Like the VSF110DCMH-S, it runs at a continuous low background speed to maintain baseline ventilation at all times. When the motion sensor detects someone entering the bathroom, the fan kicks up automatically to your pre-set high CFM setting (50, 80, or 110 CFM via the Flex CFM™ adjustable switch). The humidity sensor provides an independent second trigger — if moisture levels rise above your set threshold (50–100% RH, user adjustable), the fan ramps up regardless of motion detection and continues running until the air clears.

Energy Star qualified, ETL listed for tub/shower use with GFCI wiring, and rated for IC insulated ceiling installation.

Requires two switches for installation — see wiring diagram for details.
