Tech Drive Super Quiet 110 CFM Bath Fan with Humidity Sensor – No Attic Access, White

Experience quiet, efficient bathroom ventilation

In busy bathrooms, moisture can linger. Tech Drive balances power with whisper-quiet operation, delivering 110 CFM of airflow while keeping sound to a gentle 1.5 sones. This combination helps maintain a comfortable bathroom environment without a loud hum.

Smart humidity control and flexible operation

The built‑in humidity sensor responds to real conditions in your space. In humidity-sensing mode, the fan automatically activates when humidity rises above 60%, helping reduce condensation and keep surfaces drier between showers. If you prefer constant airflow, switch to manual mode for steady, low‑key ventilation.

Safe, flexible installation

Two installation paths cover most homes: a new‑construction route that attaches the fan housing to ceiling joists, and a retrofit option that requires no attic access and can replace most existing bathroom fans from the room ceiling. The low‑profile white grille blends with most ceilings, and the housing measures 9" x 8.5" x 6" with a 4" duct connection, while the ceiling opening is 9.25" x 8.9".

Performance and reliability you can count on

Energy Star qualified and UL and HVI certified, this fan is designed for dependable performance while meeting safety standards. It is suitable for use over a bathtub or shower when installed on a GFCI‑protected circuit. A durable motor is rated for at least 25,000 hours of service, meaning years of quiet operation between replacements.

Real-world use and design details

Perfect for larger bathrooms up to roughly 110 square feet, en‑suites, or master baths where moisture and heat build quickly after showers. The low‑profile grill and white finish provide a clean ceiling look, while the quiet operation helps you carry on daily routines, apply makeup, or unwind after a bath without a disruptive hum.
