SoffitFlow 4-Inch Soffit Vent for Bathroom Fan Exhaust

• 4-Inch Diameter Collar (Rear-Mounted): Strategically positioned at the rear of the housing, this collar works with a precision-tapered bottom panel to optimize airflow and channel exhaust efficiently in one direction. • Integrated Weep Hole: Prevents water buildup from condensation by allowing it to drain outside in the form of a drip. • Angled Gravity Damper: Automatically opens at 50 CFM or greater, ensuring compatibility with most standard bathroom exhaust fans (50–110 CFM). The damper closes when airflow stops to prevent backdrafts and improve energy efficiency. • Extended Nose Design: The vent’s nose projects beyond the fascia, ensuring humid air is directed away from the roofline — reducing the risk of moisture re-entering attic spaces. • Front Hinged Grill: Keeps wildlife out of your ductwork and opens easily for maintenance and cleaning. • Durable HDPE Construction: Engineered to withstand long-term sunlight exposure without becoming brittle. Its chemical resistance also protects against acids, oxidants, and harsh solvents. • Low-Profile Finish: With sleek lines and a discreet look, SoffitFlow blends seamlessly into any exterior while delivering high-performance ventilation.
