Vents GK 125 MA Bathroom Exhaust Fan Kit
The Vents GK 125 MA Bathroom Exhaust Fan Kit delivers powerful, energy-efficient ventilation for bathrooms, laundry rooms, and utility spaces. Upgraded from the Vents GK 125 LD model, it features enhanced airflow (up to 102 CFM) and built-in backdraft prevention shutters that remove excess moisture, eliminate odors, and help improve indoor air quality.
Easy Through-Wall Installation
Designed for simple installation, this bathroom exhaust fan kit mounts directly through the wall using the included PVC sleeve and exterior grille. It fits wall thicknesses from 4 to 11.5 inches and includes a corded plug for flexible setup-either hardwire it or plug it into a standard wall outlet.
Compact, Quiet, and Reliable
With a 5-inch duct diameter and compact body (7-½ W × 7-½ H × 3-7/8 L inches), the Vents GK 125 MA is ideal for bathrooms, laundry areas, and other moisture-prone rooms. Operating at just 2.6 sones, it delivers quiet, effective performance while preventing backdrafts with an internal damper. (Not suitable for shower enclosures.)
