Spruce 9.7-Inches dia 158 CFM ABS plastic Axial duct fan

This fan kit includes: a fan, mounting bracket, and air current sensing switch. Duct boosting will give an old heating and cooling system the lift necessary to get conditioned air into newly expanded living or working areas as well as any other areas where it is needed. Mechanical ventilation is often necessary to assure better indoor air quality in today’s tightly sealed homes and commercial buildings. Our fan enhances air quality and helps to meet indoor air quality requirements with continuous ventilation, which reduces source pollutants in a variety of home and business settings, including workshops, hobby rooms, smoking rooms and other indoor spaces where pollutants enter the air.
