Continuous Ventilation and Duct Boosting
Spruce Continuous Ventilation & Duct Boosting Mechanical ventilation is often necessary to assure better indoor air quality in today's tightly sealed homes and commercial buildings. A Spruce inline fan enhances air quality with continuous ventilation, which reduces point 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. Spruce inline fans are ideal for ventilating a new addition and/or for improving the efficiency of an existing air system. 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. Spruce offers two convenient Duct Boosting Kits featuring interior mount, lightweight, durable construction and are rated for continuous operation. The SDB110P kit (P/N 28131) includes the RB110 fan (named a 2017 Most Efficient product by Energy Star®), an air pressure-sensing switch, probe, and vinyl tubing. The SDB110C kit (P/N 28259) also includes the RB110 fan plus an A/C current-sensing switch. See below for RB110 fan features and specifications.
