Resideo VNT5070H1000 Heat Recovery Ventilator 60Hz 120V

The Resideo VNT5070H1000 Heat Reco Ventilator (HRV) is an efficient system that has been developed to help regulate the air quality inside a home by replacing the old indoor air with the new air from the outside while at the same time preventing loss of heat. Constructed with high-quality steel, this HRV is 120V and 60Hz making it ideal for residential and light commercial applications. The principle that the HRV applies is that it evaporates heat from the old air exiting a room and absorbs heat from the new cold air entering a room and therefore does not require energy to warm or cool the new air.
