Fantech VHR Series Heat Recovery Ventilator w/ Recirculation Defrost, 6" Top Ports (up to 3,600 Sq. Ft.)

A Heat Recovery Ventilator is a complete whole house ventilation system that incorporates a supply motor and an exhaust motor in one unit. It is designed to bring a continuous supply of fresh air into the home while exhausting an equal amount of contaminated air. HRVs use what is known as a "sensible" heat recovery core. The special aluminum core transfers heat from the exhaust air stream to the incoming air stream. Fresh incoming air is tempered by the heat that is transferred from the outgoing air so you save on energy costs. HRVs are designed for colder areas of the country that have longer heating seasons as well as drier desert areas of the South.
