Fantech Heat Recovery Ventilator VHR-704 is a complete whole house ventilation system that incorporates a supply motor and an exhaust motor in one unit. Fantech VHR-704 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. With the single speed fan - you need no other controls other than on or off.

The Fantech Heat Recovery Ventilator VHR 704 is designed for houses up to 1,400 Square feet. HRVs are designed for colder areas of the country that have longer heating seasons as well as drier desert areas of the South.
