Introducing the NEW SER series of Energy Recovery Ventilators (ERV) by Fantech. As with previous designs, incoming fresh outdoor air is filtered before it is heated by the stale outgoing air through an enthalpy energy recovery core. The ERV then distributes the fresh filtered air throughout the home by direct ductwork installed specifically for the ERV or through the ductwork of a forced-air system.

The climate conditions where you live will determine whether you need a Heat Recovery Ventilator or an Energy Recovery Ventilator. HRV's are usually recommended for colder climates with longer heating seasons. ERV's are used for warmer, more humid climates with long cooling seasons. Please see our helpful reference map to assist in selecting the right unit for you.
