Put A Damper On Cold Air

The Hoyme "HAC" model universal air control damper is an effective damper to control incoming air into homes in both a hot and a cold climate. Your home heating or cooling system fully controls the Hoyme damper to safely and efficiently supply fresh air for your comfort. During hot summer months the hot daytime air is kept out of the home , so the air conditioner doesn't have to work as hard and during cold winter months the cold air is only allowed in the home when the furnace is operating. Therefore the furnace doesn't have to work as long or as hard. Hoyme HAC model air control dampers come with a mounting collar which allows easy installation to your return plenum or without the collar for mounting inline. The HAC model damper is equally effective in providing significant energy savings for both a standard furnace and a high efficiency furnace

The Hoyme HACmodel w/ relay is a stand alone damper with it's own relay. This damper is used when a Hoyme "HOM" model is not required.
