HOM - Combustion Fresh Air Damper (General Damper Identification: i.e HOM-0511-SF1)

Series HOM - Hoyme motorized air control dampers and adaptors used for combustion air are certified by the Canadian Standards Association International (CSA) which includes the U.S and Canada. The patented Combustion Air Control Damper is a field installed fresh air damper which interlocks with the thermostat of a furnace or aquastat of a boiler, using either oil, propane or natural gas. The damper is placed at the terminating end of an insulated fresh air inlet duct beside the furnace. When the thermostat asks for heat, this motorized damper opens to allow fresh air for complete combustion. When the furnace stops, the damper closes to prevent the entry of unnecessary cold air. This results in added comfort with a definite saving of fuel.

HAC - Series Air Control Damper

Motors - 24VAC, CSA International Certified. Satisfaction guaranteed.

These dampers are placed in-line and are used for FRESH AIR VENTILATION and ZONE AIR CONTROL. When used for ventilation, any exhaust fan turned on will open the fresh air damper and thus fresh air is brought in to replace air being exhausted. When used for zone air control, a thermostat in each room will open the damper for proper air flow to that room.

'In-Line' type motorized damper to control Replacement, Make-up, Ventilation and Zone Air for Residential and Commercial buildings.
