The COMBUSTION FRESH AIR DAMPER, Series 'HOM' is motorized and used for the control of fresh air for combustion. It is patented and Code Certified to be field installed and interlocked with a thermostat of a furnace or aqua-stat 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.


Another HMI HOYME damper is the Series 'HAC' AIR CONTROL DAMPER - 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.
