Certified by CSA International, Hoyme motorized air control dampers, and adapters used to supply Combustion Air for fuel oil, propane and natural gas appliances are reliable and 100% failsafe. The patented Combustion Air Control Damper is a field installed fresh air damper, which interlocks the safety control thermostat of a furnace or aquastat of a boiler. For safety, comfort and efficient fuel consumption, this motorized damper opens to allow fresh air in through an insulated fresh air inlet duct on a call for heat and closes to prevent cold air from migrating in during the off cycle.

Hoyme motorized dampers are manufactured in Alberta and designed for residential and commercial heating and ventilation systems. Ruggedly built, they have proven to withstand the harsh Canadian climatic conditions and with their safety interlocks, restrict operation of the appliance until the damper has proven itself to be in the fully open position. Failsafe and 100% reliable make this the product of choice, eliminating the comfort related problems due to unwanted and uncontrolled air into a home or building.
