Combustion Air Intake Systems

Tjernlund combustion air intake systems provide controlled volume of outside air for proper combustion in oil & gas heating appliances, while eliminating the need for louvered openings. Raptor Supplies offers a wide range of combustion air intake vent systems which use indoor air to temper outdoor air for more comfort. They feature a damper that closes during off cycles to cut off cold air coming in & reduce warm air loss. These systems are also called gas furnace combustion air intake systems as they replace air vented out by fireplaces & exhaust fans.
