Combustion Air Intake Systems
A combustion air system from Grainger helps provide controlled, interlocked combustion air to oil and gas furnaces. A combustion air intake system can replace metal louvers in your commercial or industrial facility. It can duct outdoor air and diffuse it at ceiling level to help eliminate cold spots and disperse warm air more evenly. The commercial combustion air system selections you’ll find here offer inputs ranging from 150,000 to 3,700,000 BtuH. To help improve your furnace’s efficiency, get your combustion air intake system from Grainger.Close
