      Shop a selection of gas fired duct furnaces at Grainger. They are suitable for HVAC equipment rooms, manufacturing facilities, automotive garages, greenhouses, dusty, dirty or mildly corrosive environments, or applications where slightly negative pressure exists. Models with 409 stainless steel hat exchangers are recommended when incoming air is below 40 degrees F and/or units are located downstream from cooling coils.
