Variable Speed Blowers

Nautilair 7.6-in. (192 mm) variable speed blowers for gas-fired burner systems incorporate brush less dc motors to provide reliable performance in excess of 20,000 hours with minimal maintenance, according to the company. These premix burner blowers are designed to deliver a measured air/fuel mixture to optimize combustion and reduce nitrogen oxide and carbon monoxide emissions. Applications include commercial and residential boilers, water heaters, furnaces, foodservices equipment, kilns, and fuel cells, among others. They offer practical alternatives to conventional fixed speed or two-speed blowers, intake damper systems on fixed speed blowers, or inverter-driven variable speed blowers. The blowers accept line voltage input of 12 V dc, 24 V dc, 120 V ac, and 240 V ac, depending on model, and internal electronics convert ac input to dc. Maximum sealed pressure capabilities up to 45 in. of H2Oand maximum open flows exceeding 160 cfm can be achieved.
