Nautilair 7.6 in (192) mm Variable Speed Blowers

Product Announcement from Ametek Dynamic Fluid Solutions

Nautilair 7.6-in. (192 mm) variable speed blowers for gas-fired burner

systems incorporate brushless 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, foodservice 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.
