Variable Speed Brushless dc Blowers

Nautilair variable speed brushless dc blowers deliver a measured air/fuel mixture in gas-fired burner systems for better combustion and reduced nitrous oxide and carbon monoxide emissions. These pre-mix burner blowers offer practical solutions for a range of applications, including commercial and residential boilers, hot water heaters, furnaces, foodservice equipment, kilns, and fuel cells, and more.

Speed can be adjusted internally with an onboard potentiometer or with an external PWM or dc control that actively varies blower performance. This eliminates the need for complex air intake damper systems; internal electronics convert ac input to dc; and blowers typically operate in excess of 20,000 hours virtually maintenance-free.

The blowers come in three series (7.6 in., 8.0 in., and 8.9 in.) and accept line voltage input of 120 Vac and 240 Vac, depending on model. Maximum sealed pressure to 45 in. of H2O and maximum open flows to 875 CFM.
