Ametek’s Nautilair variable-speed, brushless DC blowers deliver a measured air/fuel mixture in gas-fired burner systems for optimized combustion and reduced nitrous oxide and carbon dioxide emissions. They serve as alternatives to fixed speed or inverter-driven variable speed blowers. Speed can be adjusted internally with an onboard potentiometer or with an external PWM or DC control.  The blowers are available in 7.6-, 8.0- and 8.9-in. versions with voltage inputs of 120 or 240 VAC. Maximum sealed pressure capabilities up to 45 in. (water) and maximum open flows of 875 cfm are possible.
