AMETEK DFS Nautilair Products
  • Overview +


    Nautilair variable speed brushless DC blowers have been engineered to deliver a measured air/fuel mixture in gas-fired burner systems for optimized combustion and reduced nitrous oxide and carbon monoxide emissions. These pre-mix blowers offer practical solutions for a wide range of applications, including commercial and residential boilers food service equipment, kilns, and fuel cells, among others.

    They serve as ideal alternatives to conventional speed or two-speed blowers, intake damper systems on fixed speed blowers, or inverter-driven variable speed blowers. When used with a modulating gas valve, these compact, lightweight, rugged, versatile, and high-speed blowers can suit a wide range of system designs. 

    Speed can be adjusted internally with an on board potentiometer or with an external PWM or DC control that actively varies blower performance (eliminating a 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 product line is available in 3 series: 7.6", 8.9", 12.3" and these blowers accept line voltage inputs of 120VAC, 240VAC and 12-24VDC depending on the model.

    Among options, an Intelligen II electronic control drive integrating a factory-programmed digital signal processor (DSP) and custom option cards can customize performance for specific application requirements.
