Nautilair® 8.9” Pre-mix Brushless Blowers

By Patrick Curran | April 23, 2009

Share

Nautilair® 8.9” (225mm) variable speed pre-mix brushless blowers for gas-fired burner systems deliver a measured air/fuel mixture to optimize combustion and reduce nitrous oxide and carbon monoxide emissions. Their brushless DC motor technology enables virtually maintenance-free performance typically exceeding 20,000 hours in a wide range of applications, including commercial and residential boilers, water heaters, furnaces, food service equipment, kilns, and fuel cells, among others.

They can serve as ideal alternatives to conventional fixed 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-efficiency solutions can satisfy a wide range of system designs.

These blowers are available in standard and high-output versions and can achieve maximum sealed pressure capabilities up to 15 in. of H2O and maximum open flows exceeding 550 CFM, depending on model. Versions can accept line voltage input of 120 VAC and 240 VAC (internal electronics convert AC input to DC).

Speed can be adjusted internally with an onboard potentiometer or with an external PWM or DC control that actively varies blower performance (eliminating a need for complex air intake damper systems). Onboard IntelliGen™ controller electronics integrate a factory-programmed digital signal processor (DSP) and add-on expansion cards and other options can be specified to meet particular application requirements.
