New Nautilair™ Series 12.3” variable speed brushless DC blowers introduce high-performance solutions for high-output gas-fired burner systems. These pre-mix blowers have been engineered to deliver a measured air/fuel mixture for optimized combustion and reduced nitrous oxide and carbon monoxide emmissions.
They provide ideal alternatives to conventional fixed speed or two-speed blowers, intake damper systems on fixed speed blowers, or inverter-driven variable speed blowers. Typical applications include commercial and residential boilers, hot water heaters, furnaces, foodservice equipment, kilns, and fuel cells, among others.
The Series 12.3” blowers can achieve maximum sealed pressure capabilities up to 170 in. of H2O and maximum open flows to 800 CFM, depending on model. Versions can accept line voltage input of 120 VAC and 240 VAC and 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). These high-efficiency blowers are designed to operate in excess of 20,000 hours virtually maintenance-free.
Available add-on expansion cards and other options can be incorporated to customize blower performance for specific application requirements.
