Variable-speed brushless dc blowers provide high-performance compact solutions for high-output gas-fired burner systems. When used in conjunction with a gas valve and venturi, Nautilair™ pre-mix 12.3-inch blowers deliver a measured air/fuel mixture for optimized combustion and reduced nitrous oxide and carbon monoxide emissions. Typical applications include commercial and residential boilers, water heaters, digital printing equipment, electronic cooling, and industrial processing, among others. The blowers can achieve maximum sealed pressure capabilities up to 20 inches of H2O and maximum open flows to 1,000 cfm, depending on model. Versions can accept line voltage input of 120 vac (1Ø) or 240 vac (1Ø and 3Ø), where internal electronics convert the ac input voltage to dc. Speed can be adjusted internally with an onboard potentiometer or with an external, user-supplied 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. Customized options can be incorporated to optimize blower performance for specific application requirements.
