In this video, Jeffrey Anzevino of AMETEK shows off the company’s motorized air/fluid motion products including the Windjammer, Nautilair, and ROTRON product brands.
Windjammer and Nautilair motors, blowers, and pumps are variable speed and electronically commutated. A wide range of physical sizes, input power choices and other design features are available. For instance, the smallest blower is 3 inches in diameter and largest is 12.3 inches. Options for power sources run the range from 12 or 24VDC to 100, 120 or 240 VAC.
The Rotron product line consists of variable speed, electronically commutated DC motors, fans and pumps. They’re designed for 40,000 to 60,000 hours of operating life and for use in harsh environments. Motor products range from 3 to 5.75 inches while the fan products range from 10 to 16 inches in diameter. The pump products have airflow rates from 10 to 26 gallons/minute.
Also in the Rotron product line are industrial regenerative or side channel blowers driven by AC induction motors, with power ranges from 1/16 hp to 60 hp. Accessories can include air flow switches, air flow meters, air filters, relief valves, mufflers, diverters and gauges.

Windjammer® variable-speed, brushless DC blowers offer compact, low noise, and long life solutions. The extensive standard product line includes low voltage and high voltage (bypass and thru-flow) versions to satisfy the widest range of blower application requirements.
All Windjammer brushless blowers feature compact design with diameters of 5.7 in. (145mm). Their engineering promotes long life and virtually maintenance-free operation. Speed can be adjusted internally with an onboard potentiometer or with an external PWM or DC control that actively varies blower performance.
Among options, an IntelliGen™ electronic control drive integrating a factory-programmed digital signal processor (DSP) and custom option cards can be incorporated to meet specific application demands.
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 burner blowers offer practical solutions for a wide range of applications, including commercial and residential boilers, hot water heaters, furnaces, foodservice equipment, kilns, and fuel cells, among others.
They 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-speed blowers can suit a wide range of system designs.
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); 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 four series (7.6”, 8.0”, 8.9”, 12.3”) and blowers accept line voltage input of 120 VAC and 240 VAC, depending on model.
Among options, an IntelliGen™ electronic control drive integrating a factory-programmed digital signal processor (DSP) and custom option cards can customize performance for specific application requirements.
AMETEK ROTRON® line of regenerative blowers are designed based on the regenerative principle. The impeller blades passing the inlet port of the blower draw air or other gasses into the blower. The impeller blades then, by centrifugal action, accelerate the air outward and forward. Here the “regenerative” principle takes effect as the air is turned back by the annular shaped housing to the base of the following blades where it is again hurled outward. Each “regeneration” imparts more pressure to the air. When the air reaches the stripper section at the outlet (the stripper is the part of the blower located between the inlet and the outlet in which the annulus is reduced in size to fit closely to the sides and tips of the impeller blades) the air is “stripped” from the impeller and diverted out of the blower. The pressures or vacuums generated by the one or two spinning, non-contacting, oil-free impellers are equal to those obtained by many larger multi-stage or positive displacement blowers.
Regenerative blowers are available in many configurations designed to meet specific applications.
