The Ametek Windjammer series of compact, variable-speed brushless blowers have been used by NASCAR teams, independent racers, and others for more than 15 years to keep drivers cool during competitive racing events by providing a controlled, cool airstream into their crash helmets. Attributes such as high aerodynamic performance, reliability, functional controllability, all housed in a lightweight package make the blowers suitable for racing programs.
The Windjammer’s various technical features allow its use in many high-reliability applications. A full-wave commutating electronics package enhances its versatility by providing functional performance options, protection features, and increased customization potential.
The blowers are fully programmable so end users do not need to develop their own “hard” control schemes, but can take advantage of a multi-wire input for specific operational functions, including closed loop speed control, maximum speed set, electric braking, current limit, over temperature, locked rotor and others. On-board signal level controllability allows end users to vary the speed (virtually 0 to 100% variation) without any adjustments needed from the main input power supply.
Windjammer blowers are designed to operate at the highest possible aerodynamic efficiencies, lowering their cost of operation and making them better suited for energy efficient or battery operated systems. These units can deliver up to 50 in. (water column) of static pressure and achieve airflow levels of 26 CFM. Blower packages sizes vary from 3.0 to 5.1 in., each providing aerodynamic operating characteristics allowing for a custom fit. All units are powered by Ametek’s 1.7-in. brushless 12 or 24 VDC motor, which features a tachometer output signal as a standard option.
