Design Features:


Microjammer® variable-speed, brushless DC blowers have been newly engineered for increased life, reduced vibration, and improved performance. These low-voltage, 12/24VDC blowers serve ideally in a wide range of medical and industrial applications, including respiratory equipment, cooling systems, and air sampling equipment, among others.

Their redesigned bearing system contributes to longer life and a rear-balancing disk significantly reduces vibration of the blower’s rotating fan system. Both features have been incorporated as standard in the 5.1 in. (130mm) blower and can be specified for blowers in sizes 3.0 in. (76mm), 3.3 in. (84mm), and 4.5 in. (114mm).

Microjammer 3.0, 3.3, and 4.5 in. blower designs further integrate a next-generation ½ wave (uni-polar) electronic controller into the motor to enable compact and improved 2-wire operation. Optional 8-wire configuration for connection to external, full wave (bi-polar) electronic controllers can also be ordered.

Additional options include an FPS (frequency pulse signal) for speed tach output and a separate V+ signal wire for input power to Hall sensors to extend low-speed operation.
