Electric DC Centrifugal Fan Over Temperature Protection Function 133mm

133mm DC Centrifugal Fan With 48v Fresh Air System PA66 Air Purification

Brushless dc fan use a permanent magnet excitation, eliminate the loss of induction motor excitation currents; realizing the small loss an high

efficiency characteristics

Compared with the frequency control of induction motor, brushless dc ,motor is simpler and more controllable, easy to perform control

The components, such ac inverters etc, whose capacity is low, and circuit are simpler, the cost lower than ec blower’s

OFAN provides the most comprehensive services, includes: product diversification, against the clock delivery, documents support, and technical consulting service. “Customer is partner” is key to our success; ”Win the contract for customer” is our ultimate goal.

Protection: over voltage, over temperature, over current, phase loss detection, communication failure

The basic interface: 0-10V/PWM, RS485/Modbus, 4-20Ma

The basic parameters of field programmable: Maximum speed, minimum speed, maximum power, maximum current,resonance avoid

Constant air pressure controlling function

Embedded design

Electro magnetic compatibility (EMC)

How do I know which model I should choose

Please tell us the fans pressure and ofan and size of fans’ diameter you need. We will study and suggest you the right model.

Can we buy a sample for testing?

Sure, you are welcomed to buy a sample before mass order.

EC Fan Introduction
