(4) Drived by brushless motor driver the blower will have over current, under/over voltage,stall protections.

This blower can be widely used onto air pollution detector,air bed,air cushion machine and ventilators.

This blower can run at CCW direction only.Reverse the impeller running direction can not change the air direction.

Filter onto the inlet to protect the blower from dust and water.

Keep the environmental temperature as low as possible to make the blower life time longer.

Q: Do you also sell controller board for this blower fan?

A: Yes, we can supply adapted controller board for this blower fan.

Q: How to change impeller speed if we use your controller board?

A: You can use 0~5v or PWM to change speed. Our standard controller board is also with a potentiometer to change speed conveniently.

The brushed DC electric motor generates torque directly from DC power supplied to the motor by using internal commutation, stationary permanent magnets, and rotating electrical magnets. Brushes and springs carry the electric current from the commutator to the spinning wire windings of the rotor inside the motor. Brushless DC motors use a rotating permanent magnet in the rotor, and stationary electrical magnets on the motor housing. A motor controller converts DC to AC. This design is simpler than that of brushed motors because it eliminates the complication of transferring power from outside the motor to the spinning rotor. An example of a brushless, synchronous DC motor is a stepper motor which can divide a full rotation into a large number of steps.
