14kPa 30CFM 2" inline compact size cooling blower

Suitable for air cushion machine/fuel cell/cooling machine

(1)WS140120S-48-130-X300 blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 10,000hours at 20degree C environmental temperature.

(2)This blower needs no maintence;

(3)This blower drived by a brushless motor controller have many different control functions such as speed regulation,speed pulse output,fast acceleration,brake etc.it can be controlled by intelligent machine and equipment easily.

(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 purify,air bed,cooling,vacuum machine.

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.

Q: What is the MTTF of this centrifugal air blower?

A: MTTF of this centrifugal air blower is 20,000+ hours under 25 C degree.

Motor supply

A DC motor is usually supplied through a split ring commutator as described above. AC motors' commutation can be achieved using either a slip ring commutator or external commutation, can be fixed-speed or variable-speed control type, and can be synchronous or asynchronous type. Universal motors can run on either AC or DC.

Motor control

DC motors can be operated at variable speeds by adjusting the DC voltage applied to the terminals or by using pulse-width modulation (PWM).

AC motors operated at a fixed speed are generally powered directly from the grid or through motor soft starters.

AC motors operated at variable speeds are powered with various power inverter, variable-frequency drive or electronic commutator technologies.

The term electronic commutator is usually associated with self-commutated brushless DC motor and switched reluctance motor applications.
