48V 130mm dust extractor high speed centrifugal radial blower fan with brushless motor for 24v dc exhaust fan and centrifugal duct fan.

Suitable for vacuum machine/fuel cell/medical equipment and inflatables.

(1)WS130120S2-48-220-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 15,000hours 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 vacuum machine,dust collector,floor treatment 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: Are you factory or trading company?

A: We are factory with 4,000 square meters and we have been focus on high pressure BLDC blowers for more than 10 years

Q: Can we connect this centrifugal air blower directly onto power source?

A: This blower fan is with BLDC motor inside and it needs a controller board to run.

How Electric Motors Work

A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source. Brushed motors were the first commercially important application of electric power to driving mechanical energy, and DC distribution systems were used for more than 100 years to operate motors in commercial and industrial buildings. Brushed DC motors can be varied in speed by changing the operating voltage or the strength of the magnetic field. Depending on the connections of the field to the power supply, the speed and torque characteristics of a brushed motor can be altered to provide steady speed or speed inversely proportional to the mechanical load. Brushed motors continue to be used for electrical propulsion, cranes, paper machines and steel rolling mills. Since the brushes wear down and require replacement, brushless DC motors using power electronic devices have displaced brushed motors from many applications.

We have been operating every production process in a standardized manner to ensure the excellent quality of our 140mm Waterproof IP55 Fan Ec-DC Single Inlet Blower Fan. Through strict management procedures, we provide customers with error free high quality service. We guide our employees to combine their career goals with the company's vision, to focus on service and dedication, and to realize their personal self-worth.
