Blower Performance


WS140120S-48-130-X300 blower can reach maximum 44m3/h airflow at 0 kpa pressure and maximum 7kpa static pressure.It has maximum output air power when this blower run at 7kPa resistance if we set 100% PWM, It has maximum efficiency when this blower run at 7kPa resistance if we set 100% PWM.Other load point performance refer to below P-Q curve:

DC brushless blower advantage:


(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 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.

How to use the blower correctly

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.
