| Blower Performance |
WS140120S-48-130-X300 blower can reach maximum 88m3/h airflow at 0 kpa pressure and maximum 15kpa 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 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.
| Applications |
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.
| FAQ: |
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.
The application of brushless DC motors within industrial engineering primarily focuses on manufacturing engineering or industrial automation design. In manufacturing, brushless motors are primarily used for motion control, positioning or actuation systems.
Brushless motors are ideally suited for manufacturing applications because of their high power density, good speed-torque characteristics, high efficiency, wide speed ranges and low maintenance. The most common uses of brushless DC motors in industrial engineering are linear motors, servomotors, actuators for industrial robots, extruder drive motors and feed drives for CNC machine tools.
