Blower Performance
WS7040-12-X200 blower can reach maximum 18m3/h airflow at 0 kpa pressure and maximum 5.5kpa static pressure. It has maximum output air power when this blower run at 3kPa resistance if we set 100% PWM. It has maximum efficiency when this blower run at 5.5kPa resistance if we set 100% PWM. Other load point performance refer to below P-Q curve:

DC brushless blower advantage
(1)WS7040-12-X200 blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 20,000 hours at 20 degree 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 cushion machine, CPAP machine, SMD soldering rework station.
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 lifetime longer.
What Is Centrifugal Fan?
A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink; such a fan is also called a blower, blower fan, biscuit blower, or squirrel-cage fan (because it looks like a hamster wheel). These fans increase the speed and volume of an air stream with the rotating impellers.
FAQ:
Q: May I use this blower for Medical device?
A: Yes, this is one blower of our company which can be used on Cpap and ventilator.
Q: What is the maxmum air pressure?
A: As it shown in the drawing, the maxmum air pressure is 6 Kpa.
Brushless motors are commonly used as pump, fan and spindle drives in adjustable or variable speed applications as they are capable of developing high torque with good speed response. In addition, they can be easily automated for remote control. Due to their construction, they have good thermal characteristics and high energy efficiency. To obtain a variable speed response, brushless motors operate in an electromechanical system that includes an electronic motor controller and a rotor position feedback sensor.
Brushless DC motors are widely used as servomotors for machine tool servo drives. Servomotors are used for mechanical displacement, positioning or precision motion control. DC stepper motors can also be used as servomotors; however, since they are operated with open loop control, they typically exhibit torque pulsations.Brushless DC motors are more suitable as servomotors since their precise motion is based upon a closed loop control system that provides tightly controlled and stable operation.
