    Blower Performance

    WS4540-24-NZ01 blower can reach maximum 7.5m3/h airflow at 0 kpa pressure and maximum 4.8 kpa 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 3.5kPa resistance if we set 100% PWM. Other load point performance refer to below P-Q curve:


    DC Brushless Blower Advantage

    (1)WS4540-24-NZ01 blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 30,000hours at 20degree C environmental temperature

    (2)This blower needs no maintenance

    (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 CPAP machine and air pollution detector.

    How to Use the Blower Correctly

    (1)This blower can run at CCW direction only.Reverse the impeller running direction can not change the air direction.

    (2)Filter onto the inlet to protect the blower from dust and water.

    (3)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: May I use this blower for Medical device?

    A: Yes, this is one blower of our company which can be used on Cpap.

    Q: What’s is the maxmum air pressure?

    A:  As it shown in the drawing, the maxmum air pressure is 5 Kpa.

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

    A: MTTF of this centrifugal air blower is 10,000+ hours under 25 C degree.

    The centrifugal design uses the centrifugal force generated by a rotating disk, with blades mounted at right angles to the disk, to impart movement to the air or gas and increase its pressure. The assembly of the hub, disk and blades is known as the fan wheel, and often includes other components with aerodynamic or structural functions. The centrifugal fan wheel is typically contained within a scroll-shaped fan housing, resembling the shell of the nautilus sea creature with a central hole. The air or gas inside the spinning fan is thrown off the outside of the wheel, to an outlet at the housing's largest diameter. This simultaneously draws more air or gas into the wheel through the central hole . Inlet and outlet ducting are often attached to the fan's housing, to supply and/or exhaust the air or gas to the industry's requirements.

    There are many varieties of centrifugal fans, which may have fan wheels that range from less than 3 cm to over 16 feet (5 m) in diameter.
