    Blower Performance

    WS9290B-24-220-X300 blower can reach maximum 38m3/h airflow at 0 kpa pressure and maximum 13kpa 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)WS9290B-24-220-X300blower is with brushless motors and NMB ball bearings inside which indicates very long life time; MTTF of this blower can reach more than 20,000hours 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 air pollution detector,air bed,air cushion machine and ventilators.

    How to Use the Blower Correctly



    Q: When can I get the price?

    Q: How long is your delivery time?

    A: The general delivery time is 30-45 days after receiving your order confirmation. Anther, if we have the goods in stock, it will only take 1-2 days.

    How to Choose Brushless DC Motor?

    How do I choose a brushless DC motor suitable for me?

    Let’s look at one example: A few days ago, a customer sent such technical requirements: Yesterday, the boss changed the parameters.

    We need to make a transport car:

    1.High speed Vmax > 7.2km/h

    2.The maximum gradient is 10% (0.9km/h)

    3.Acceleration time: less than 12 S (0-7.2 km/h)

    4.Full load mass (kg):600 kg

    5.Wheel diameter: 100mm

    What Is Your Matching Motor Drive And Reducer?

    These are more complex calculation methods. The power of the brushless DC motor that the customer needs to choose is 70W calculated by himself, and the power calculated by us is about 100w. We suggest that the customer choose 120W brushless DC motor. This is our choice according to the experience of DC brushless DC motor for AGV car industry. Yes. Leaving more power margin for practical application is a basic principle for us to choose the motor, so that even in practical use, beyond the design limit, the DC brushless motor can meet the requirements. This is chosen from the angle of protecting brushless DC motor and design experience.

    There is no perfect motor, only perfect match
