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.Certification: ce, RoHS, ETL Warranty: 1 Year After-sales Service Provided: Online support Life time(MTTF): >20,000hours (under 25 degree C) Weight: 80grams Housing material:PC Unit size: D70mm *H37mm Motor type:Three Phase DC Brushless Motor Outlet diameter: OD17mm ID12mm Controller: external Static pressure: 6.8kPaBrand name: Wonsmart High pressure with dc brushless motor Blower type: Centrifugal fan Voltage: 24vdc Bearing: NMB ball bearing Type: Centrifugal Fan Applicable Industries: Manufacturing Plant Electric Current Type: DC Blade Material: plastic Mounting: Ceiling Fan Place of Origin:Zhejiang, China Voltage:24VDCWS7040-24-V200 blower can reach maximum 22m3/h airflow at 0 kpa pressure and maximum 6.8kpa static pressure. It has maximum output air power when this blower run at 3kPa resistance if we set 100% PWM.

Motors that directly produce linear motion are called linear motors. The advantage of linear motors is that they can produce linear motion without the need of a transmission system, such as ballscrews, leadscrew, rack-and-pinion, cam, gears or belts, that would be necessary for rotary motors. Transmission systems are known to introduce less responsiveness and reduced accuracy. Direct drive, brushless DC linear motors consist of a slotted stator with magnetic teeth and a moving actuator, which has permanent magnets and coil windings. To obtain linear motion, a motor controller excites the coil windings in the actuator causing an interaction of the magnetic fields resulting in linear motion.Tubular linear motors are another form of linear motor design operated in a similar way.
