Product Name: Plastic/metal Fan Impeller/Blade/Wheel for Centrifugal/Exhaust Model NO.: 77-121 Certification: RoHS, CE, CCC Mounting: Air Conditioner Fan Electric Current Type: AC Type: Axial Fan Blade Material: Plastic Material: Plastic Color: Customized Area: HVAC Parameter: Customized Trademark: Royals Technology Transport Package: Wooden Box Origin: Qingdao Product Description Production Description:RoyalS Technology fan products include DC fan, EC fan, thin centrifugal fan and fan array. The design focuses on its high reliability and long product life, with low-noise, high-efficiency, eco-friendly and energy-saving qualities. We can design fans according to different demands from our clients, and they will endure in harsh environmental requirements..Feature:Low vibrationEnergy savingAcoustic DesignAerodynamic designLow vibration: The Royals Technology fan impeller is a cutting edge measurement tool for non-contact measurement, visualization and analysis of structural vibrations. It determines the operational deflection shapes and Eigen modes as easily as taking a photograph. Entire surfaces can be scanned and probed automatically using flexible and interactive measurement grids. Measurements can be made over a wide frequency bandwidth.Energy saving: Royals Technology team is in contorl of the relevant motor design parameter. By changing the parameter of stators and and motots and magnetic properties, the motor output can be obtained through precise calculation, such as magnetic flux density, torque, core loss and copper loss. This allows us to understand the effect of relevant design parameters to the motor efficiency.Acoustic Design:Aerodynamic design:Specification and Parameters:
