FAQs
Life span of this kind of Centrifugal fans ?
Longwell EC external rotor motor surpasses efficiency class IE4, magnets with no rare earths, maintenance-free ball bearings (sealed) with long-term lubrication, theoretical nominal service life of at least 40,000 hours of operation, installation with horizontal and vertical motor shaft; soft start, integrated current limitation. Integrated electronics, quiet commutation logic; 100 % speed controllable; control signal 0-10 V DC / PWM; tach output.
Why the Ec centrifugal fan is much efficiency than Ac centrifugal fan ?
– Longwell EC fans always operate in the correct direction ; Operate on either 50Hz or 60Hz; Operate on a wide voltage range(200-277Vsingle Phase&380-480 Vthree phase ); Operates much cooler-longer life ; Less heat for a refrigeration system to handle (increased refrigeration COP),30 % average energy saving compared to AC technology ;
Does Longwell provide any speed control options for EC FANS ?
Yes , Longwell can provide some speed regulator solutions according customer’s reguirements such as .The RM-ECi controller is for use with the full range of ebm-papst EC fans. Powered by the 10VDC output fromthe motor, it provides infinitely variable, manual speed control between 0% and 100%Can control multiple fans running at the same speed – Stepless control knob for infinitely variable speed setting – Cable entries 4xM16 or M20 – 4mm mounting holes
how we connect fan unit to our application ,is there a wiring diagram ?
Please check the speed control of your application first ( is it PWM or 0-10V , LONGWELL’s all series of Centrifugal fans support 0-10V or PWM and RS485 internet Protocol )for more details please contact us for professional engineer service
Are there any other AC DC EC centrifugal fans options or solutions for selection ?
Yes ,sure . LONGWELL is a professional manufacturer of fans, blowers , motors and components for heating ,venlation, air conditioner and refrigeration applications ,specialist in centrifugal fans, axial fans, AC /BLDC cross flow fans, single / double forward curved fan BLOWERS ,AC / BLDC/ECM motors as well as industrial fan blowers, inline duct fans , Poultry ventilation fans ( AC / DC /EC ) , etc.
