What is the difference between AC cross flow fan and DC cross flow fans ?
– DC Fan Motors Efficiency about 30% less energy than AC fans – Quieter operation whhich is low to 19 dBA level . – Suitable for extreme temperature environments ; – Provides more variable, uneven airflow,Minimal electromagnetic interference – Low voltage operation– Integrated PCB control system .

FAQ :
Q1. what’s the advantages of your cross flow fan ? -LONGWELL cross flow is special design for low noise purpose only . noise even low to 19 dBA ; – We have large production range from 20mm to 200mm ; – We have heavy duty design which makes 4000rpm for diameter less 60mm，150mm dia fan makes over 2700rpm.
Q2. Does Longwell provide any speed control options for DC cooling fans ?
Reply : Yes , Longwell can provide some speed regulator solutions according customer’s requirements ,such as : – The 0-10V/ pwm controller is for use with the full range of cross flow fans / dc cooling fans. Powered by the 10VDC 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 .
Q3. how we connect the tangential fan to our application ,is there a wiring diagram ?
Reply :
Please check the speed control of your application first ( is it PWM or 0-10V ) , Please refer to the wiring diagram of 0-10v series as below :
