Constant torque ,constant speed and constant airflow of EC fan can be fulfilled via 180,sine SVPWM(Space Vector PWM)to meet customer needs

Intelligent EC fan can support users to realize centralized operation control by 485 bus and monitor as many as 255 fans

EC fan has comprehensive protection function, such as phase failure, overvoltage, undervoltage, locked-rotor, over current and temperature protection

Protection: over voltage, over temperature, over current, phase loss detection, communication failures.

The basic interface: 0-10V/PWM, RS485/Modbus, 4-20Ma




How do I know which model I should choose

Please tell us the fans pressure and ofan and size of fans’ diameter you need. We will study and suggest you the right model.

Can we buy a sample for testing?
