High Speed Hvac / Bathroom EC Axial Fan With Variable Speed Control

Hvac Industry Bathroom Exhaust Fan With For Zw400c-230d3-00

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

2.  Currently, both at home and abroad, the EC axial fan has been widely used in various fields, especially     ventilation, large air conditioning and refrigeration. The compact structure and continuous controllability     of EC centrifugal fan has been into full play to air handing units, computer modules, communication            systems ,clean room systems, roof fans, home machine automotive and rail technology

3.   Air heaters, Heat pumps, Condensers, Cooling units, Evapora-tors and Chillers

4.． As the rotor is mounted to interior, the external rotor fan is more compact constructed, smaller and             easy to abstract heat., thus ensure to maximum the reliability of fan operation,

5． Sustainable speed control benefits to achieve low operating costs, reduce CO2 emissions protect the        environment, enable the direct, simple communication between the host controller and the system,

6． Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or                 external circuit impulse modulation

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

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