Centrifugal Fan Product Introduction

This series of centrifugal fans uses AC capacitors to operate asynchronous motors, which are divided into two categories: inner rotor and external transmitter. The fan has two modes of speed control, which is controlled by thyristor stepless speed regulation and motor winding tapping. The conventional three-speed adjustment Speed; The use of advanced technology to design the fan, with the advantages of convenient installation, reliable operation, low noise, large air volume, energy saving and high efficiency; using years of research and development technology of motor production, eliminate the AC electromagnetic noise generated during the operation of the motor, superior to similar products. ; Has the advantage of cheap high quality.

This series of centrifugal fans is mainly used for ventilation and air exchange of various equipment such as FFU air filter unit, air purifier, and air conditioner outside machine.

Voltage: Single AC 220V/50HZ, can customize the motor with different voltage and frequency. According to customer needs can be customized fourth gear, five gear, speed motor.

Centrifugal fan rated air flow from 200 to 4000m3/h.

The motor output power ranges from 5W to 200W micromotors.

Motor insulation grade B, F, internal 125-135 °C thermal protector.

The average service life of the motor is more than 30,000 hours. Work mode: S1.

Motor applicable ambient temperature: -30 °C ~ 60 °C.

The motor passed the European CE certification and China's CCC certification.

Before the motor is used, the motor ground wire must be effectively connected to the external grounding device.
