AC Variable Frequency Motor Inverter Drives for Clean Room Fan

A clean room is virtually dust and/or bacteria free. Clean rooms are used in laboratory work and in assembly or repair of precision equipment. A clean room fan supplies clean air through ventilation systems. This fan runs a system that filters exterior air, maintains temperature and humidity at constant levels, and circulates the interior air through a high-performance air filter while expelling part of the interior air.

Application Challenges

  • Maintain positive pressure in the clean room.
  • Maintain a high quality filtering system at all times.
  • Avoid mechanical resonance in the surrounding equipment.
  • Detect clogged fans or air ducts automatically.

Features of P5 series matching Clean Room Fan application



Dual digital tube

Double lines of LED display, monitoring 2 kinds of information meantime, like frequency, current, voltage, speed and PID data.

Smart restart

Instant power off continue running and speed tracking

Independent cooling channel design

Independent cooling channel design. This is good for applications like printing, textile, cement and steel factories where severe environments exist.

Terminal control

Multiple control terminal, 6 DI, 4 DO, 2 AI, 4 AO, RS-485 support Modbus

A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
