Product Details:
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.

Tips:
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.
