Frequency converter VFD-4
Fan equipment for fume extraction is often used without speed of flow control. Instead,
flow is traditionally controlled by throttling with a valve or damper or worse no control
at all. When flow is controlled without regulating the motor speed, the fan motor
continuously runs at full speed. Because welding fume control systems rarely require
maximum flow, a system operating without speed control wastes significant amounts of
energy over most of its operating life time.
Using a variable frequency drive (VFD) to control the motor speed can save up unexpected
amounts of energy and consequently also money, there is also the following advantages.
- Decrease in carbon footprint
- Less sound pressure
- Longer filter life
- Less compressed air consumed for filter cleaning
