Filter Control - New Standard

Application Description | Traditional Solution | Energy Savings
Click here to read more about:  PID Control, VVC plus

Using a drive in co-operation with a pressure sensor, the supply fan can maintain a precise flow rate. Since the CAV system does not modulate, the pressure downstream of the filter is proportional to flow. As the filter becomes dirty and its pressure drop increases, the drive automatically increases the speed of the fan to compensate. In addition to allowing true constant air volume control, the drive saves energy and provides a soft-start increasing the life expectancy of the filters.
