9.5.3. Understanding Gauge & Speed Control (MC)
Pressure Gauge
The MP 1200 gauge measures pressure in, Inch Water Column (Inch W.C.). The units are by
convention and due to the historical measurement of certain pressure differentials. It is used for
measuring small pressure differences across an orifice.
Normal operating pressure will vary per application. It is always best to make note of pressure gauge
reading after initial installation or after filter(s) have been replaced.
Typically when the gauge indicates higher pressures, one of the filters has become too dirty and will
need to be replaced or cleaned. Another indication of dirty filter will be machine tool cabinet not being
cleared of residual mist.
Speed Control
The speed control dial on the MP 1200 allows for greater control of the amount of suction provided by
the MP 1200 mist collector. When this dial is set, the MP 1200 will run at set speed while high
pressure is running, when high pressure is shut off the speed dial is by-passed and the blower speed
switches to maximum to clear the remaining mist in machine tool cabinet.
The MP 1200 speed may need to be adjusted per application.
Set blower speed to lowest speed setting that keeps machine tool under negative air
pressure. As the filters load it will be necessary to increase the blower speed to maintain
adequate airflow.
