Apart from the control panel, the front panel of the machine is also fitted with some devices to control the
pressure, the discharge of the condensate, the strainer filter and the level of the lubricating oil
(Fig. 45-46). Bear in mind that for model MCH 26-32/ET Compact, all the devices are double.
1 Pressure gauge
It indicates the working pressure.
2 Pressure switch
It enables the maximum cylinder filling
pressure to be set and displayed.
During the cylinder filling phase, the pressure
switch stops the compressor when it reaches
the maximum pressure as shown by the red
cursor.
3 Strainer filter
The purpose of this device is to withhold the
impurities present in the air before they enter
the cylinders.
4 Condensate discharge taps
They enable the condensate that has
accumulated during machine operation to be
discharged by hand.
The condensate is discharged automatically
by the machine by means of electroma-
gnetically-controlled valves.
