10.1.1Compressed Air Inlet Filters

1
This procedure is for replacing the filter element for the two compressed air inlet and located on the
left-hand side of the box (Fig 1). Make sure the correct filter element is installed in the correct filter.
1.0 Important: The air inlet valve (located immediately upstream of the filters) must be fully closed
and the air pressures (as read on the pressure gauge that is immediately downstream of the
filters) must be fully depressurized and read 0 psi. Serious injury may result if the filter bowl is
removed when there is pressure in the bowl.
2.0 With no pressure in the system, unscrew the four screws in each corner of each filter housing
cap (Fig 2) with a 4mm Allan wrench. A ball ended wrench typically works best. 5/32 will also
work. Remove 8 screws total.
3.0 Remove the existing filter elements.
4.0 Insert the new filter elements into each filter bowl and carefully refit into the filter housing cap.
Note that the filter element can only fit in one position and must be installed correctly, so the air
inlet aligns properly. The new filter element number must match that listed for the filter housing.
Make sure the correct filter element is installed, as each filter requires a different filter element
and they look the same.
5.0 Replace the 4 mm screws and tighten. Restore operation.
Note that the filter elements in each filter are different (although they look the same) and they must
be installed in the proper filter! The first filter has a coarser element that removes most of the
liquids and the second filter has a finer micron rating that removes the last traces of liquids and
particles. When replacing the filter elements,
