High-pressure filter for compressed air
Operation
Avoid abrupt pressure rises or drops during
filter operation. The filter can be damaged if the
pressure rises or drops too fast.
Maintenance
Always heed the prescribed service intervals.
Proper operation of the filter cannot be warran-
ted in case of non-compliance.
)
Also renew the O-rings of both housings
when changing each of the elements.
Daily
Drain the condensate accumulated at regular
intervals by opening the manual drain or using
a condensation drain. The condensate quantity
accumulating may have to be drained several
times a day.
Yearly
The filter elements V, XP, ZP must be changed
at a pressure difference of 0.6 - 0.7 bar or after
1 year at the latest.
If required
The activated carbon element A must be rene-
wed every quarter (at the latest after approx.
1,500 operating hours).
The following factors can require a premature
exchange:
high temperatures,
▌
high oil mist concentration,
▌
high relative humidity.
▌
This means you must perform regular measu-
rements to determine the optimum exchange
interval.

Replacing the filter element
- Block compressed air supply to the filter.
- Depressurise the filter. If necessary, open
the manual drain at the bottom of the filter
for this purpose.
Caution!
Depending on the size, the weight of
the bottom filter section may be 35 kg!
Secure the dead weight of the filter bot-
tom section using a suitable protective
device.
- Place the open-ended spanner on the
square of the filter bottom section and
unscrew the filter bottom section (Fig. 4).
- Unscrew the filter element clockwise
from the threaded rod (Fig. 3).
- Clean the filter mount and the thread of
the housing section.
- Renew the O-rings of both housings (Fig. 2).
- Lightly grease the thread area and the
O-rings with the recommended assembly
paste.
)
Recommended assembly paste:
Rivolta G.W.F.
- Screw the new filter element including
seal onto the threaded rod (Fig. 3).
- Screw the filter bottom section into the
top section by 2 to 3 thread turns. In
doing so, observe the ease of motion of
the thread.
- Screw the filter bottom section until you
can feel the resistance against the upper
O-ring.
)
A gap as thin as paper must remain bet-
ween the top and bottom section.
- Also close the manual drain and open the
supply line to the filter (Fig. 4).
- Check the filter for tightness.
- Dispose of the filter element only accor-
ding to the operating instructions.
