AIR FILTER ENGINE/COMPRESSOR
SERVICING
Always select the service point according to the vacuum
indicator or display message. A regular inspection or
cleaning as it is sometimes practiced in the field is more
likely to be damaging than useful as there is a risk that the
element will be damaged and dust will gain access to the
engine.
Atlas copco always recommends exchanging rather
than cleaning the filter element in order to avoid
damage and ensure maximum engine protection.
MAIN PARTS
CLEANING THE DUST TRAP
Remove dust daily.
To remove dust from the dust trap pinch the vacuator
valve (6) several times.
CLEANING INSTRUCTIONS FILTER
ELEMENT
If element cleaning can not be avoided, care should be
taken that the filter element (4) is not washed out. Please
note that engine damage can cause considerable costs,
which makes the cost of a new filter element seem
insignificant.
Safety cartridges (3) can not be cleaned but must be
exchanged.
Please note that a cleaned element will never match the
service life and performance of a new element.
Take the element from the air filter housing (5) (see
section Replacing the air filter element).
In order to clean, position a pipe with an end bent by
approx. 90° on the end of a compressed-air pistol. The
pipe must be long enough to reach the bottom of the filter
element. Carefully blow out the filter element with dry
compressed air (max. 5 bar (72.5 psi)) from the inside to
the outside until there is no more development of dust. The
end of the pipe must not touch the element.
Next carefully examine the element for possible damage.
Never beat or knock the element as this will damage it and
there will be a danger of damage to the engine.
Carefully clean the inside of the housing and put the
element in the housing (see section Replacing the air filter
element).
REPLACING THE AIR FILTER ELEMENT
New elements must also be inspected for tears or
punctures before installation.
Discard the element (4) when damaged.
A dirty safety cartridge (3) is an indication of a mal-
functioning air filter element. Replace the element and the
safety cartridge in this case.
The safety cartridge cannot be cleaned.
1. Release the snap clips (1) and remove the dust trap (2).
Clean the trap.
2. Remove the element (4) and the safety cartridge.
3. Reassemble in reverse order of dismantling. Make
sure the vacuator valve (6) points down.
4. Inspect and tighten all air intake connections.
The Atlas copco air filters are specially
designed for the application. The use of non-
genuine air filters may lead to severe
damage of engine and/or compressor
element.
Never run the compressor without air filter
element.
