ACTIVE CARBON FILTER / MOLECULAR SIEVE
7.11
The active carbon filter must be replaced at intervals calculated on the basis of the characteristics of the
environment in which the compressor is located. To calculate these intervals refer to the table below.
The filter must nevertheless be replaced before the air becomes malodorous.
IMPORTANT
If the compressor is used in an environment where CO (exhaust fumes) may be
present it is compulsory to use CO-fixing filters; these can be supplied on request.
IMPORTANT
For compressors used in the USA and CANADA the use of LAWRENCE FACTOR
filtration cartridges is recommended.
DANGER
Do not carry out these tasks if the compressor has only just shut down; wait for the
compressor to cool.
All maintenance work must be carried out with the compressor OFF and the power
supply lead unplugged from the mains socket.
Depressurise the entire compressor circuit before carrying out any maintenance
tasks.

) proceed as
follows:
- vent all the compressed air inside the circuit.
- use the tool (
