7.11 - ACTIVE CARBON FILTERS / MOLECULAR SIEVE
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.

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 wrench (

If the compressor is used in an environment where CO (exhaust fumes) may be present it is
compulsory to use CO-fixing filters (CARULITE® 300); these can be supplied on request.
