9.6 Replacing the active carbon
When replacing the active carbon, make sure to wear your personal protective equipment,
namely the respiratory protection and goggles.
Risk of slipping if material is spilt!
The service life of the active carbon does not need to be determined with accuracy as there
are many factors which can reduce or increase the service life. In favourable conditions, the
service life can exceed 10,000 hours. Proceed as follows to replace the active carbon:
1. Depressurise the adsorber.
2. First, open the sealing plug on the top (1).
3. Place a collecting vessel underneath the bottom sealing
plug (2) and remove it.
4. Collect the active carbon as it runs out.
5. Empty the vessel completely.
6. Blow through the sieves inside the vessel.
7. Close up the bottom sealing plug again and pour the active carbon
material through the top opening.
8. Fill in the activated carbon material to the lower edge of the upper
diffuser. At higher filling may lead to increased dust content in the
afterfilter.
9. Screw the top sealing plug back in again.
We recommend that you only change the filter element after the active carbon has been chan-
ged. To do so, allow the adsorber to run for half an hour. The dust particles that accumulate
are hereby captured in the after-filter element which is to be replaced. Only then replace the
filter element.
It can happen that the compressed air which has already been dried by an adsorption dryer,
becomes moist again (rising pressure dewpoint). This is due to the moisture stored in the ac-
tive carbon which is rinsed again after a few days.
Contaminated active carbon material must be disposed of in accordance with the local regula-
tions! As a rule, the disposal code is:
„Used active carbon“ with the disposal code number: 06 13 02
If other toxic or hazardous substances have been stored, then this must be determined by
the operator and the active carbon must be disposed of taking the type of contamination into
consideration!
