7.6 Adsorption Cartridge Filter

(Optional equipment /USA standard)
The reason that the economy filter and the cartridge adsorption filter are both used on one machine is
that this provides separate filtration of pigment dirt and soluble dirt (fatty acids, dyes).
The insoluble pigment dirt is separated with the help of the extraction filter and the soluble dirt (especially
dyes) is adsorbed on the cartridge.
In case there is discoloration of the solvent during the cycle, it is possible to manually activate the
cartridge filter (7) in the filter circuit after the economy filter (6).
Steps for activating the cartridge filter:
- Open ball valves (2) and (3)
- Close ball valve (1)
If you want to remove the filter from the solvent circuit again and use only the economy
filter, make the following setting by hand:
- Open ball valve (1)
- Close ball valves (2) and (3)
