The KLS-Pharma is the newest development for a contamination-free disposal of suction waste for the pharmaceutical and chemical industries (human contact with the suction waste has to be avoided at all times).
Therefore the cardboard cartridge with the integrated filter is disposed of together with the waste, whenever the whole unit is full. Different filter types are available, to enable a larger spectrum of applications.
For security reasons a secondary absolute filter is placed downstream. As is the case for the KLS-Standard, activated charcoal filters can optionally be installed to neutralize unpleasant gases or smells.
