Activated carbon cartridges CAK and Hopcalite cartridges HCK KSI activated carbon cartridges of series CAK are highly effective oil vapour adsorption filters. They were specially designed to adsorb oil vapours and odours in compressed air and gas streams. Designed as a filter cartridge, each element is filled with granulated activated carbon. Large-pore metal sieves in the generous apertures ensure a low pressure difference at the inlet and outlet. High-grade filter mats trap contamination at the inlet and separate out any abrasion at the outlet. Advantages of CAK cartridges: - Longer service life than conventional elements - Better process control - Lower residual oil content - Higher dimensional accuracy - Cost-efficient solution in comparison to oil-vapour adsorbers - Can be retrofitted in all filter housings at any time
