K Filter ADSORB series oil absorption activated carbon fiber filter cartridge developed with extremely low-pressure drop thermal compression technology depth filter which composed of cellulose and activated carbon powder, It is combined with the dual function filter core material structure of activated carbon adsorption. The outer layer of the middle column of filter element is wrapped with precision fiber filter liner, supplemented with activated carbon fiber cloth, when fluids flows through the filter media, the outer layer of deep fiber filter can eliminate the pollution particles, the activated carbon cloth can eradicate the odor, precipitate,pigment, volatile organic compounds (VOC) and organic chemicals in the filtrate. Final the inner layer of media can prevent carbon particles and fine contaminants from escaping, provided with a final quality assurance and complete pure filtration.
