K filter Three stage intake negative pressure filter under the condition of the power units intake negative pressure KIN/GX type filter intakes ambient air, when the air with dust goes through the first, second and third stage (fourth stage if required) filter elements, the big size particles in the air will be filter by the first and second stage filter elements for the sake of the gravity and inertia force. The small size and low density of the dust will be filtered on the third and fourth stage surface of the filter media by the Brownian diffusion, fiber intercept and other combined effect. The filtered air flow into the clean room and past the outlet duct to power unites.
First stage is rain cover with liquid – solid separator
Second stage is F6-F9 filter cartridge
Third stage HEPA filter H10 – H12
Horizontal air flow
Second stage filter cartridge with Pulse dust cleaning.
