What color is the medium efficiency bag air filter?

The medium-efficiency bag air filter can be used for the intermediate-level filtration of the air-conditioning system to protect the next-level filter in the system and the system itself. In places where the requirements for air purification and cleanliness are not strict, the air treated by the medium-efficiency filter can be delivered directly to the user. The aluminum frame bag filter adopts high-quality synthetic fiber or imported glass fiber as the filter material, the outer frame of aluminum alloy profile, and the inner sprayed cold-drawn wire support frame.

What are the characteristics: the medium-efficiency bag air filter has large effective filtering area, large dust holding capacity, small resistance and large ventilation; the frame and support frame can be reused, and only the filter bag needs to be replaced when replacing the filter, which is convenient and fast, greatly reducing operating costs. It is widely used in filtration systems in electronics, pharmaceutical, medical, food and other industries, and is currently the best-structured medium-efficiency filter.

There are five common efficiency grades for medium-efficiency bag air filters:

F5 medium-efficiency bag air filter, the color is white, and the efficiency is 40%~60%. The number of commonly used bags is 6, 5, and 3. Pre-filter for medium efficiency filtration

F6 medium-efficiency bag air filter, the color is green, the efficiency is 60%~80%, the number of commonly used bags is 6, 5, and 3.

F7 medium-efficiency bag air filter, the color is pink, the efficiency is 80%~90%, the number of commonly used bags is 6, 5, and 3.

F8 medium-efficiency bag air filter, the color is light yellow, the efficiency is 90%~95%, the number of commonly used bags is 6, 5, and 3.

F9 medium-efficiency bag type air filter, the color is dark yellow, the efficiency is more than 95%.
