The standard size and efficiency issues for medium-efficiency air filters

Medium-performance air filter standard size complete, can be used for air conditioning system of intermediate filtration, to protect the next level of the system filter and the system itself, in the air purification cleanliness requirements are not strict places, the air treated by the medium-performance filter can be sent directly to the user, aluminum frame bag filter using high-quality synthetic fiber or imported glass fiber as filter material, aluminum alloy profile outer frame, internal plastic spraying cold-drawn wire support frame.

The standard size of the medium efficiency air filter is complete, with a large effective filtering area, large dust holding capacity, low resistance, and large ventilation capacity;
the frame and support frame can be reused, and only the filter bag needs to be replaced when replacing the filter, and it is convenient and quick, which greatly reduces the operating cost and expense, and it is widely used in the filtration system of the electronic, pharmaceutical, medical and food industries, and is the best structured medium efficiency filter.

Efficiency: F5 (45%), F6 (65%), F7 (85%), F8 (95%), F9 (98%)

Frame thickness series: 21mm, 25mm, etc.;
(F5, 45%, white, used for medium filtration before the filter)
(F6, 65%, orange, used for commercial buildings, theatres, stations, airline stations)
(F7, 85%, green, used for spray paint rooms, schools, computer rooms)
(F8, 95%, pink, used for industry, pharmaceuticals, food, hospitals)
(F9, 98%, yellow, used for precision electronics industry, defense factories, sterile rooms)
