Hi,welcome to CLEAN-LINK!

Medium efficiency bag air filter F5 | F6 | F7 | F8 | F9 what's the difference?


Medium-effect bag air filter is widely used in production and life, which is distributed with its structural characteristics. The windward side of the bag filter is large, so it has large dust capacity and low wind speed, so it is considered to be a good medium-efficiency filter structure at present.

The medium-effect bag air filter protects the lower filter in the system and the system itself. in places where the cleanliness of air purification is not strict, the air treated by the medium-effect bag air filter can be sent directly to the user. Aluminum frame bag filter uses high-quality synthetic fiber or imported glass fiber as filter material, aluminum alloy profile outer frame, internal spray cold-drawn wire support frame.

Medium efficiency bag air filter

Performance parameters of medium efficiency bag air filter. 
Outer frame: galvanized steel outer frame, 20mm thick flange. 
(2) filter media: melt blown ultra-fine glass fiber filter material, v-shaped filter bag structure. 
(3) filtering efficiency: 
1) F5 (EN779), 40-60% ASHRAE 52 Universe 76. 
2) F6 (EN779), 60-80% ASHRAE 52 max 76. 
3) F7 (EN779), 80-90% ASHRAE 52 max 76. 
4) F8gam9 (EN779), 90-95% ASHRAE 52UA 76. 
(4) Fire rating: UL-2 (UL 900). 
(5) temperature tolerance: ≤ 90 ℃. 
(6) moisture resistance: ≤ 95% RH. 
(7) it is suggested that the final resistance is ≤ 350 Pa (F7 and F8, 9) and ≤ 250 Pa (F5, F6). 
Medium efficiency bag air filter F5 | F6 | F7 | F8 | F9Z what's the difference? 
In fact, the biggest difference in F5 | F6 | F7 | F8 | F9 bag filter lies in its filtering efficiency, in fact, it is the distinction of color. F5 is orange, F6 is green, F7 is pink, F8 is yellow, this color is not absolute, different manufacturers have their own colors, the main role of the color here is to separate different efficiency filters. 
To sum up, the medium-effect bag air filtration apparatus has the advantages of large effective filtration area, large dust capacity, low resistance and large ventilation; the frame and support frame can be reused, and the filter bag only needs to be replaced when the filter is replaced, and the operating cost is greatly reduced. And in terms of application, it also has a wide range of applications, such as: electronics, pharmaceutical, medical, food and other industries filtration system, is the best structure of the medium-efficiency filter.
