The efficiency filters in the air filter in an F series filter. F series in the sub-efficiency air filter bag and non-bag two, which includes non-bag bag bag FB (plate in effect filter), (diaphragms in efficiency filter (combined filter in effect). 
 For the filtration efficiency (colorimetric) 
 The efficiency filters in the industrial application 
 Mainly used for central air conditioning and ventilation systems intermediate filter, pharmaceuticals, hospitals, electronics, food, and other industrial purification; 
 High efficiency filter can be used as front-end filter to reduce the high over load and prolong its life; 
 As the windward side of the large, so large amount of space dust, low wind speed, is considered the best in efficiency filter structure. 
 Characteristics of the filter in effect 
 1 1-5un capture dust particles and various suspensions. 
 2 air volume. 
 3. Resistance. 
 4 high dust holding capacity. 
 5 reusable cleaning use. 
 6 Type: Frameless and Frame Bag 
 7. Filter: Special non-woven glass fiber or 
 8 Efficiency: 60% ~ 95% @ 1 ~ 5um (colorimetric) 
 9 the highest temperature, humidity: 80 ℃, 80%
