Foldaway paper frame filter mesh Speciality:
The filtration material is made fromnon-woven fabrics, and the synthetic fibre .it has the advantage of  the large dust holding capacity, the low pressure loss in the initial period and lager air flow.
The filtration material compounds with the material net, and is designed into the foldaway, which will provide the current air with the largest filtration area, 5 times’ filtration area as the common plane mesh. Paper frame and metal frame are available, which is convenient for replace; Less purchasing expense
 The moisture-proof  100%;
Heat resistance 80℃;
The rank of the filtration: G4.F5.F6.F7.F8.
 Using:
Pre-filter for the air-condition filtration system. It can lengthen the working life of the middle and high efficiency filter.
