Glass fiber mats are made of extremely fine, regular glass fibers, whose density in-creases from the air-intake to the clean air side. As a result of this progressive constructions which is the most important characteristic for a high performance fiberglass filter.Technology :These are of premium quality manufactured by melting the glass by electrical energy.Advantages : Low Initial resistanceHigh separation efficiencyDifferent color on inlet and outlet sideFlexibleEconomical and practicalLong service lifeRegularity of pressure drop-increasehigh holding capacity of dust and paintApplication :Type : Supply slices or rolls sizeMedia : Fiber glass with gradual density, inlet side is green, yellow color, outlet side is white. EN779 class : G3, G4 Average arrestance : 93% (ASHRAE52.1-1992) EUROVENT4/5 class : EU3, EU4 Average separation efficiency : 95 % Final resistance : (suggest) 130Pa-200Pa Temp resistance : 170
