| Message: | Pre air filter used in before the filtering progress, it can filter the big size dust first.So we use the thicker fiber to make the polyester felt and sewn or welded into the pre filter, theSpecification as following:Media: Polyester fiberRecommended final pressure drop: 450PaTemperature: 100ºC maximum in continuous serviceFlammability: F1 self extinguishing（DIN53438）Advantage:Built up by high-quality original polyester fiberProgressively built up thermal bonded fiber, from the upstream to the downstream, changed from sparse to compact. So as to get full deep particle collection and low pressure dropTreated with special adhesive at 3D processing, ensures that each fiber covered with glue, prevent dust loss due to vibration 3D Downstream support with "＃" mesh, which can effectively prevent fiber off Compact of stable fiber structure, enhances laminar air flow (within ±5%)Application: As fine pre air filter for customized ventilation system or equipment Particularly suitable for final filtration of spray booth, paint shop(Rolls) capacityModelDimensions (rolls)ThicknessFilter calassificationpressure drop(pa)dust holding capacity(g/m2)W*L(M)T(mm)EN779:2012@0.25m/s@0.5m/sSff600G2.0*2020M52555480Sff650G2.0*2020M63580550 url:http://www.sffiltech.net |
