polyester punched felt filter bags factory

As one leading raw material of filter bags,polyester punched felt is achieved by lapping short polyester fibers onto staggered fine fibers with gaps equally distributed. Polyester punched felt has advantages of great intensity,sound elasticity recovery,stable woven sizes,relatively big gap, good air permeability,long lifespan,high efficiency dust filtering as well as  high acid-base resistance property and mechanical property under normal temperature circumstances. In addition,due to its low cost,this felt has been one economical filter media.

Dust keeps gather on surface of polyester punched felt bags with resistance increases on its two sides. Filtering efficiency decrease when big pressure differences of two sides,big enough to put afflicted fine dust inside.

There are varied installation ways for filter bags. One of frequent ways is spring tension ring opening, made of carbon steel slip and concave rubber sleeve.

Proper material filter bags should be selected based on factors like powder temperature,fineness,density,stickiness,moisture whether explosiveness or not etc.
