Round Polyester Dust Filter Bag Bag House PE Conventional Bag PE
Felt Filter Bag Dust Collector PE Bag
1. Specification
Polyester is a resin formed by the esterification reaction of
dicarboxylic acids with diols. Polyester is used in low temperature
filtration and can be degraded in application where moisture is
present. We choose cascaded blend of different fiber sizes with the
finer fiber concentration in the filtration surface to make the
product not only have the common felt’s advantage of high voidage,
good air permeability, high dust collection efficiency, long
service life, etc , but also have the advantage of the moderate
temperature rating, can reach 150℃ at the moment, moderate effect of the anti-antacid and
anti-alkali, and has very good abrasion resistance.
Finish Treatment: Singeing, Calendering, Heat Setting, Anti-static, Water&Oil Repellent, PTFE Membrane, PTFE Impregnation and so on
Bag Size: it is up to the CPO and installation and customized
Bag Head: seal cuff / groove snap / felt strip, bead cuff/ steel strip, etc
can be chosen
Bag Body: Sewing or Hot sealing
Bag Bottom: Single or double bottom, with reinforcement or without
reinforcement
