Dust Collector System Polyester filter bags
GRACE Filter Polyester Needle Felt possess high porosity,good permeability
,high effective dust-collecting,long using-life etc. Common
character as ordinary filter felt . Besides, owing to its medial
temperature resistance (can teach to 150℃ in short time), medial
anti-acid and anti-alkali, especially its excellent anti-abrasion,
polyester needle punched filter felt have the largest quantity of
turnouts grams are from 350g/ to 800g/, thickness are from 1mm to
4mm, all above products can be manufactured in our company. The
surface treatment can be divided into singeing,calendering or
coated etc according to different working conditions.

Filter bags, dust collector bags, dust bags, filter socks, bags,
tubes, socks - they all mean the same thing: An industrial grade
fabric filter made from heavy duty material, all textile based,
used in dust collecting systems, in either process filtration or
pollution control.
Dust bags come in 5 basic designs:
Pulse jet bags (bottom loader or bottom removal)
Pulse jet bags(top loader or top removal)
Shaker design
Reverse air design
Envelope bags
Pulse jet bags are cleaned using compressed air to mechanically
"pulse" or snap the bag periodically so that the built up filter
cake is discharged and the flow through the media is returned to
its higher air permeability.Pulse jet bags are installed on wire
cage supports and filter from the outside/ in.
In the bottom load design, bags are pre-installed on their cages
and then attached to a mounting thimble or cup which hangs down
from the underside of the tube sheet. The tube sheet is a metal
plate with regularly spaced holes which serves as the top of the
gas tight metal box known as a dust collector. The top edge of the
bottom loading bag is normally tucked into the cage and the entire
assembly is attached to the thimble or cup with a hose clamp.
Installation of bottom loading bags is more difficult because of
being on the dirty side of the collector and having no catwalks or
surfaces on which to stand. Some bottom loaders are on the top of
large storage bins on tall silos which make installation
potentially dangerous.
