ECOGRACE Metal Processing Polyester Filter Bags For Dust Collection

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.

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.
