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
