DRY AIR
1.0
Air entering a bag house type dust collector must be dry and oil free.
DUST BAGS
2.0
Dust bags are made from a dacron or shaker felt filter material.
2.1
Dirty Dust Bags:
As air containing particles is drawn through the dust bag, the particles are trapped
on the outside of the bag.
2.1.1
A certain amount of particulate matter will always remain on the outside of the bag,
even after shaking. This is normal and greatly improves the efficiency of the bag as
a filter. This is called a "seasoned" filter bag.
2.2
As particles build-up on the dust bags, the resistance to air flow will increase. When
this resistance reaches a point that flow has been restricted, it hampers the
operation of the system. The bags should then be shaken to remove the particle
build-up.
2.3
Shaking Dust Bags:
With a manual system, move the bag rapper handle 10-12 times in such a manner
that the rapper paddle strikes the bottom of the bags after eight (8) hours of
operation.
2.3.1
Powered Bag Rapper:
Rap 10-15 seconds after eight (8) hours of operation or as needed.
