Filters and cages
Bag filters are composed of a microperforated fabric, made in the form of cylindrical sleeves, attached to the filter body and supported with the help of metal cages. Filter bags must fit tightly to the cage to prevent wear on the bags themselves, but they must also be flexible enough to be removed for cleaning. The proper fit between bag and cages is an important feature to ensure proper adhesion and long durability.
Without the support of filter cages, the dust removal filter bag cannot complete the air purification process.
