Selection of Bag Filter Bag for Bag Dust Collector: Matching Guide by Dust Type
There are significant differences in particle size, humidity, corrosiveness, temperature, and other dimensions among different types of dust. Blindly selecting universal filter bags can easily lead to filtration failure, premature damage to filter bags, or a sharp increase in maintenance costs.
Key words:
For overseas factories, the "soul" of bag filters is not the equipment casing, but the filter material - if the filter material is not selected correctly, it is prone to softening and damage under high temperature conditions, and will quickly age in corrosive environments.

Bag filter: PPS filter bag is heat-resistant and environmentally friendly for chemical dust removal
The dust removal problem in chemical workshops always revolves around "high-temperature flue gas" and "corrosive dust" - the flue gas discharged from reaction vessels and distillation towers often reaches 200-260 ℃ and is mixed with corrosive gases such as SO ₂ and HCl. Ordinary filter bags soften and break after 3-6 months, causing frequent shutdowns and bag replacements, as well as being fined for excessive dust leakage.
Key words:
For factories operating under high temperature and high corrosion conditions overseas, filter bags, as the "core consumables" of dust removal equipment, often face the problem of "high-temperature softening, corrosion and damage" - ordinary polyester filter bags are prone to deformation above 150 ℃ and need to be replaced after 3-6 months, which not only wastes money but also frequently shuts down and affects production.
Key words:
The flue gas temperature under high temperature conditions often reaches 200-260 ℃, and ordinary filter bags are prone to softening and damage, leading to dust collector shutdown and excessive emissions.
