Industry Polyester Dust Collector Filter Bag For Cement Mine Iron Pharmacy Bag House High Precision Filter Bag
Polyester (PE) filter bags
Polyester needle felt is made from polyester fabric by needle punch, and treat with singeing, calendering ,heat-setting process. This material has good friction resistance, high porosity, good twist resistance, good air permeability. It is a kind of wildly applied normal temperature needle felt .
We also provide FMS/ Fiber Glass/ PPS... filter bags, choose the material according to site situation.
Our capacity: 20,000 per month (standard product)
Size: Customization Accepted
Optional process: Sewing or hot welding
Filtration precision: ≤30mg/m³ (laminating PTFE film, ≤5mg/m³)
Finish-treatment: Calendering, Heat setting, Singeing
Optional Choice: Pleated Filter Bag (Star Bag)
The main advantages and features:
1. To increase system filtration capacity by 50-150% as needed without major changes to the dust collectors ;
2. System cleaning efficiency markedly increased with the effective increase of bag to bag distance;
3. Bag life extended due to significant reduction of fatigue damage to the bags due to bag to cage impact.

Precautions for dust bag installation
1. Old cloth bags of the new process should not be mixed, to avoid different damage time and affect the normal operation of the dust removal equipment.
2. Aging of cloth bags. Mainly due to the following reasons, a cause investigation is needed, corresponding measures are taken and the dust filter bag is replaced.
1).Due to abnormal high temperature and hardening shrinkage; 2). Due to contact with the acid, alkali or organic solvent vapor reaction; 3).React with moisture.
3. The filter cloth should not be hung too tightly or too tightly. It is easy to accumulate dust if it is too loose.
4.Replace the cloth bag, blow it with compressed air first, and then check if there are any holes. After the holes are repaired, leave them for replacement. As dust
Rinse the cloth bag, rinse it with water, and leave it for replacement after drying.
5.Blockage of dust bag. When the bag is clogged, the resistance increases, which can be expressed by the reading of the differential pressure gauge. Cloth Closure
plugs are the main cause of wear, perforation, and shedding of bags. The cause of the clogging of the dust bag is checked and repaired as follows.
1).Temporarily strengthen the dust removal to solve the clogging of the bag; 2).Replace the bag partially or completely; 3).Adjust the installation and operating conditions.
