Polyester Dust Collector Filter Bag
Description of Polyester dust collector Filter bag:
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 .
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 Dust Filter Bag (Star Bag) and 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
