P84 Filter Bag

P84 filter bag has excellent performance of heat-resistance and great filter efficiency.It can be used in the cement plant.
Our capacity: 20000 per month (standard product)
Diameter & Length: Accept customization
Filtration precision: ≤30mg/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.

Features of P84 Filter Bag:

  1. Max. Operating temperature: 240℃/464℉; Ultimate temperature: 260℃/500℉
  2.  Due to it’s leaf-shaped cross section, It’s 80% increase in filtration area than other filter Media.
  3. The properties of Hydrolytic and Oxidation resistance are moderate. We suggest the water vapour content less than 35%Vol and O2 content less than 16%Vol.
  4. Oxysulfide will shorter the service life of P84 bag, the suggestion content of oxysulfide should be less than 700mg/Nm3; the waste incinerator should have the desulfurizing unit.
