Pleated Bags versus Bag Filters

THE ADVANTAGES OF PLEATED BAGS

Increased durability, better efficiency, energy savings, reduced emission levels and easier installation

BAG FILTER

Approx 6 m. long

 

PLEATED BAGS

Max. 2 m. long

Benefits of Pleated Bags

  • Polyester media and PU end caps in the bottom prevent abrasion/leaks
  • Can be retrofitted into existing bag filter dust collectors using existing tube sheet holes (adaptor rings enable easy installation in tubesheets ranging
    from 152 - 167 mm diameter)
  • Short pleated bag filters can optimize the capacity of existing collectors - hence prevent the need to invest in larger baghouses. Also, they require less air for efficient pulse cleaning

Bag Filters vs. Pleated Bags

Surface

Pleated bag cartridges are surface filtration cartridges.

BENEFITS OF SURFACE FILTRATION:

> Less accumulation of dust
> Less pressure drop
> Longer filter life cycle
