Cost-Effective, Reliable Polyester Baghouse Bags for General Industry
Skytech Ultrafab Polyester Dust Collection Bags are the most widely deployed filter bags for general industrial dust collection at ambient to 135°C. Manufactured from quality needle-punched polyester felt, they deliver reliable ≥99.5% filtration efficiency on dusts from grain handling, wood processing, plastics, pharmaceuticals, food, and general manufacturing at an economical cost per tonne of product.
What Are Polyester Dust Collection Bags?
Polyester (PES) Dust Collection Bags are the standard choice where process temperatures do not exceed 135°C and where corrosive chemical conditions are absent. Polyester fibre offers an excellent combination of mechanical strength, heat resistance, and hydrolysis resistance at a cost that is significantly lower than specialty fibres like Nomex or PTFE.
Features and Benefits
- Up to 135°C Service: Stable mechanical performance at continuous operating temperatures up to 135°C — suitable for the large majority of industrial dust collection applications
- High Mechanical Strength: Polyester felt resists the repeated mechanical stress of pulse cleaning for over 100,000 pulse cycles in standard duty applications
- Smooth Cake Release: Singed and calendered surface treatment creates a smooth, closed surface that promotes clean cake drop with each cleaning pulse
- Hydrolysis Resistance: Good resistance to steam condensation at moderate temperatures — superior to nylon in humid process conditions
- PTFE Membrane Option: Surface lamination with ePTFE membrane significantly improves emission performance and further reduces cleaning pulse frequency
- Full Range of Sizes: Diameters from 100 to 300 mm and lengths from 2 to 10 m covering all standard pulse-jet, shaker, and reverse-air baghouse designs
