Built for High-Intensity Pulse-Jet Cleaning in Industrial Baghouses

Skytech Ultrafab Pulse-Jet and Reverse Pulse-Jet Dust Collection Bags are engineered to withstand the repeated mechanical shock of high-pressure compressed-air pulse cleaning in online and offline baghouse systems. Manufactured from premium needle-punched polyester, polypropylene, acrylic, fibreglass, or Nomex felt with optional PTFE membrane lamination, these bags maintain structural integrity through thousands of pulse cycles while delivering 99.9%+ filtration efficiency on fine dusts.

What Are Pulse-Jet Dust Collection Bags?

Pulse-jet baghouses are the most widely used industrial dust collection technology. Filter bags hang vertically from a tube-sheet, and a venturi-assisted blast of high-pressure compressed air is periodically directed down the inside of each bag, momentarily inflating it and dislodging the accumulated dust cake. The bags must withstand this repeated rapid inflation-deflation without seam failure, media fatigue, or loss of filtration efficiency — while maintaining continuous filtration on all non-cleaning compartments.

Features and Benefits

• Pulse-Resistant Seam Construction: Double lock-stitch seams with chemically resistant thread prevent seam fatigue failure under thousands of repeated pulse-jet inflation cycles
• ePTFE Membrane Option: Surface filtration membrane prevents dust from penetrating the media depth — enabling complete cake release with each cleaning pulse and consistently low differential pressure throughout filter life
• Wide Fibre Range: Polyester, polypropylene, acrylic, Nomex, P84, PTFE, and fibreglass needle-felt options — the correct fibre matched to each combination of temperature and chemical environment
• Antistatic Options: Carbon fibre or stainless steel antistatic blends available for dust collection in explosive or electrostatically sensitive dust environments
• Snap Ring and Collar Top Styles: Snap ring, collar top, plain top, and clamp-band configurations for direct fitment in all standard pulse-jet baghouse tube-sheet designs
• Custom Diameter and Length: Bags manufactured from 100 mm to 300 mm diameter and 2 m to 10 m length to fit all OEM and custom-built pulse-jet baghouse designs

Technical Specifications

Applications

• Cement Industry: Raw mill, kiln, clinker cooler, and cement silo pulse-jet baghouses — the largest single application for industrial dust collection bags
• Steel and Foundry: EAF fume collection, blast furnace casthouse, and foundry shakeout dust collection in high-temperature pulse-jet systems
• Chemical and Pharmaceutical: Reactor vent, dryer exhaust, and powder handling dust collection where chemical resistance and emission compliance are both required
• Food and Grain: Grain elevator, flour mill, and food processing pulse-jet dust collectors — food-grade PP or antistatic PES bags for explosive dust environments
• Power Generation: Coal handling, silo vent, and fly ash conveying dust collection with pulse-jet baghouses across coal-fired power plant auxiliary systems
