Industrial Baghouse Filter Bags for Every Dust Collection Challenge

Skytech Ultrafab Dust Collection Bags are the filtration backbone of baghouse dust collectors deployed across cement, steel, power generation, foundry, lime, carbon black, and chemical industries. Engineered from premium needle-punched felt in polyester, polypropylene, acrylic, fibreglass, Nomex, P84, and PTFE fibres, our bags are designed to the specific temperature, chemical, and mechanical demands of each application.

What Are Dust Collection Bags?

Dust Collection Bags (also called filter bags or baghouse bags) are cylindrical or envelope-shaped fabric elements installed in industrial baghouse dust collectors. Process gas containing suspended dust particles flows through the bag walls, which capture the dust on the outside surface while clean gas passes through the interior and exits to atmosphere. The accumulated dust cake is periodically dislodged by a cleaning mechanism (pulse jet, shaker, or reverse air) and falls into the hopper.

Features and Benefits

• High Filtration Efficiency: Achieves ≥99.9% collection efficiency on PM10 and sub-micron particulate matter across all industrial dust types
• Wide Temperature Range: PES bags handle up to 135°C; acrylic to 150°C; Nomex to 200°C; P84/PTFE to 260°C — material selected to application
• Chemical Resistance: Acrylic and PTFE fibres provide excellent resistance to SO₂, acid mist, and hydrolytic degradation in power plant flue gas
• Mechanical Strength: Needle-punched structure resists the repeated mechanical stress of pulse cleaning for thousands of cleaning cycles
• PTFE Membrane Option: ePTFE laminate surface significantly reduces pressure drop, improves dust cake release, and achieves sub-micron emission limits
• Full Cage & Hardware: Matching snap-rings, cages, and venturi nozzles available for complete baghouse filter assembly
