Pulse Jet Filter Bag

During operation, dust-laden gas enters the baghouse and passes through the filter media from the outside to the inside. The dust is trapped on the outer surface of the bag, forming a “dust cake,” while clean air exits through the top. When the pressure drop reaches a certain level, a pulse of compressed air is shot down into the bag, causing it to expand rapidly and shake off the accumulated dust into a hopper below.

• High-Quality Filter Media: Typically made from needle felts like Polyester, PPS, or PTFE. We offer advanced surface treatments such as PTFE membrane to enhance filtration and dust release.
• Sturdy Bag Head Design: Featuring various top configurations including snap rings, cords, or cut edges. These designs ensure a precise fit and a leak-proof seal with the tube sheet, sometimes incorporating grounding wires for static dissipation.
• Reinforced Seam Construction: Our Pulse Jet Filter Bag features high-quality seams (sewn or welded) designed for the lowest emissions. Additional PTFE seam sealing is available for ultra-fine dust applications.
• Robust Floor/Bottom Construction: To extend service life, the bottom is double-layered or features reinforced floor covering to withstand mechanical stress and high-velocity abrasion.
• Support Structure (Filter Cage): A metal skeleton that provides internal stability. For specific applications, stiffening rings can be integrated for improved structural integrity.

In industrial filtration, the geometry of a Pulse Jet Filter Bag is a critical factor that determines the filtration area, cleaning efficiency, and space utilization of the baghouse. Depending on the equipment design and operational requirements, these bags are manufactured in several distinct shapes.
