H3:What is the Liquid Filter Bag?

Liquid filter bags are filter elements used in bag filter housings to separate solid particles from liquids. Filter bags are made from various synthetic fabrics, including needle felt, mesh, and melt-blown materials, to meet different filtration precision requirements and applications across various industries.

How does the Filter Bag Work?

The fluid to be filtered enters through the top collar of the filter bag. As it passes through, particles are caught by the filter cloth while the clean fluid exits from the outside. Over time, trapped particles build up, increasing the pressure difference across the bag. This indicates that the filter bag needs to be replaced.

What does a Filter Bag Consist?

  • Seal ring (bag collar)
  • Handle
  • Bag body (fabric)
  • Seam: sewn or welded
  • Bag bottom

Specification

Material Options

Needle Felt

Needle felt is a durable, nonwoven fabric created by needle-punching fibers together, with deep filtration ranging from 0.5 to 200 μm.

  • Polypropylene
  • Polyester
  • Meta-Aramid
  • PTFE

Melt Blown

Melt blown fabric, a fine nonwoven made from extruded polymer microfibers, excels in fine filtration and oil absorption, filtering 0.15 to 125 μm.

  • Polypropylene
  • Polyester

Mesh

Mesh fabric is a net-like structure offering flexibility and strength, with surface filtration ranging from 1 to 1500 μm.

  • Nylon
  • Polypropylene
  • Polyester
  • PEEK

Types of Seal Rings

The seal ring is also known as the filter bag collar

G Ring

Seadon's G ring matches Eaton's SENTINEL style, available in polypropylene, polyester, and nylon for diverse needs.

F Ring

Seadon's F ring mirrors FSI's PolyLoc style, available in polypropylene and polyester for versatile applications.

X01 Ring

The X01 ring matches FSI's PolyLoc style, designed for X01 (size 5) filter bags, available in polypropylene and polyester.

Snap Ring

The snap ring features a circular design, made from galvanized iron, stainless steel, or PTFE for durability.

Types of Bag Seam

Welded Seam

Welded seams use ultrasonic welding to heat and bond felt fabrics, creating a strong and leak-proof seal

Sewn Seam

Sewn seams stitch bag fabric with thread, offering high strength and cost-effectiveness, commonly used in steel ring and mesh bags

Types of Bag Bottom

Arc-shape

An arc-shaped bag bottom has a rounded design that spreads stress evenly, lowering tear risks and enhancing durability

Triangle-shape

A triangle-shaped bag bottom directs flow inward, increasing center pressure and potential breakage, so it's less recommended

Overlock Stitch

This bottom uses overlock stitching to secure edges, preventing fraying and adding strength, making it cost-effective and durable for steel ring and mesh bags

Invisible Stitch

This bottom uses invisible stitching on the outer cover layer of multi-layer filter bags to enhance appearance.
