Plastic Mesh Components for Filter Element Manufacturers
Netting, mesh and rigid mesh tubes are used in filter cartridges for automotive, HVAC, water purification, hydraulic filtration, fuel filtration, beverage filtration, medical filtration, and food processing applications.
- center core supports
- flow channel spacers
- outer wraps & media containment
- protective filter sleeves

Rigid Mesh Tubes
Extruded cores provide structural support in cartridge filtration. Designers can chose from a wide range of diameters, apertures, and open areas. And unlike injection molded cores, custom designs typically have minimal tooling costs.
We also custom fabricate tubes to larger diameters from a variety of flat mesh or nonwoven products or bond nonwovens to the outer surface of rigid tubes using our welding capabilities. This short YouTube video illustrates alternatives available in both rigid mesh tubes and custom formed tubes.
Flow Channel Spacers
Create a flow channel across the filter medium. Many spiral wound filter elements use bi-planar diamond netting as a "feed spacer" allowing the liquid stream to flow across the membrane surface. More recently, rectangular mesh feed spacers have been developed as an alternative to diamond mesh netting. They are engineered to create uniform multiple thin strands in one direction and more widely spaced, thicker strands in the perpendicular direction. Woven Mesh is available in polypropylene, nylon, and polyester.
- Diamond Mesh: bi-planar spacers to 1/2 mm thick
- Square Mesh: mono-planar support to 1/3 mm
- Woven Mesh: uniform openings to 1 micron
Flexible tubular sleeves can be stretched over the filter element to protect the outside surface of the filter medium from damage during use and handling. Or square mesh can be wrapped and bonded around the outer surface of the filter media. For even more rugged surface protection, rigid tubes can be used as outer sleeves to protect the filter element.
Netting can help retain a given shape or provide support to filter media and membrane-based material against the liquid or air stream. Plastic netting is more rigid than a woven or nonwoven materials and can support material in pleated cartridge filters with relatively uniform separation between the pleats while providing enough rigidity to keep all of the pleats uniformly exposed to the stream, helping to improve the filters' efficiency.
