Mesh Cores & Cages for Filter Elements

Extruded plastic netting in rigid tube form provides structural support as center cores in filter cartridges.   Rigid mesh cages are also used as outer containment sleeves to protect filter media from damage during handling and cleaning.

 The ready availability of a wide range of configurations – and the minimal tooling costs associated with custom designs – make extruded cores a favorite for filter design engineers. 

Measurements & Tolerances

Dimensions of Rigid Mesh Cores & Cages

Rigid mesh tubes are extruded stock in common lengths.  This as extruded, or "rough cut" tolerance for length and square is +/-0.25".

To create custom lengths with more precise dimensions stock extruded tubes are cut on rotating spindles. Nominal "finished cut" tolerance is +/-0.030" for lengths less than 46 inches or +/-0.060" for lengths from 46 to 94 inches.

Tube diameters can vary slightly from lot-to-lot due to shrinkage variability. Inside Diameter (ID) and Outside Diameter (OD) tolerances are typically +/-0.020" for most configurations.

Custom Sizes

Chose from a wide range of diameters, apertures, and open areas to get the flow characteristics and structural support required for your application.  Don’t see what you need below? 

We also custom fabricate tubes from a variety of flat mesh or nonwoven products.
