vaccuumProduct1Recoverable Sewn or Rubber End Filter Elements.

Classic radial fin textile media elements are unsurpassed for low ΔP, dirt holding capacity and efficiency. They stop particulates before they can move downstream. Select either recoverable 10µ Sewn End Filter Elements or 10µ long life low cost polyurethane rubber molded end elements, as your needs dictate to remove 98% of all airborne dust and dirt. Unlike PVC or Plastisols, these polyurethane rubber ends have no phthalate elastomers to evaporate away in vacuum service. Our synthetic rubber is cross linked to further limit outgassing*. Dozens of alternative filter media are available for services having finer micron retentions, elevated temperatures and/or aggressive chemistry.

*If trace molecular contamination is of concern in your vacuum service, contact us for specifics.


Models P20-0087-RF-040 and larger include CS leg supports (add 18" to OH). Carbon steel support legs in any length, gauges and special finishes. Call for information on vessels having other pressure services, 304SS, or other materials of construction.
