Filter Element Manufacturing and Assembly Services

All filter manufacturing and assembly services are done in-house, from the production of your filter to the building of the dedicated equipment used in production. We discuss with you the various methods to achieve economically, cost-effective production concepts fitting into your envelope size and flow requirements. We assist you in the selection of the appropriate filter construction materials.

Examples: The attaching of filter end caps; Seaming of the pleats (hot melt, plastisol, epoxy, spot welding); Selection of the right o-rings, seals, and gaskets. We then design and build the dedicated filter manufacturing machinery (i.e. pleaters, seamers, dispensers, etc.) to meet your projected usage.
