Sealed Filter Elements (CGR)

Abgedichtete Filterelemente

LENSER filter elements are also available in sealed form. These are based on standard chamber filter elements (KF). For differentiation from the classic LENSER KF, they are assigned the suffix CGR (caulked-grooved) in the nomenclature.

CGR plates are used when the filter chambers must be drip-proof. LENSER offers a variety of sealing materials such as EPDM, silicone, NBR and FKM, depending on the resistance requirements.

For the food and pharmaceutical sector, we use FDA or EU-compliant seals, among others.


  • For filter chambers that must be absolutely tight
  • Equipped with cloth tension groove (Omega or U-type) and O-ring sealing
  • Various sealing materials available depending on requirements
  • FDA-compliant, antistatic or ATEX-compliant on request
  • Compatible with critical chemical conditions through the use of additives
  • Also available in PVDF for chemically harsh conditions


Do you need filter elements for use in an explosion-proof application according to ATEX RL/94/9/EG?

LENSER is a certified manufacturer of electrostatically dissipative filter elements of device category 2G for use in explosion protection zone 1.

We confirm the conformity of the filter elements with the ATEX directive by issuing a corresponding certificate.
