Despite their robust construction, POROSTAR® wire mesh laminates are not immune to wear and damage. Thanks to the ability to choose between a complete replacement of the wire mesh laminate while reusing the flange ring or a targeted repair, companies can efficiently maintain their equipment and significantly extend its service life.

This not only saves time and money but also contributes to sustainability.

Complete replacement of POROSTAR® wire mesh laminate

In this method, the damaged woven wire cloth laminate is completely removed and replaced with a new one, while the original flange ring is retained. See for yourself — our before-and-after images of POROSTAR® filter element repairs vividly illustrate how effective the repairs are in restoring original performance:

Advantages of a complete replacement

  • Cost efficiency: Reusing the flange ring lowers material costs and reduces overall repair expenses.
  • Sustainability: Less waste due to the reuse of the flange ring supports environmentally responsible actions.
  • Time savings: Eliminating the need for new flange ring manufacturing significantly shortens repair time.
  • High Quality: The new wire mesh laminate continues to meet strict standards of Haver & Boecker, ensuring maximum performance and durability.

Partial repair of woven wire cloth laminate

In this approach, only the damaged area of the laminate is replaced or repaired, while the rest of the laminate and the flange ring remain intact.

Advantages of partial repair

  • Cost efficiency: Repairing only the damaged section reduces material and labor costs compared to a full replacement.

  • Minimal downtime: Partial repair is faster, ensuring continuous production.

  • Effective restoration: Targeted repairs enable precise and efficient damage correction.
  • High Quality: The new wire mesh laminate continues to meet strict standards of Haver & Boecker, ensuring maximum performance and durability.
