ANDRITZ successfully launches new disc filter: the PrimeFilter D


International technology Group ANDRITZ has successfully launched the new PrimeFilter D as cutting-edge technology in thickening and fiber recovery.

The new disc filter is perfectly suited to all system applications for many different pulp types and leads the way for upgraded performance and reliability in fiber processing.

The PrimeFilter D builds on ANDRITZ disc filter technology, which has been well proven over decades, and brings together several key technological innovations in one unit to improve throughput and reduce both investment and operating costs:

  • HHw technology for advanced feeding and optimum flow conditions within the filter. Thus, the PrimeFilter D can handle higher feed consistencies and higher-freeness pulp, even in the most demanding applications.
  • CC bagless sectors, offering significant improvements in terms of operation thanks to very homogeneous fiber mat build-up as well as fast mat knock-off. The special design of the sectors eliminates the need for a filter bag and reduces maintenance to almost zero.
  • Two-level shaft sealing: The innovative, double sealing arrangement is easily accessible and ensures greater reliability and superior filtrate quality.

Peter Clewes, Vice President Stock Preparation and Recycled Fiber Systems within the Paper, Fiber and Recycling Division at ANDRITZ, explains: “The innovative PrimeFilter D has already been very well received on the market. Several units are in the process of being started up, and we have received further orders from leading producers. This is proof that we have met our targets to improve performance and reduce maintenance when it comes to disc filter technology.”​​​​​​​
