MCLANAHAN AND DIEFENBACH LAUNCH PATENT-PENDING QUICK-CHANGE SYSTEM: Revolutionary Technology Redefines Filter Cloth Maintenance with Speed, Safety, and Efficiency
Hollidaysburg, Pa., March 25, 2025 — McLanahan, in collaboration with its sister company Diefenbach, is thrilled to introduce the QUICKCHANGETM system—a patent-pending innovation set to transform filter press maintenance. Engineered for speed, simplicity and safety, this groundbreaking technology streamlines filter cloth replacement and filter plate inspection, slashing downtime and boosting operational efficiency. The QUICKCHANGETM system will be available through McLanahan, Diefenbach, and Eagle Iron Works starting in 2025.
The QUICKCHANGETM’s design reimagines filter cloth maintenance with an innovative design that allows cloths to glide effortlessly in and out during replacement. Unlike traditional methods requiring extensive manual labor or specialized lifting equipment, QUICKCHANGETM enables operators to perform maintenance at ground level in minutes—reducing the industry-standard replacement time of 10-20 minutes per cloth to just 1-2 minutes. This dramatic reduction in changeout time minimizes downtime and maximizes productivity.
Safety is a cornerstone of the QUICKCHANGETM system. By eliminating the need for personnel to climb onto or inside filter presses for cloth changeout, the risks associated with working at heights or in confined spaces can be drastically mitigated. The streamlined process also reduces dependence on slow-moving overhead lifting equipment, further enhancing safety and efficiency. Filter cloths can be removed for quick cloth or filter plate inspection at eye level without the need to lift plates out of the filter press.
Beyond speed and safety, QUICKCHANGETM delivers cost-saving innovation. Traditional systems require replacing filter cloths on both sides of a plate when one fails, but QUICKCHANGETM allows operators to replace only the damaged side, cutting material waste and long-term maintenance costs. A specially designed feed shoe protects high-wear areas around the feed hole, extending cloth lifespan and ensuring consistent, high-performance filtration.
“Efficiency and safety drive everything we do,” said Cory Jenson, Executive Vice President of Sales and Business Development at McLanahan. “Teaming up with Diefenbach—a pioneer in liquid-solid separation since 1907—we’ve created a game-changer. QUICKCHANGETM gets plants back online faster and safer, slashing downtime from filter cloth changeouts.”
Alessandro Felicani, Managing Director of Diefenbach, added, “Filter cloth replacement has long been the leading cause of downtime for filter presses in the mining, aggregates, and water treatment industries. With QUICKCHANGETM, we’ve reduced that downtime for cloth changeout by a factor of ten or more.”
Building on McLanahan’s and Diefenbach’s legacies of innovation, the QUICKCHANGETM system is tailored for filtration in industries like mining, aggregates, chemicals, and wastewater management. It will debut globally in April 2025 at Bauma in Munich, Germany, and Expomin in Santiago, Chile. Attendees can witness and participate in live demonstrations and experience how this technology redefines filter press operations.
