GKD: high-tech production of EGR filters

Meeting the requirements of modern engines is like squaring the circle. They must be agile and powerful, yet also environmentally friendly and economical in order to survive in the fiercely contested global market. Exhaust turbochargers and low-pressure exhaust gas recirculation (LP EGR) have therefore become the standard for diesel engines in modern passenger cars. Virtually all leading manufacturers are now using the three-dimensional Volumetric mesh from GKD – GEBR. KUFFERATH AG (GKD) to protect their turbochargers from mechanical damage caused by particulate matter in the LP exhaust gas filter. This filter medium, produced from high-temperature-resistant stainless steel, offers 70 percent greater volume porosity than conventional square mesh in the same wire diameter. It thereby guarantees minimal loss of pressure in the exhaust gas recirculation system, while securing maximum particle retention. The special mesh is produced using automated, ultra-modern manufacturing processes with accompanying digital quality control. As the worldwide technological leader in the field of technical weave, GKD guarantees compliance with the strict product safety and reproducibility requirements.
