What Compact Filter Technic does

CFT GmbH Compact Filter Technic is a German industrial air-technology company founded in 1999 and headquartered in Marl, North Rhine-Westphalia. It designs, manufactures, and supplies dust extraction, ventilation, air cooling and heating, methane drainage, and air ducting systems, plus digital process monitoring via its Smart Filter Technologie, primarily for underground mining and tunnel construction customers. Core product families include dry and wet dedusters achieving up to 99.99% separation efficiency, patented CTBA dry drilling cuttings suction systems, axial and centrifugal fans (300mm to over 3,700mm impeller diameter including DLK-acquired SATM tunnel jet fans and SARM smoke extraction fans), and the ENERGIFY energy-recovery system. The portfolio spans patented dust extraction and air handling equipment, turnkey engineered installations, and ongoing service, training and maintenance contracts, with hardware typically sold as one-time project purchases supplemented by multi-year service, rental and leasing agreements.

CFT operates as the principal operating subsidiary of the CFH Group, a German holding structure whose 51% majority shareholder since August 2025 is Yancoal International Holding Co., Ltd. (a Yankuang Energy / Shandong Energy company). The CFH Group consolidates complementary subsidiaries including Korfmann Lufttechnik (fans, 100% owned since Oct 2020), DLK-acquired tunnel jet fan and smoke extraction product lines (acquired Nov 2021), AIRONN (Turkish axial fan manufacturer, 51% acquired Aug 2025), the PTC PARFORCE phosphorus-recovery JV, and regional sales subsidiaries in Poland, France, Russia, Kazakhstan, Australia, China (Shanxi Tiandi CFT JV and CFH Shanxi Technology), and Turkey. Distribution is direct enterprise field sales targeting mining operators, tunneling contractors, and infrastructure developers, supplemented by a network of country-level sales representatives across Europe, the CIS, Asia, South America, and Africa. Production is anchored by the Marl facility (over 7,500 m², Europe's largest fan test stand) with new manufacturing capacity added in Shandong, China in December 2025. The business model combines project-based capital equipment sales, multi-year service contracts, and rental/leasing options, with all pricing quote-based and not publicly disclosed.
