STF Filters

What STF Filters does

STF Filters, legally Sistemas De Filtrado Y Tratamiento De Fluidos, S.L., is a Spanish manufacturer of water filtration and hydraulic infrastructure equipment founded in 1935 and headquartered in Monzón, Huesca, Spain. The company designs and produces screen filters, disc filters, gravel filters, hydrocyclones, surge tanks, penstocks, flap valves, dismantling joints, expansion joints, and modular fertigation systems, serving three primary end-markets: agricultural irrigation, industrial process water, and municipal water infrastructure. Notable project deployments include the FIFA Albayet Stadium in Qatar, a stormwater reuse system for the NYC Sanitation Department in Brooklyn, and a livestock water filtration system at Peculo Farm in Spain. The portfolio is differentiated by configurable modular designs (e.g., STFert HF with 2-8 independent injection channels), hydraulically-driven fertigation pumps that operate without electricity, multi-standard compliance (ISO 9001, ISO 14001, ISO 3834-2, NSF, ACS, WRAS, ASME U-Stamp, AENOR Towards Zero Waste), and a 90-year track record of custom-engineered delivery across 100+ countries.

STF operates under MatHolding's MatWater Division alongside sister brands VICAN (metallurgical water conveyance components) and YAMIT (advanced filtration), with a sales and support office in Beijing extending its presence into Asia-Pacific. Revenue is generated almost entirely through project-based hardware sales of filtration and hydraulic infrastructure equipment, supplemented by engineering services for custom system design and installation support. Pricing is quote-based, determined by project specifications, configuration, quantity, and geography, with no publicly disclosed price tiers or standardized billing. The company is privately held with no public listing, no disclosed funding rounds, and 51-100 employees.
