What Deltrian does

Deltrian International S.A. is a Belgian air filtration manufacturer founded in 1967 in Fleurus and operated today as a privately-held company under the Alexius family with Jürgen Alexius as Owner & Chief Commercial Officer. The company produces a broad portfolio of air filtration products — pocket filters, compact and rigid filters (including the RPV Energy Saving line), HEPA/ULPA absolute filters, molecular/activated carbon filtration, cartridge filters, ATEX filters, filter boxes, air flow regulators, and the LFC reusable-frame filter — alongside a five-SKU air purifier family (DeltriPure, Mia Air variants) and a protective equipment line of virucidal surgical masks (DeltriSafe+) developed in partnership with Molecular Plasma Group.

Deltrian generates revenue through three mechanics: (i) hardware sales of filters, purifiers, and protective equipment distributed via direct enterprise sales across France, BELUX, French-speaking Switzerland, and international markets; (ii) TFM (Total Filtering Management) managed-service contracts that bundle maintenance, cleaning, and optimization; and (iii) customized filtration projects for industrial gaseous emissions. Pricing is overwhelmingly quote-based for B2B solutions; only mask retail pricing (€29 per box of 50) is publicly disclosed. The company serves 20+ verticals including automotive, hospitals, pharmaceutical, data centers, food industry, airports, railway, cleanrooms, HVAC, and gas turbines, with named customers such as VINCI Facilities, Volvo Cars Gent, Interparking, Uvelia, and Gramitherm.

The company operates production sites in 10+ countries across Europe (Belgium, Slovakia, Italy, Turkey, UK, Lithuania), North America (US), Africa (Morocco), and Asia (China), supported by certifications spanning ISO 9001, ISO 14001, EN 1822, ISO 16890, Eurovent, ATEX, HACCP, VDE, ROHS, TUV, VCA 2-star, and a 2025 EcoVadis Silver Medal. In June 2026, Deltrian partnered with Rivean Capital to accelerate the creation of a European air filtration leader, following its February 2026 acquisition of UK-based Westbury Filtermation Ltd — together signaling a transition from family-owned operator to PE-backed roll-up platform.
