Deltrian International S.A.

What Deltrian International S.A. does

Deltrian International S.A. is a privately held Belgian air filtration company, founded in 1969 and headquartered in Fleurus, Walloon Region. The company designs, manufactures, and services industrial air filtration products — including filter media rolls, rolling filters, pocket filters, compact/rigid filters, high-temperature filters, HEPA/ULPA absolute filters, molecular filtration, cartridge and ATEX-certified explosion-protected filters, plus mounting hardware, air flow regulators, air purifiers, and CO₂ detectors — and complements this hardware catalog with two service lines: TFM® (Total Filtration Management) recurring service contracts and Smart Filtering carbon-footprint reduction support. The company's newest proprietary offering, LFC, was launched in 2026 and is positioned as a breakthrough air purification platform.

The business serves 18 industry verticals spanning airports, automotive and paint booths, hospitals, pharmaceuticals, cleanrooms, data centers, food industry, gas turbines, general industry, rail, HVAC, commercial buildings, and educational institutions. Go-to-market is enterprise-direct and sales-led, with field sales supported by sector-specific expertise, technical consultation, and compliance-driven selling into regulated environments; distribution is handled through wholly-owned subsidiaries and production sites in Belgium, Lithuania, the United States, Morocco, and China. Products are validated against Eurovent, EN 1822, ISO 16890, ISO 9001, ISO 14001, ATEX, CE, VDE, ROHS, TUV, and HACCP standards, and enterprise customers include VINCI Facilities, Gramitherm, Air Ambiance, and an unnamed Major French Manufacturer.

The revenue model combines hardware sales (one-time filter purchases), recurring TFM service contracts, managed-services revenue from Smart Filtering, and bespoke project work, with all pricing quote-based rather than publicly listed. Corporate activity in 2025–2026 has been notable: the founder Klaus Alexius was honored in 2025, the Lithuanian subsidiary was recognized as fastest-growing company in Skuodas (January 2026), Westbury Filtermation was acquired (February 2026), TFM Belgium teams achieved VCA 2-star certification (March 2026), the LFC product was launched, and a strategic partnership with Rivean Capital was announced on 25 June 2026 — together signaling an active consolidation and international expansion phase under private equity sponsorship.

Broad incumbents

• MANN+HUMMEL: Large German filtration group covering air, liquid, and automotive filtration. Competes with Deltrian in industrial air filtration and OEM filtration, but at significantly greater scale and with a broader portfolio outside Deltrian's core air focus.
• Parker Hannifin: Large US-listed industrial conglomerate with significant filtration and air quality product lines. Competes with Deltrian in industrial air filtration as part of a much broader portfolio across motion and control technologies.
• 3M (Filtration / Separation & Purification Sciences): Diversified industrial giant with a major filtration business spanning HVAC, cleanroom, and industrial air filtration. Overlaps with Deltrian in HEPA and HVAC filtration products, though 3M's much larger scale and broader portfolio make it a broad incumbent rather than a direct specialist peer.
• Donaldson Company: US-listed filtration manufacturer serving industrial and engine filtration markets. Overlaps with Deltrian in industrial air filtration and gas turbine inlet filtration, with much greater scale, public financials, and global reach.
