What LTA Lufttechnik GmbH does

LTA Lufttechnik GmbH is a German industrial air filtration specialist headquartered in Nordrach, Germany, operating as an integral sister company of the JUNKER Group (Erwin Junker Maschinenfabrik GmbH). The company designs and manufactures electrostatic, mechanical, and dry-separation filtration systems that remove oil mist, emulsion mist, dust, and smoke from metalworking and industrial production environments, handling particles between 0.001 and 100 micrometers across extraction capacities from 600 to 36,000 m³/h. Its product portfolio spans compact units (E 80, M 60), standard units (E 120, M 120), high-capacity electrostatic filters (E 480, E 720), dry separators (Md 90 to Md 600), and central extraction systems (E 800 through E 2400), complemented by a safety technology line including fire dampers, air shut-off valves, fire extinguishing systems, and control panels certified by the IBExU Institute for Safety Technology. The company reports a cumulative installed base of 6,000+ electrostatic, 4,000+ mechanical, and 1,000+ dry-separator customers, with safety systems protecting more than 3,000 machine tools worldwide.

LTA's underlying technology combines electrostatic precipitation (using ionization zones and electric-field deflection to achieve up to 99.8% separation efficiency on oil and emulsion mist) with mechanical separation (inertial separation plus filter bags/cartridges with CIP/HCIP automatic pneumatic cleaning, ATEX compliant). Washable and reusable filter elements support operating cost reduction and sustainability, while FEM-based flow simulation and 3D collision checking underpin engineering deployment. The company holds ISO 9001 and ISO 14001 certifications, complies with TA Luft emission standards (20 mg/m³ limit), and holds IBExU safety certifications across its machine-tool safety portfolio.

The business model combines custom-engineered hardware sales (configured systems for industrial manufacturers and OEM-embedded integration for machine builders, including color matching, electrical interface customization, and country-specific compliance), recurring spare-parts and consumables revenue through an online shop, and professional services including 24/7 installation, maintenance, repairs, industrial washing, ultrasonic cleaning, and flow simulation engineering. Pricing is custom quotation-based, varying by configuration, capacity, stages, and installation requirements, with multi-year service contracts. Go-to-market is direct enterprise field sales organized by regional sales managers across Germany, Austria, Switzerland, France, Czech Republic, Poland, Hungary, Italy, and the Baltics, augmented by JUNKER Group offices in the USA, Mexico, Brazil, India, and China, OEM partnerships with machine builders, an online shop for consumables, and event-driven demand generation through trade shows such as AMB 2026. Named customers include FRAISA (precision tools), Hammelmann (high-pressure pumps), Kratzer (metal forming), and Erdrich Umformtechnik (metal forming).
