Clean Air through Innovative Filter Technology
High-efficiency particulate filter systems for combustion plants. Developed and manufactured in Triesen, Liechtenstein — for over 40 years.
Four Decades of Excellence
1985 — 2026
Since 1985, at our Triesen site, Neoxan AG has been developing and manufacturing innovative filter systems for exhaust gas purification. What began as pioneering work in Liechtenstein is today an established reference across Europe. Four decades of research, development and consistent quality — that is what we stand for.
Technology that Makes the Difference
Our patented Kapillara™ technology combines the highest filter efficiency with innovative energy recovery.
Kapillara™ System
Patented 50mm mineral inner lining with up to 1000°C heat resistance.
Residual Heat Recovery
Integrated heat exchangers recover up to 25% of energy.
99% Filter Efficiency
Highest filter performance at 99% of boiler operating hours.
Low Maintenance
Robust stainless steel construction. 2 years free service included.
Condensation-free
Safe low-temperature operation without condensation problems.
Environmentally Friendly
Reduces particulate emissions to a minimum. Active contribution to climate protection.
A Look Inside
The patented Kapillara™ technology in detail: Our filter systems combine state-of-the-art filter technology with a sophisticated heat recovery system.
- High-efficiency filter elements
- Integrated heat exchanger
- Automatic condensate evaporation
- Robust stainless steel construction
Condensation & Energy Recovery
Neoxan AG builds more than particulate filters. We deliver complete systems for flue gas condensation and heat recovery — capturing additional energy from every cubic metre of exhaust air. This cuts both emissions and operating costs.
- Flue gas condensation to capture the latent heat in water vapour
- Integrated heat exchangers with measurable energy recovery
- Fabric filter systems for the highest separation rates
- Custom-built and produced at our Triesen site
