The Company

Die FILTRONtec GmbH, headquartered in Starnberg (Germany), was founded in 2000 by two shareholders and has developed into a market leader in its niche market segment through continuous innovation and growth.
From pre-planning to commissioning, FILTRONtec is a reliable partner when it comes to ultra-modern and efficient air filter systems for road tunnels and other building structures. We accompany your planning work, supply and install tailor-made filter technology and, if required, also take over the operation and maintenance.

Our company´s head quarter is located in Starnberg near Munich and the engineering branch office at Wolfen, Saxony-Anhalt. Overseas subsidiary companies are located in Australia, Hong Kong and Spain.

Our team of qualified and experienced employees at home and abroad and an international network of suppliers guarantee the high quality of our filter systems.

FILTRONtec has been certified by TÜV since 2008 according to DIN ISO 9001.

Our products are used worldwide

Increased traffic, increasing environmental awareness and responsible health protection conscience are some of the reasons for the growing interest in our air filter systems for road tunnels and underground garages.

In 2004, FILTRONtec was chosen together with only two other competitors in a worldwide technical qualification competition run by the Road and Traffic Authority (RTA) in Australia among 13 applicants for the planning and construction of a pilot filter system in a tunnel in Sydney. In 2009, the contract was awarded to FILTRONtec, and in 2010 the filter plant went into operation.

From 2007 to 2008, FILTRONtec installed various air filter systems in the M30 tunnel in Madrid.

Since 2015 we have installed eight air filter systems, to treat 1500m3/s of road tunnel exhaust air, in the Central-Wan Chai Bypass tunnel in Hong Kong.
