Vision and Philosophy

Place your trust in us!

Just as more than 3.000 customers all over the world already do!

„In urban agglomerations, the ever-increasing traffic
threatens to become an even greater burden on people
and environment. Today all over the world giant tunnel
projects are being planned or already built to prevent collapse of transportation. With our ECCO filter systems we can contribute to maintain a healthy living space for the abutters.

In the future, use of tunnel filters might even become a prerequisite for tunnel projects to be approved and realized in the first place.

Protecting people and environment, that is our mission!“

Ing. Heinz Aigner
Managing Director
