Four product families, one goal: maximum separation at minimum energy consumption.
A family business with vision
What began in 1962 with three employees and a workshop for oil filters is today one of the leading medium-sized filter manufacturers in Europe. We are independent, owner-managed and invest around 6% of our turnover in research and development every year.
Our customers value short distances, quick decisions and contacts who know their plants.
For your industry
Every industry has its own filtration requirements. We know them.
A good filter goes unnoticed. It makes sure everything else works — day and night, for years.
