Since the company was founded in 1993, we have been developing and producing environmentally friendly air filters for supply and exhaust air purification in ventilation and air conditioning systems, dust removal and painting systems using only recyclable materials.
Our self-obligatory concept consistently avoids non-regenerable adhesives, which cause disposal problems, as well as environmentally harmful two-component encapsulants or other isocyanate-containing substances. Therefore, all components of our filter systems can be disposed of separately in an environmentally friendly way. Due to the continuous expansion of our product range and the use of computer-aided production facilities on a now expanded production area of more than 1800 m², we have been one of the largest, owner-managed air filter manufacturers in Europe for more than a decade, with a focus on consistently high quality.
