A medium-sized company of more than 25 years' standing, we have made our name nationally and internationally in the fields of air filter technology, workplace safety and environmental protection on the basis of an ecological and socially responsible company philosophy. The "door within a door" design of our electrofilter series has become an international benchmark for technically sophisticated and easy-maintenance filter systems. For years, the continuous monitoring of developments in the design and performance of modern machine tools has given rise to more and more new electrofilter series, often in collaboration with the mechanical designers, and with the form adapted to the machine tool design. This also calls for a new design of the filter equipment, primarily the ionizer and collector cells. Today, DSL Air Technology boasts the world's largest electrofilter modification in the sector.
