Air dryer cartridges. Dry. Filter. Protect.

Safe braking every time, thanks to cleaner compressed air systems. Air dryer cartridges with and without oil separators from Knorr-Bremse, a market leader in filter technology.

A dry season for your braking system

Compressed air and moisture don’t get along, especially not in the braking system of a commercial vehicle. Aerosols entering the pneumatic system can accelerate wear and shorten system service life. Don’t let it come to that! Air dryer cartridges from Knorr-Bremse reliably dry compressed air, thereby protecting the entire braking system from freezing, internal corrosion and reduced braking performance. Thanks to their outstanding materials and optimal technology, Knorr-Bremse air handling systems ensure brakes are supplied with compressed air efficiently and precisely. Anytime!
