In order for pneumatic systems to be safely operated, especially braking, air dryers are used. They remove moisture from the intake air and thus reduce the risk of corrosion in the compressed air system. In addition, air dryers prevent the freezing of valves and regulators at temperatures below freezing.
The essential ingredient of the component is a fine granulate (as with dryer cartridges for air conditioning systems): Thanks to its large surface area, this open-pore dryer is ideal to absorb and bind humidity. The granules are located in cartridges which are attached to the air dryer by means of a thread.
The accumulated moisture must be removed regularly – at the latest when the entire surface of the dryer is coated. In order to do this, compressed air from a separate container is blown in opposite direction through the air dryer and discharged to the outside.
Repair shops can rely on quality parts by Ferdinand Bilstein when replacing air dryer cartridges. We offer a large selection of cartridges for numerous truck models – with or without oil separator depending on the version.
In order for the pneumatic components to function, they need air as an energy carrier. The air is compressed by an air compressor and stored in compressed air tanks.
The crankshaft of the compressor is driven by the vehicle engine via auxiliary belts or toothed gears. A downstream pressure regulator determines the amount of pressure generated.
All components must be able to withstand great pressure: If the compressed air generated in the compressor is routed via control valves, a system pressure of approx. 8 bar prevails. For this reason, all pneumatic spare parts are thoroughly tested at febi.
Our certified quality management checks the offered components for different requirements and loads, so that only products of high quality are installed.
