This expansion of the product line can be used in almost all industries. The service unit is absolutely focussed on core functionality and offers all common basic functions for compressed air supply, such as filtration, control and air lubrication. It is completely connectible to the existing line of products. The compressed air preparation unit is also extremely easy to assemble: assembly and conversion or supplements can be done by the customer himself without disassembling of the unit. Easy-to-understand, clearly structured components are visually integrated in modern systems manufacturing as very compact units.
