Oil-Free Air Compressor Supply for Germany and the EU
PED, machinery/electrical conformity and technical documentation must be assigned in the supply contract.

Pressure Equipment Directive
Directive 2014/68/EU applies to design, manufacture and conformity assessment of pressure equipment and assemblies with maximum allowable pressure greater than 0.5 bar, subject to exclusions and classification rules. Determine whether the compressor package is supplied as an assembly, which components are pressure equipment, who is the manufacturer for CE purposes and which conformity-assessment modules apply.
Documentation and integration
Define EU Declaration of Conformity responsibilities, technical file, risk assessment, manuals, language, electrical compatibility, noise data and applicable harmonized standards. Germany commonly uses 400 V, 50 Hz three-phase systems, but the actual site supply must be confirmed.
Project boundary
Always request the final general arrangement, wiring diagram, P&ID, pressure-equipment documents, performance statement, packing data and commissioning plan before shipment. The catalogue table is a starting point, not a conformity declaration.
For a medical oxygen project, clarify whether the compressor is feed air for a PSA/VPSA plant or medical air delivered to a patient pipeline. These are different duties. The machine must not be used to compress oxygen-rich gas without an explicitly engineered oxygen-service package.
