The best way to protect against contamination is to eliminate it as soon as possible or, ideally, to prevent it from entering your system at all. This can be ensured on the one hand by using verified and energy-efficient hydraulic oil, clean filling accelerators and low-maintenance filter technology.

Hydraulic oils, requirements and classifications.
Hydraulic oils are filterable hydraulic media required to transmit energy. This involves the oil being transported by a pump to the designated pipes whereupon a piston moves. This strong lever allows great forces to be generated despite comparatively low pump capacities.
The most important requirements include lubricity, hydraulic system cooling, corrosion and wear protection and optimized viscosity properties. Mineral oil-based and aging-resistant hydraulic oils standardized in accordance with performance class DIN 51524 (1,2 and 3) and DIN ISO 15380 in Germany are generally used:
- H: Hydraulic oils with no additives
- HL: Hydraulic oils with oxidation inhibitors and corrosion protection
- HLP: HL hydraulic oils with additional wear protection
- HVLP: HLP hydraulic oils with additional viscosity boosters
- HLPD: like HLP, but with additives for boosting particle transportation (detergent effect), dispersal capacity and for boosting corrosion protection
- HLP-AF: zinc- and ash-free hydraulic oil
- HVLPD: the improved viscosity index and detergent effect combine the advantages of HLPD and HVLP
