Roto Z: Enhanced Cost-Efficiency and Storage Stability
Roto Z delivers superior cost-effectiveness by doubling drain intervals compared to conventional lubricants, significantly reducing maintenance frequency and operational costs. Furthermore, it incorporates the functional properties of a preservative mineral oil, enabling extended on-site storage for several months without compromising performance or stability.
| Features | Benefits | |
| Excellent anti-wear properties | Roto Z contains proven anti-wear additives to be effective throughout the range of operating conditions. | This load carrying capacity is particularly important because oil-free compressors are driven by gears, requiring oils with antiwear properties reducing gear teeth and bearing wear. |
| Thermal stability | Roto Z is thermally stable in severe conditions of load and temperature. | The oil has a high resistance to degradation and sludging. |
| Oxidation resistance | The good oxidation control minimizes the formation of aggressive corrosive acids, deposits and sludge. | This oxidation resistance will reduce your operating costs. |
| High viscosity index | Oil viscosity remains at amore stable level, even at high temperatures. This means lubricating efficiency is maintained under varying conditions. | Keeps working hard, whatever the conditions, even at high operating temperature. Increases the bearing lifetime and reduces the general danger in the oil circuit. |
