high-performance industrial applications and environmentally sensitive areas
• Clarity Synthetic Hydraulic Oils AW are designed to meet or exceed the performance requirements of conventional anti-wear hydraulic oils, in severe,
high-output applications such as axial piston pumps, while offering an additional level of safety in case of leaks or incidental discharge to the environment
• Many hydraulic systems are required to operate in environmentally sensitive areas where leaks or spills of hydraulic fluid may result in contamination of the soil or nearby waterways. Conventional anti-wear hydraulic oils are formulated with metal-containing performance additives which can persist in the environment in the event of leaks
• The anti-wear performance of Clarity Synthetic Hydraulic Oils AW makes them suitable for high performance industrial applications utilising axial piston pumps where pressures may exceed 5000 psi
• High level of oxidation stability is especially applicable in high efficiency (high speed, high temperature, high output) applications where severe stress is placed on the hydraulic fluid
