Parker portable and offline filtration units are the ideal way to pre-filter, transfer, or condition fluids in existing systems. Fluid should always be filtered before use because new fluid is not necessarily clean. Most new fluids are unfit for use due to high initial contamination levels, which can result during processing, mixing, handling, and storage. Whether you are transferring new fluid into a hydraulic system, or cleaning up fluid in an existing system, use Parker offline or portable filtration systems to ensure your system can perform its maximum capacity.
