KOCLEAN-05 – Compressor Cleaner & System Flush

KOCLEAN is a premium quality synthetic fluid designed to dissolve varnish and solubilize sludge from rotary-screw air compressors during operation. It can also be used as a system flush when changing-over from mineral to synthetic oils in order to reduce contamination due to oil carry-over. Regular use of KOCLEAN will help you get the most out of your synthetic oil and your compressor by removing varnish and reducing operating temperature.
