Syncomp US Rvn no : 1

Super premium synthetic compressor fluid

Syncomp US fluids are entirely synthetic, have a high biodegradability rate, and don't harm the environment. Additionally, they have far superior thermal and oxidation stability, longer fluid lives, and properly combine with OEM polyglycols. As a result of Syncomp US ability to mix with PAGs, flushing of compressors is not required. The additional benefit of this is that polyglycol-filled compressor topping off is permitted until predetermined change intervals.


For all screw compressor applications where excellent cleanliness, high wear protections, and lengthy drain intervals are required, Syncomp US is a specially developed product. Perfect blending with OEM polyglycols.
