ECO 25/6 is a higher viscosity PFPE vacuum pump oil that offers extreme low evaporation loss. This product is suitable as lubricant for rotary and roots vacuum pumps.
PFPE or perfluorinated polyether is a virtually inert material made of carbon, fluorine, and oxygen atoms. Due to its high performance and ability to withstand harsh environments including oxygen, radiation, and other corrosive materials, PFPE is commonly used in the aerospace industry. As with all PFPE oils, ECO-25/6 offers outstanding lubrication properties, zero flash and fire point, excellent compatibility with metals, plastics, elastomers, and is your non-toxic choice for rotary vacuum pumps.
