Description
This oil is designed for dry vacuum pumps (claw, scroll, Roots and screw pumps) in photovoltaic industry and also suitable for after-sales maintenance replacement. It features superior thermo-oxidative stability, chemical-corrosion resistance and extremely low evaporation loss. It maintains lubrication performance for long periods under high-vacuum, high-temperature and process-gas-erosion conditions and effectively extends vacuum-pump service life.
