Equivalent to Edwards 19#, 20#, and 70# and Leybold N62H
1.When combined with additives, the Ultragrade® oils give improved vacuum performance, thermal and oxidation stability and rust
inhibition.
2,The anti-oxidants enable the pump to withstand high operating temperatures without oil degradation,extending intervals between oil changes.
Application Of Vacuum Pump Oil
This product is particularly appropriate used in the refrigeration, lighting, electric vacuum, freeze drying, distillation, food packaging, particularly appropriate biological, chemical and other industries.
