Apiezon AP303 is manufactured from high quality polyol ester base stock AP 303 oil is a robust and proven lubricating oil for use in turbomolecular pump bearings.
It offers a range of benefits, including excellent lubricity and long service life with a wide operating temperature range suitable for continuous use at typical turbo pump operating temperatures. AP-303 also has low vapour pressure, meaning that it will not readily evaporate in operation.
It is a proven and robust lubricating oil. Manufactured from a high quality polyol ester base. It is used in turbomolecular pumps with conventional bearings which require a high grade lubricant with low vapour pressure. High-speed bearings such as these, with a low bearing load, require oil with a low viscosity.
The turbo pump oil's polyol ester formulation provides excellent lubricity along with good resistance to ageing, which provides a long service life. It is advised to degass the turbo oil before use to shorten pumping time and prevent foaming.
