Reasonable composition, stable chemical character for special gas
Properties of ultimate pressure, back stream rate , volume flow rate are similar to silicon oil and ester oil, not easy for residue gas to produce insoluble isolate film to have effect on vacuum unit
Excellent oxidation stability to reduce residual and peck, lessen frequency of changing oil, save cost of operation
Application
Suitable for variety of mechanical vacuum pump inside or outside
Can be used in circumstance of temperature from ¨C25¡æ to 100¡æ
Applied for special gas such as Ar, NH3, H2, He, N2, CO2, SO2, H2S
