Special oil for screw vacuum pump
Short Description:
The state of the lubricant will change according to the power loading and unloading pressure of the air compressor,the operating temperature,the original lubricating oil composition and its residues,etc.
Product Introduction
Good oxidation stability extends system life.
●Low volatility reduces maintenance costs and refills.
●Excellent lubricity can improve work efficiency and reduce operating costs.
●Good anti-emulsification performance and good oil-water separation.
●Basic oil with narrow hydrophobicity and low product saturated vapor pressure ensures that the pump can quickly obtain a high degree of vacuum.
● Applicable：cycle:5000-7000H.
● Applicable：temperature:85-105.
