Model: HFV-K3、K4、SK
Describe: Lower saturated vapor pressure, narrow distillation range, large molecular weight and fast pumping speed.
Introduction: It can be used as the working fluid of diffusion pumps used in electronics, aerospace, nuclear industry and other industries.
Package: 3.5kg/can, 4 cans/box
The vacuum oil produced by Huifeng Enterprise is made of high-quality base oil and imported additives. It is an ideal lubricating material and is widely used in my country's military enterprises, display industry, lighting industry, solar energy industry, coating industry, refrigeration industry, aerospace, etc.
※ Lower saturated vapor pressure, narrow distillation range, large molecular weight, and high pumping speed.
※ When the oil is heated to boiling, the oil will be ejected at supersonic speed and can achieve vacuum quickly.
※ Reasonable chemical composition, good oxidation stability and thermal stability.
※ HFV- K has a low oil return rate, and the oil vapor can quickly condense into new working fluid after encountering the cold wall.
※ Low saturated vapor pressure, narrow distillation range, high molecular weight and pumping speed.
※ When heated to its boiling point, the oil will eject in supersonic speed to create a vacuum environment rapidly.
※ Reasonable chemical compositions, perfect oxidation and thermal stability.
※ Low back-streaming rate, oil vapor will condense into new fluid as soon as it touches cold wall.
※ HFV-K diffusion pump oil is mainly used for steam flow oil diffusion pumps, and diffusion pump oils of different molecular weights can be selected according to the requirements of the reaching pressure.
※ Suitable for vacuum distillation, vacuum smelting, vacuum coating, vacuum furnace, etc.
※ Can be used as the working fluid of diffusion pumps used in electronics, aerospace, nuclear industry and other industries.
※ Suitable for vapor diffusion pumps, it is available according to the final pressure only.
※ Applicable to vacuum distillation, vacuum metallurgy, vacuum coating, vacuum furnace, and etc.
※ Also be used as working fluid of diffusion pump in industries, such as electronics, aeronautics, nuclear and etc.
