Features of Aifaco VDN bipolar rotary vane vacuum pump:

1. Low noise, low vibration, the working environment will not be affected

2. Built-in high-efficiency oil mist filter, the discharged gas does not contain oil mist

3. Air cooling is adopted, but the larger vacuum pump is equipped with a cooling air duct, which uses a fan to cool the lubricating oil in the air duct to improve the cooling effect

4. The exhaust air volume is strong, and the ultimate vacuum is as high as 6.7*10-1pa.

5. The built-in check valve and gas ballast valve can avoid the reverse flow of the oil caused by the reverse of the pump after the shutdown and avoid the water vapor in the air being compressed and condensed into water spots in a high vacuum environment, resulting in the emulsification and deterioration of the lubricating oil.

Precautions for refueling of Aifak vacuum pump:

Avoid direct contact with lubricating oil to prevent skin irritation. Containers and tools such as oil extractors and oil pots must be cleaned and wiped before each refueling. Before changing the oil, the machine must be rinsed with solvent, and water-soluble cleaning agent must not be used. It is strictly forbidden to directly discharge waste oil into the ditch and pour it into the soil to prevent pollution of the environment. The vacuum pump oil chamber can be stored upright, with the barrel facing up for easy extraction.
