The function of the compressor oil mist fan

There is an oil mist fan on top of the centrifugal compressor’s oil tank – what is its purpose? When will it start? Seeking advice from experts
Remove water vapor, oil, and gas from the fuel tank in a timely manner to prevent emulsification. Another function is to create a slight negative pressure in the fuel tank, which facilitates oil return.
The main function of an oil mist fan is to create a vacuum or maintain a slight negative pressure in the oil tank; when connected to an oil and vapor recovery system, it also serves to recover such oils and vapors, making it an environmentally friendly and energy-saving device.
Its function is to create a vacuum at the top of the fuel tank, which facilitates the return of oil
In addition to the point mentioned by those upstairs about creating a negative pressure to facilitate oil return, another possible reason is safety. A negative pressure is created, preventing the light components dissolved in the lubricating oil from escaping into the vicinity of the equipment. This is especially important for equipment installed indoors, as leaks can be extremely dangerous.
Removing water vapor and oil fumes reduces the pressure in the tank, preventing high return oil pressure, poor return flow, and heat accumulation in the lubricating oil; it is generally used in combination with inert gases to isolate the tank
Reducing the backflow resistance: at our site, when the oil mist fan stops operating, the number of leaks in the oil system of the unit itself increases significantly
Keep the fuel tank under negative pressure to separate cooking fumes. It needs to be started before turning on the device.
First, it extracts the oil and gas from the tank to prevent their accumulation and the formation of explosive gases; second, it creates a slight negative pressure in the tank to facilitate smoother oil return
On the side of the centrifugal compressor, the main goal is to maintain a certain negative pressure in the oil tank and gearbox in order to prevent oil leakage.
