Screw Compressor Oil Separator

1.How does an air compressor filter work?

Air line filters work by straining air to trap solid particles and separate liquids from compressed air. To clarify the process, it helps to identify the main components found in an air compressor filter:

Inlet: The air compressor intake or inlet is where air enters the filter. There is an internal cap that forces air downward into a spiral. It’s important to get the right size inlet rather than using a filter smaller than the line.

Filter cap: This component directs airflow through the filter. You can tell the direction of the air by the arrow on the outside of the filter, which also prevents you from installing it backward.

Air path: This is the actual path the air follows as it spins like a cyclone and passes through the air filter itself.

Filter discharge: This orifice allows air to leave the filter, and it should match the inlet size. If the filter discharge is too small, it will restrict the flow of air.

Filter element: The filter itself is what takes contaminants out of the air, catching particulates over time. Eventually, filters become clogged and must be cleaned or replaced.

Filter bowl: The bowl is the biggest part of the filter that you can see. It is connected to the cap and is threaded or twisted and locked into place.

Filter quiet zone: The contaminants, water and oil collected by the filter all end up in the quiet zone at the bottom of the filter. You will usually find a barrier hanging from the filter bottom, preventing debris from being reintroduced into the air.

Drain: Collected contaminants and debris have to be drained. Many filters must be drained manually, but others have float-operated or electric auto drains.

In the first stage of filtration, compressed air passes through a mesh filter. This creates a clumping effect where the larger particles are trapped by the filter, and the water condenses into bigger droplets then travels to the separation chamber.

The compressed air slows down, allowing particulates to condense on a pad with honeycomb-like qualities. This facilitates the movement of droplets to the drain. After entering the drainage system, droplets are discharged through the drain valve. This stage of filtration removes a majority of the oil, large particles and water droplets.

 2.Function: 

The function of the oil-air separator is to separate the oil in the compressed air to make the compressed air cleaner. After the oil is separated, it passes through the oil return pipe to make the oil circulate in the compressor. The oil and gas separator produced by Sanya uses anti-corrosion materials, fine welding technology and the use of the latest double-sided adhesive to ensure that the oil has a high mechanical strength, and the oil and gas separator can work normally at a high temperature of 120 degrees Celsius.
The skeleton and flange of Thirty Asia's oil and gas separator are made of 316L stainless steel, and the filter layer adopts 4-layer filtration, with a filtration accuracy of 0.1 micron, an oil content of less than 3PPm, and a service life of thousands of hours.
