If you use an air compressor for anything from auto repair to painting, you should have a basic understanding of the parts it uses to get the job done. This knowledge can help you identify issues and seek the necessary repairs or replacements so that you can get it back up and running quickly. The air oil separator is one component that’s essential to a compressor’s operation. Here’s what you need to know about it.

Purpose

Air compressors use oil to lubricate moving components like ball bearings. This means that oil gets mixed with the air inside the machine, but that air eventually needs to exit the compressor. Air oil separators are essentially filters that separate oil from the air as it gets pushed out of the machine.

How It Works

Most air oil separators consist of a cylindrical filter. The air and oil mixture is injected into the center, and most of the oil ends up on the sides of the cylinder and collects at the bottom. The remaining air is pushed through a filter that stops any remaining oil particles from getting through. The vessel also collects excess oil and returns it to the compressor so that it can continue to lubricate the moving parts inside.

Why It’s Necessary

First, the separator prevents contamination in the air that gets pushed out of the machine. This protects any other tools you’re working with from getting gummed up with oil particles. It also keeps the oil inside the air compressor, where it must lubricate moving parts and reduce friction. This prolongs the life of your equipment and reduces the amount of maintenance needed.
