Air compressors are widely used in the auto painting industry, but there are many additional applications for which these unique systems are implemented. One important component that helps compressors function optimally is the air oil separator. Here, the team at Parts Engineering Company, a leading provider of air compressor parts in Maryland Heights, MO, explains how these important parts work.

A Guide to Air Oil Separators

What Are Air Oil Separators?

Air oil separators are components found in air compressors. They remove any trace of oil from the compressed air and return it to the oil sump to ensure clean, pollutant-free air for the intended application. When the separator is broken or otherwise compromised, it could allow air to pass through, which could cause serious issues. For instance, in the auto painting industry, it’s essential to make sure no oil is secreted, because it could damage the paint job and become a hazardous airborne particle.

How Do They Work?

There are a few different types of separators, each of which removes oil in its own unique way. Traditional separators are made from glass fiber and feature a wrap style that removes oil from compressed air. Newer pleated separators can process twice as much air and use a wave-like structure to separate oil. Deep filter separators also have an increased airflow capacity and use different types of borosilicate glass wrapped onto a tube to trap oil.

To keep your air compressor in top working order, it’s essential to replace your air separator as needed. While life spans vary by type, in general, a separator can last for 4,000 to 6,000 operating hours under normal conditions. However, if you suspect an issue with your separator, replace it before then.
