Compressors come with air filters that trap dirt, debris, and airborne particulates that could damage the machine. Failure to change them regularly often comes with a hefty price: premature motor malfunction. Here’s a closer look at what these filters do and how often they should be replaced.

What Is an Air Filter?

Air filters are relatively inexpensive but essential components of an air compressor motor. As they become clogged with dirt, they can obstruct proper airflow inside the machine, putting extra strain on the motor and resulting in less-efficient performance. A simple filter has an element that traps contaminants on its walls. The finer the filter element material is, the more particulates it traps and the quicker it gets clogged.

Other components of an air compressor filtration system include an inlet, filter cover, and path for directing air to pass through the filter element. A filter bowl contains everything in its place, while the quiet zone collects any filtered debris that can be drained out by dislodging the plug.

How Often & How to Change It

The frequency of replacing a filter depends on the environment in which the compressor operates — the cleaner the surroundings, the fewer changes are needed. For optimal performance, have the filter checked and changed twice a year, at the minimum.

Before dismantling the air filter, brush the area around the cover to remove any contaminants that might enter the intake or path. Then, take out the cover or cap to get to the filter element. Protect the air intake with a clean cloth or tape before disassembling the element. Next, wipe inside the cover with a clean cloth; you can also wash and dry it for a more thorough cleaning. Install the new filter and its element, then replace the cover securely. Avoid using compressed air to clean the filter element; instead, replace it altogether.
