An air compressor is a vital piece of equipment that helps you maintain tire pressure and operate a variety of tools around your shop. However, to keep it running properly, you need to maintain it well, and this often includes replacing the compressed air filter.  Parts Engineering Company, a respected service and parts company in Maryland Heights, MO, explains below when you should change the compressor's air filter.

When Should You Replace Your Air Compressor’s Air Filter?

Do You Require Filtration?

First, determine if you actually need to filter your compressed air. If not, you may be able to remove any redundant filter that was routinely installed at the time of or after the compressor's purchase. If it's unnecessary, it may simply be a waste of time and resources to maintain the filtration system.

Check the Pressure Differential Gauge

The compressor's pressure differential gauge measures at two points—before and after the air filter. If there is a noticeable difference between the two, that difference is likely due to a clogged filter. Replace the air filter, and the pressure differential should disappear. Note that the differential may not be noticeable unless the compressor is set to maximum flow.

Check the Last Service Date

If the compressor does not have a pressure differential gauge installed, look for a tag on it listing the filter's last service date. The manufacturer likely lists, in the compressor's service manual, the maximum amount of time you should wait between air filter changes. However, if the compressor receives a good deal of use, change filters more frequently.

The information above should help you understand when it's time to replace the air filter on your compressor and, through proper maintenance, keep it in top condition for as long as possible.
