Any time a compressor is used in an environment where abrasive dust might get sucked into the compressor, you need an air filter. Abrasive dust in the cylinders of the compressor wears the pump out prematurely.
This not only causes you to have to rebuild your compressor sooner than you should, it saturates a few loads of expensive abrasive with oil mist before you figure out what the problem is. Anytime you get oil in your compressed air, it is a sign your compressor needs professional repair and probably a rebuild job.
Clean the filter or replace the element on the prescribed schedule – even more frequently if your compressor is in the same room as your cabinet. Take care of your compressor because it’s expensive if you don’t.
