How to Replace the Air Filter Element on a Rolair Compressor

Air compressors are similar in many ways to small engines. Both have a piston, piston rings, a cylinder, and valves. Just as a clean air filter is important to protect your lawn mower's engine, you must also maintain your air compressor's air filter to ensure a long pump life. The air filter removes dust, pain, or whatever else might be floating in the air, before it can enter the cylinder and cause damage.
