All reciprocating compressors have a series of pistons that pump up and down inside their individual cylinders to compress the air to a higher pressure. This rubbing creates friction, which creates heat. In order to conserve the life of the pump, you need some type of protection. Some pumps are “splash” lubricated with oil and some have a teflon-type lining in the cylinder. Oil-less compressors are adequate for lighter use applications and have the advantage of being able to run off-level without worry, however even though they are considered low-maintenance, they tend to wear much quicker due to more heat build-up and repair costs could be extensive. Oil-lubricated compressors have the advantage of keeping the pump running cooler and lasting much longer and are built for the professional who takes pride in ownership and will maintain his equipment. However the key is to make sure the compressor sits level so the “splash”-lubrication is effective and reaches all cylinders. If run off-level, it can score the cylinder and do heavy damage over a short period of time. It is very difficult to claim warranty for the owner in this case.
