Replaced Air Filter for Ingersoll Rand

In both oil free and oil injected compressors, oil is used for lubrication of the compressor element bearings and drive shaft bearings as well as the gears.

Any dust or dirt ingression will damage the rollers of these bearings and the gear contact surfaces.

Wear of the bearings or damage to the gears will eventually result in rotor contact, this will result in performance loss and reduced compressor element life.

Further damage to the bearing rollers will result in cage-breakage and ultimately complete destruction of the compressor element.

So it's very important to use good performance oil filter to remove the impurities that might be mixed in the oil.
