This was a common filter used on several varients of Atlas Copco's GA5-11 range of compressors. Many oil filters were used in this model range, so we recommend sending us your serial number for confirmation this is the correct filter for your compressor. The oil filter removes particles and debris from the compressor lubricant. Changing the oil filter element will prolong the life of your compressor and ensure clean oil is sent to the airend and oil cooler.
