You may notice this item listed in your parts manual as part number 23935042. 23935042 is the complete filter assembly including filter head with threads. This does not need to replaced regularly unless it was broken. If your compressor shows 23935042 and you only need the spin-on element, then ordering item #23935059 is correct.
This Ingersoll Rand oil filter element should be changed every 4,000 hours or once every 6 months depending on your run hours. The coolant filter removes debris from the compressor lubricant before being sent back into the compression process or sump. Changing the oil filter element will prolong the life of your compressor by ensuring clean oil is sent to the airend and oil cooler.
