This Powerex OEM air filter element should be changed every 2,500 hours. It is recommended to change the filter more often If your compressor is located in a dirty environment with lots of dust. Changing the air filter will prolong the life of your compressor by protecting the tip seals on the inside of the compressor. Proactively changing the air filter will also increase your energy efficiency by not restricting the inlet airflow going into the air compressor.
This item is used on the SLAE05E, SLAE05EHP and the SLAE03EB bare scroll compressor pumps. Note that many of their scroll systems will have multiple bare pumps in the compressor cabinet, so you may need to purchase multiple filter elements at the same time.
