3 COP Models

COP 10

COP 30

COP 60

Three COP sizes are available for all makes and models oil-injected rotary screw air compressors up to 600 HP.

All COPs utilize interchangeable elements available in two styles for normal and severe, “high acid” applications.

Elements are stacked 1, 2 or 3 high depending on the model.

2 Element Styles



PE-109 Element

For normal applications, the standard PE-109 element combines both Ion Exchange and Ultra-fine filtration technologies to remove destructive acids and clearance-size solids.





PE-109-RX Element

For severe applications, or compressors with acid gas ingestion problems, high temperatures, or a history of short fluid life, the high capacity PE-109-RX resin-only element replaces the filtration media with 50% more Ion Exchange resin for greater acid removal capacity, and longer element life.
