All coalescing oil separators use a borosilicate glass filter element, which is designed to remove small oil particles and system contaminants. Therefore, it is important to monitor pressure drop for new installations. Once the pressure differential exceeds 15 psig, it is recommended to replace the filter.

The filter is removable through the top flange assembly. The flange/cover plate arrangement is easy to remove, eliminating the need for additional clearance during installation.
