Edwards lists the EMF20 filter for RV12, E1M18, E2M12 and E2M18 pumps. Check the filter label as well as the pump model when ordering: an existing installation may have a different exhaust arrangement.
The coalescing media captures fine oil droplets in the exhaust gas. The collected oil drains into the filter housing. Ask about the complete filter assembly if you are fitting exhaust filtration to a pump for the first time.
