Element change on E2M175 and E2M275 pumps
Change the element when oil mist starts to show at the filter outlet, when the pump's exhaust pressure rises, or at least once a year. On most duties it is worth checking every six months.
Clean exhaust in labs and plant rooms
A working mist filter stops the oil haze and smell that an oil sealed pump gives off at its exhaust, which matters in labs, clean rooms and closed plant rooms.
Keeping oil in the pump
Oil caught by the element drains back through the oil return, so the pump loses less oil between top ups.
No. It is an aftermarket mist filter element made to replace the Edwards A22304021. It is not made by or affiliated with Edwards, and the part number is used only to show what it replaces.
It replaces the element in the Edwards MF300 outlet mist filter, as fitted to the E1M175, E2M175, E1M275 and E2M275 pumps. Check the part number on the old element or in your pump manual before ordering.
