Edwards Oil Mist Filter Return Drain Back Kit

When fitted, the Edwards EMF Oil Drain Kit returns oil trapped in the oil mist filter to the pump, through the gas ballast port. This reduces oil loss from the pump and minimizes the need to check the pump oil-level and to refill the pump with oil. This is the oil return kit only, EMF oil mist filter and pump sold separately. 

Fits Edwards EMF Oil Mist Filters and the following pumps

Edwards Rotary Vane Pumps RV Series (ALL), SpeediVac 2, E2M0.7, and E2M1.5.
