Oil Water Separators

Oil Water Separators

Oil water separators, MAS (MPak Axial Flow Separator) Series, are designed to handle either gravity or pumped flow on a single pass or re-circulatory basis.  There are no moving parts to fail or require expensive maintenance as they are equipped with patented MPak® coalescing plates.

  Oil Water Separator

The separator vessel is constructed of carbon steel, with a special corrosion resistant coating both internally and externally.  The MAS consists of a pre-separation chamber with a baffle, a plate inlet chamber directly upstream of the plates, an MPak coalescing plate section, and an outlet underflow/overflow exit chamber.

Each MAS separator is provided with a special cleaning wand to make accumulated solids removal quick and easy.
