The Facet 3 AGB Series vertical housing permits easy access for inspection or change out of media. The baffle plates at the inlet remove a large amount of solid particulate matter and entrained liquids which are collected in the quiescent sump. The large sump area also provides for slug control. Use of the impingement baffle permits coalescer cartridges to function more efficiently in the removal of microscopic solids and the fine liquid entrainment.
