Abstract: A separator having a pressure differential generating system is disclosed. The pressure differential generating system generates a pressure differential with respect to a screen of the separator. Fluid is supplied to the pressure differential generating device to generate the pressure differential across a screen of the separator. The separator can be utilized to separate drill cuttings from drilling fluid to increase an amount of drilling fluid recovered as a result of the pressure differential.

Abstract: A system having a screen having an upper side and a lower side for separating drill cuttings and drilling fluid within a vibratory separator; a tray positioned below the screen for receiving the drilling fluid from the screen; a pressure differential generator coupled to the tray, the pressure differential generator configured to create a pressure differential between the upper side and the lower side through the screen to enhance the flow of drilling fluid through the screen; and a hose assembly coupling the pressure differential generator to a coupler, an inlet of the coupler being arranged perpendicularly between a first outlet coupled to a mist eliminator and a second outlet coupled to a tank.
