Abstract
A pneumatic bypass system for air wash separators is disclosed. The system detects a surge or overflow of sand passing into an air wash separator by means of a pressure probe located in the vicinity of the separator's swinging baffle. When a sand surge is detected, a pressure drop is produced in the probe tube operating a pressure switch and solenoid valve for actuating a pneumatic cylinder and piston assembly for opening the swinging baffle to permit the sand surge to pass the separator lip.
