Abstract: Disclosed herein is a device for separating particulate matter from a fluid which includes an inlet conduit which carries the matter and fluid into a separation chamber defined by a substantially spherical dome having separable upper and lower portions and a flattened bottom surface within which is contained a plurality of baffles suitably oriented within the chamber so that the particulate matter and fluid entering within the chamber is caused to go through a tortuous path, the particulate matter experiencing deceleration due to the increased volume within the chamber relative to the conduit, and a liquid reservoir along the bottom edge portion of the chamber for entraining the matter there within, so that fluid can be allowed to leave the chamber while a discreet level of liquid is maintained and controlled within the chamber itself.
