Abstract
A liquid collection vessel for an air and liquid vacuum system of the type incorporating an air vacuum unit coupled to the vessel for drawing air and liquid therein. The vessel includes a generally cylindrical housing having an upper region. An ingress nozzle is disposed in the upper region of the housing and is adapted for receiving air and liquid there through and into the housing in response to low pressure created by the vacuum unit coupled thereto. The ingress nozzle is further disposed angularly within the housing for discharging air and liquid into the housing in a descending, tangential flow pattern. An air intake manifold is likewise disposed within the housing and coupled to the air vacuum unit for drawing air out of the housing.
