Cyclone fluid cleaner e.g. for air intakes of internal combustion engine, has reduced pressure loss achieved by air-foil pressure recovery guide in clean air outlet

摘要

A separator for removal of particulates from a fluid stream comprises a housing with inlet and outlet sections, a separator region, and a central hub to which are attached curved air foils shaped to catch the spiral clean flow from the cyclone separating region, to decelerate and direct it into a laminar flow pattern. Independent claims are included for gas cleaning.
