OSTI ID:7321466
An air precleaner for internal combustion engines having a central conduit for conducting precleaned air to the air intake of the engine is described. A housing is disposed around the central conduit and forms an air intake opening, an arcuate wall spaced radially outwardly from the conduit and substantially concentric therewith for conducting the incoming air stream from the intake opening around the conduit so that any dust in the air stream is collected along the housing wall by centrifugal action, and a dust outlet for discharging dust from the housing at the downstream end of the arcuate wall.
