Outlet port baffle for exhaust air

Abstract From the Canadian patent

An outlet port baffle for an air or gas exhaust port comprises a cylindrical entrance section a, conical intermediate section terminating in an end wall. The conical intermediate section has two rows of apertures extending over an arcuate segment of that section and has radially projecting, circumferential ridges which are between and also define the apertures. Fluid enters the cylindrical section and flows to the conical section where it is redirected in a direction normal to its original flow and through the apertures. The outlet port baffle may be utilized to redirect the air exhaust from a vacuum cleaner, for example.
