FILTER FOR FILTERING GREASY PARTICLES FROM A GASEOUS STREAM, PARTICULARLY POLLUTED KITCHEN AIR, AND EXPELLING DUCT THEREFOR

摘要

A separator for removing oil or fat particles from waste air, more specifically from a catering kitchen, has a system of generally parallel rods normal to the direction of the waste air current. The rods are distributed across the full cross-section of the waste air in the duct, and turbulence is produced in the waste air when it passes the rods so that oil and fat is entrained on the rods.
