<p>Device for extraction of greases in aerosol form from an air flow in a ventilation system, which device comprises a number of intermediate plates (16) which define both an increased surface of deposition for the greases, and an extended flow path in the ventilation system, which flow path exhibits an alternating direction of flow and an alternating cross sectional area. According to the invention, each intermediate plate (16) exhibits a turbulence inducing wing (26), along a free edge thereof which forms the highest situated point or line in each intermediate plate in the device, which wing (26) is directly followed in the flow path by an increased cross-sectional area for the air flow.</p> |
