Title:
A GREASE FILTER AND A VENTILATION ARRANGEMENT INCORPORATING SUCH A FILTER
Document Type and Number:
WIPO Patent Application WO/2009/106804
Kind Code:
A3
Abstract:
A grease filter (1, 31) comprises a first frame (2) in which is mounted a first set of baffles (4) and a second frame (3) in which is mounted a second set of baffles (5). The second frame (3) is disposed adjacent the first frame (2) such that the first and second sets of baffles (4, 5) interleave to define therebetween one or more air pathways (10) through the filter (1). A connecting means (11) connects the first and second frames (2, 3) together and is releasable to permit the frames (2, 3) and therefore the two sets of baffles (4, 5) to move apart, in particular to permit the filter (1) to be thoroughly cleaned. Preferably, the frames (2, 3) slide relative to one another between a first position wherein the air pathway or pathways (10) are open and a second position wherein the air pathway or pathways (10) are closed. The grease filter (1, 31) therefore also acts as a fire damper and a ventilation arrangement (20) incorporating such a filter (1) need not also incorporate a fire damper.
