Claims22
An air filter comprising a duct forming a passageway extending between an inlet and an outlet of the air filter, the duct comprising bristles extending from a wall of the duct across at least a portion of the passageway so as to remove entrained particles from air passing through the duct, wherein the duct comprises an inlet passageway in series with an outlet passageway, and wherein the outlet passageway has a smaller bore than the inlet passageway.
An equipment room comprising an interior and an air filter including a duct forming a passageway extending between an inlet and an outlet of the air filter, the duct comprising an inlet passageway in series with an outlet passageway, the inlet passageway being lined with bristles extending from a wall of the duct across the inlet passageway over at least a portion of a length thereof, wherein the bristles are orientated transverse to the general direction of air flow through the inlet passageway, wherein the inlet passageway is arranged to allow air to be drawn into the equipment room vertically upwards through the inlet passageway from an exterior environment and towards the interior of the room, and wherein the bristles are configured to remove entrained particles from air passing through the duct and allow the removed entrained particles to drop out of the inlet passageway through the action of gravity.
