The present invention relates to an air-cleaning device for air cleaning in sensitive environments such as operating rooms, drug manufacture, micro-chip production (processing industry) and similar areas. More specifically, the present invention relates to an air-cleaning device (2) comprising a clean air assembly (4) with an inlet, through which air is sucked in from the ventilated room by means of a fan arranged in the clean-air assembly, the clean-air assembly further comprising an adjustably arranged air duct (6), said air duct transporting the air from the clean-air assembly to an, at the clean-air assembly arranged, exhaust-air distributing unit (8) to which is arranged a screen (10) for clean-air distribution, the screen comprising at least one pressure-fall increasing means (12) providing for leveling out the velocity of the exhaust air and distributing a low-turbulent or laminar airflow, in the air-cleaning device is further arranged at least one filter for air cleaning, the air-cleaning device (2) being a unit (14, 18) arranged to be mobile in the room, whereby the exhaust-air distributing unit can be moved and directed in such way that a laminar/low-turbulent airflow is distributed where desired in the room and not be hindered by personnel or other equipment in the airflow path to a specific area of the room. The present invention is also related to a use of an air-cleaning device and a method of producing an air-cleaning device.
An air-cleaning device for air cleaning in sensitive environments comprising a clean-air assembly with an inlet, through which air is sucked in from a ventilated room by means of a fan arranged in the clean-air assembly, said clean-air assembly further comprising an adjustably arranged air duct, the adjustably arranged air duct transporting air from said clean-air assembly to, an at the clean-air assembly arranged exhaust-air distributing unit whereby in the air-cleaning device at least one filter is further arranged for air cleaning and a screen is arranged in said exhaust-air distributing unit for clean-air distribution positioned substantially vertically to provide a substantially horizontal laminar/low-turbulent airflow, said air-cleaning device being a unit arranged to be mobile in a room, whereby said exhaust-air distributing unit can be moved and directed in such way that a laminar/low-turbulent airflow is distributed where desired in the room.
The air-cleaning device according to any of the preceding claims, wherein said at least one filter is arranged in said exhaust-air distributing unit and comprising pressure-fall increasing means.
A method of arranging air cleaning in sensitive environments, comprising arranging a clean-air assembly in an air-cleaning device and arranging an exhaust-air distributing unit at the clean-air assembly, comprising the steps of:
