Abstract:
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:arranging a screen at the exhaust-air distributing unit; positioning said screen substantially vertically to provide a substantially horizontal laminar/low-turbulent airflow; controlling the velocity of the clean air through the screen, by an angled distribution plate located adjacent to the screen, so that the clean air flows at at least two different velocities which are generated at one of two separate locations at the screen; and arranging the air-cleaning device as a unit mobile in a room, whereby said exhaust-air distributing unit can be moved and directed in such way that said laminar/low-turbulent airflow is distributed where it is desired in the room.
