1. 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.

Abstract
The present invention relates to an air-cleaning device for air cleaning in sensitive environments such as operating rooms, drug manufacture, microchip production (processing industry) and similar areas. More specifically, the present invention relates to an air-cleaning device that allows for precise distribution and flow rate within sensitive environments by utilizing a combination of adjustable air ducts, filters, and air distribution which is mobile and changeable.

2. A movable 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,
an adjustably arranged air duct, the adjustably arranged air duct transporting air from said clean-air assembly to the clean-air assembly arranged exhaust-air distributing unit; -
at least one filter is further arranged in the air-cleaning device for air cleaning;
a screen arranged in said exhaust-air distributing unit for clean-air distribution and positioned substantially vertically to provide a substantially horizontal laminar/low-turbulent airflow; and
an angled distribution plate provided adjacent to said screen and controls the velocity of the clean air through the screen so that the clean air flows at at least two different velocities, each different velocity being generated at one of two separate locations on the screen, 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. - View Dependent Claims (3, 4, 5, 6, 7, 9)
