Required air quantity
The cleanroom class mainly depends on the quantity of floating particle filtered air supplied every hour. The cleanroom class also depends on the quality of the room shell and the processes carried out in it.
Low cleanroom classes are generally achieved with a 20 to 30-fold air exchange, higher classes may require a 50 to 100-fold air exchange. The highest classes are then no longer characterised by the air exchange but by the velocity and the direction of the clean air flow (=> low-turbulence displacement flow, laminar flow).
The required air quantity is directly related to the operating costs of a cleanroom, so that it is attempted to keep the air quantity as low as possible. This is achieved if the size and cubage of the cleanroom are minimised and priority is given to a high quality of the cleanroom cabin.
