Clean Room Design Layout

A cascading air flow design and positive pressure hvac calibration move the cleanest air at the highest pressure iso 7.

Clean room design layout.

The 4 important air conditioning design considerations for clean room system design are. Read it in detail here. High pressure air in clean areas prevents dirty air from leaking into the cleanroom from adjacent. In medical device cleanrooms a common configuration is an iso 8 gowning room and iso 7 primary production area.

The above suggested air changes per hour are only a design rule of thumb. Supplying airflow in sufficient volume and cleanliness to support the cleanliness rating of the room. The above suggested air changes per hour are only a design rule of thumb. They should be computed by an hvac cleanroom expert as many aspects must be taken into consideration such as the size of the room the number of people in the room the equipment in the room the processes involved the heat gain etc.

Introducing air in a manner to prevent stagnant areas where particles could accumulate. A clean room gmp cleanroom in my mind are a combination of engineering design fabrication finish and operational controls control strategy that are required to convert a normal room to a clean room.
