What is room air made of?
Room air mainly consists of nitrogen, oxygen and argon, an inert gas. Then there are numerous trace gases, aerosols, water vapour, dust and biological particles.
-
How are room air and clean room related?
Airborne particles in particular play an important role in clean rooms. It's best not to get there in the first place. The number of particles/m³ determines the cleanroom classification according to the ISO standard 14644-1 or according to the GMP guidelines Annex 1. The classes range from 1 to 9 and from GMP A to D. The range of industries that cleanrooms for certain is correspondingly large manufacturing steps or entire production lines.
-
What is the definition of a clean room?
"A room with a defined concentration of airborne particles, which is constructed and used in such a way that the number of particles brought into the room or created and deposited in the room is as small as possible, and in which other cleanliness-relevant parameters such as temperature, humidity and pressure are regulated as required .” (VDI Guideline 2083-1) A clean room can contain a complete production line or be a single facility.
-
Who needs a clean room?
Certain industries and areas require clean rooms for production, finishing, processing and packaging. This includes the chemical and pharmaceutical industry, semiconductor manufacturing, the automotive industry and food manufacturers. Depending on the requirements of the clean room, the air must be completely exchanged at certain intervals in order not to exceed the number of particles in the room.

How is a clean room created by the NETZER GROUP?
Rough planning → detailed planning → neutral tender among the industry leaders → best bidder determination → award → project and implementation support → inspection of the installed systems → commissioning → acceptance → support during operation → evaluation
-
Which measurements and examinations are required for a clean room qualification?
Particle measurements / microbiological surface examinations / active and passive determination of airborne germ counts / volumetric flow measurement to determine the air exchange rate / recovery measurement / leak test on the built-in filter system / pressure difference measurements / temperature, humidity, light intensity and sound pressure measurement
