Construction of a cleanroom.
We accompanied the construction of a cleanroom system with time lapse and drone. In 2.5 minutes, you can see how a cleanroom system measuring over 500 m² is delivered in individual elements and assembled, including air conditioning. In this example, the cleanroom was planned with 16-meter-long trusses to create a self-supporting surface over the entire length.

FAQ
Cleanrooms
What is a cleanroom?
Put simply, a cleanroom is a closed room into which almost dust-free and germ-free air is admitted via a filter system. In a cleanroom, clean air displaces airborne particles, keeps them away from objects with targeted air currents and guides them to the outside. The number of particles per cubic meter of air determines the quality of the cleanroom. The definition of a cleanroom is therefore about the particle concentration of the ambient air, which must be reduced to a low, non-critical level. The controlled elimination of the damaging influence of particles and microorganisms ensures significantly higher quality and safety. Many processes can only be carried out under cleanroom conditions.
There are basically three goals that you want to achieve with a cleanroom:
1. product protection
- Ensuring the quality and function of sensitive products
- Protection against contamination by germs and microorganisms
2. personal protection
- Protection of employees in the event of toxic substances escaping
- Protecting employees from germs and microorganisms
3. environmental protection (cleanrooms with negative pressure)
- Hazardous / toxic substances do not get out
- Dust development remains in a closed room
In many cases, individual protection targets can be met with simple measures. A smaller enclosure, an extraction system, etc. However, as soon as a combination of objectives becomes necessary, the whole thing starts to become more complex. A very striking example is the production of cytostatics. Drugs that are needed for cancer therapy. Here, all three objectives have to be met at once. The product must be manufactured in sterile conditions and people and the environment must be protected from the substances. In addition to a safety cabinet, this also requires a high-quality and safe cleanroom laboratory or sterile laboratory.
What is a cleanroom system?
The term cleanroom system describes the composition of various components for keeping a specific environment clean. Similar to a work process, each component fulfills a specific task so that absolute cleanliness is guaranteed at all times. A cleanroom system includes, for example
- Monitoring elements: These show how many particles there are per m³ of air in the cleanroom and warn you in good time as soon as a certain limit is exceeded. Our precise measuring devices ensure absolute cleanliness at all times.
- Filter systems: They transport “dirty air” outside, while the clean air remains in the cleanroom.
- Cleanroom plenum: This cleanroom ceiling connects different components of the cleanroom system and, above all, ensures smooth return air flow. They transport impure air out of the building.
- Doors, windows, airlocks: our high-quality equipment ensures problem-free working in the cleanroom and consistently high cleanroom air quality.
- Cleanroom furniture: The cleanroom furniture supports efficient work within the cleanroom.
How much cleanroom is needed?
Every square meter of cleanroom is not only expensive to set up, but also to run. Specifying a larger area or a higher cleanroom class ultimately means more filter systems, more “air” and more costs.
The first questions we ask our customers are therefore usually:
- Are you sure you need this cleanroom class?
- Are you sure you need this size of cleanroom?
- Are you sure that you need air conditioning, especially humidity control?
Quite apart from the investment, energy costs play a significant role in question 3. Only when we understand the process can we help the customer to avoid incurring unnecessary costs for cleanroom technology and to avoid “shooting guns at sparrows”. The goal is maximum customer benefit, not maximum turnover.
It does not always have to be a permanently installed cleanroom, but an enclosure or a cleanroom tent is often completely sufficient for manual activities – for example in combination with a table-top device (laminar flow bench). For clean production, a CNC Cleanroom or a combination with laminar flow benches may even be sufficient. This can also achieve the cleanliness class of the controlled environment very well in parts without having to build an entire cleanroom. For mechanical processes, machines can also be installed and encapsulated outside the cleanroom. This involves working with wall openings or conveyor belts into the cleanroom. There are many ways to reduce costs here without compromising on safety.
So how much cleanroom is needed? – As much as necessary and as little as possible.
What does a cleanroom cost?
This is the one question that our sales staff are asked very frequently and often right at the start of a project inquiry.
To be honest, we can’t really answer the price of a cleanroom concretely in a first phone call. And not because we don’t stand behind our prices or want to hide anything. Quite the opposite. It’s simply because we need to receive a whole range of information before we can offer solutions for cleanroom production – often at different prices. When asked about the cost of a cleanroom, a serious salesperson must always reply with “That depends”.
That’s why we have a whole series of counter-questions:
- Which cleanroom class is required?
- How big and how high should the room be?
- Can the ceiling be suspended or should it be self-supporting?
- Is air conditioning required?
- What heat loads are generated?
- Are there GMP specifications?
- How many people will be working in the cleanroom?
These are just some of the parameters that go into a calculation. After all, a cleanroom is not an off-the-shelf product. It must be precisely tailored to the cleanliness requirements and the needs of production. Only then can we decide together with our customers whether, metaphorically speaking, a Porsche is necessary or whether a Polo will suffice.
But to satisfy your curiosity for a moment:
A cleanroom costs between 1,000 and 5,000 euros per square meter.
What does a cleanroom classification mean?
For a cleanroom classification, air samples are taken at various points in the room using a particle counter and the number of particles found is measured. These measurements are used to classify the cleanliness of the room. The classification into cleanroom classes describes the exposure of the room atmosphere to particles of different sizes per room volume. The cleanroom standard is qualified according to a cleanroom class table.
What does the cleanroom classification mean?
- Cleanrooms are differentiated according to their classification. In ISO cleanrooms, the main focus is on the removal of airborne particles, which must not be deposited on sensitive products. In GMP cleanrooms, microbiological contamination by germs and spores must also be prevented.
- The cleanroom classifications in accordance with
ISO standard 14644-1 orGMP guideline Annex 1 determine the overall design of the cleanroom. The more sensitive the processes, the stricter the requirements for cleanroom cleanliness. The cleanroom classes range from ISO 1- ISO 9 and from GMP A- D, with the lower numbers indicating higher particle removal standards.
Depending on the cleanroom class, the air in the cleanroom must be completely replaced at different intervals. This is achieved by laminar air currents that guide clean air into the Cleanroom and force airborne particles out of the Cleanroom.
Which industries are the cleanrooms suitable for according to their classification?
The classification for which industry a cleanroom class is suitable differs depending on the process and requirements. Therefore, the required cleanroom class is determined individually for each cleanroom so that the requirements for the subsequent process are met exactly. Typical areas of application for each cleanroom class are
- Cleanroom class ISO 8 for the automotive industry
- ISO 7 cleanroom class for medical technology
- Cleanroom class ISO 6 for the optical industry
- Cleanroom class ISO 5 for electronics and semiconductor technology
But here too, it always depends on the specific process and the purity requirements of the end product. It is not possible to make a general classification for each industry!
