Comparison of clean air solutions

Different customer requirements demand different cleanliness solutions. The most important solutions in cleanroom technology are therefore described here.

Conventional Cleanroom

Nowadays, conventional cleanrooms are generally available in a wide range of cleanliness classes. Conventional cleanrooms are used in particular in the pharmaceutical and semiconductor industries, as very tight climate tolerances are essential for the production of products in addition to the absence of particles. The costs for this type of cleanroom are therefore correspondingly high. 

However, these high-quality cleanrooms are still used in production areas where climatic conditions do not play a significant role. Even if climatic conditions are no longer the main cost factor here, the products and corresponding production processes have to be analysed precisely in order to avoid excessive production costs. It is particularly important to identify those parts of the production process where critical or less critical processes take place in order to be able to adapt the production environment to these processes.

Modular Cleanroom System

For small and medium-sized companies that produce sensitive products under cleanroom conditions, the modular cleanroom system is particularly suitable as a cleanroom solution. In the particular case of a special technical solution, the system consists of an aluminium profile system with flexibly configurable surface elements and can therefore be tailored to the customer's individual requirements for planning and installation.

In addition, the process equipment can be installed in different ways. For example, it can be completely installed in the cleanroom or fitted as a so-called pressurised plug-in variant. The final variant only allows material input and output in the cleanroom, with the rest of the equipment located outside. If required, work surfaces, shelving, wet work stations, separately encapsulated inspection workstations and personnel and material airlocks can also be integrated into the cleanroom system. In addition, the modular system can also be extended if the production area is expanded and thus adapted to the new work area.

Another advantage of the modular cleanliness solution is that no connections are usually made to the building fabric during installation (interesting for rental properties), which means that it can be dismantled at any time and reassembled anywhere else. Furthermore, corresponding interfaces in the system ensure that additional fan-filter modules required for cleanliness can be installed with minimal effort.

Pure working zones

The construction of modular cleanrooms can also be used for smaller modules such as clean workbenches, individual cabins and minienvironments. As individual modules can be easily connected to each other, complex production areas can be gradually created from simple modules, depending on customer requirements. However, once a type of aluminium profile has been used, it should be used consistently so that no interface problems can occur between the modules.

Clean working zones are characterised in particular by the consistent utilisation of the available space at the intended location. The use of clean work zones can also lead to a localised improvement in the cleanliness class of the working environment, as the air circulation additionally filters the room air and can therefore create a zone of higher cleanliness outside the work surfaces.

With the increasing use of small work zones and the connection of individual modules, the transition between clean work zones and modular cleanroom systems is ultimately fluid.
