When furnishing your cleanrooms, it is important to remember that commercially available furniture is not sufficient due to inadequate hygiene properties and particle emission. Even furniture that complies with food industry standards does not meet the requirements of higher cleanroom classes. Below you will find assistance to help you select suitable furniture.
By definition, a cleanroom is a room in which the concentration of airborne particles or germs is kept very low. The cleanroom is constructed in such a way that the number of particles that are introduced into the room or that are created there is as low as possible. Cleanroom technology consistently ensures stable, constant and controllable temperature, humidity and pressure conditions.
Cleanrooms are a "must-have" in many sectors, such as medical technology, healthcare, microelectronics, optics and laser technology.
Important factors are low particle emission, chemical and microbiological resistance and hydrophobic properties. Chemical resistance to common cleaning agents and disinfectants is an important differentiator from furniture for use outside the cleanroom. There are certificates for HPL and stainless steel that confirm that they are permanently resistant to standard cleaning agents and disinfectants. Furniture made of chipboard up to RR class ISO 7 is permissible, although not ideal, because any minor damage can lead to the release of particles. Repeated contact with cleaning agents also leads to a change in the surface (it becomes rough and therefore no longer suitable for cleanrooms). We therefore recommend the use of stainless steel or HPL throughout for cleanroom-compatible furniture from class 8 or D.
Stainless steel:
(Oberflächenrauheit < 0,8μm) ist hier state of the art. In höheren Reinraumklassen sollte die Edelstahloberfläche elektropoliert sein, um Partikeln und Keimen eine geringe Angriffsfläche zu bieten. Der Vorteil von Edelstahl ist seine Langlebigkeit, er ist leicht zu reinigen, und Sie können aus verschiedenen Legierungen, entsprechend den Anforderungen, auswählen (z. B. erfordert VE-Wasser mindestens V4A Materialqualität für den dauerhaften Einsatz). Ein weiterer Vorteil ist sein geringeres Ausgasverhalten. Natürlich müssen auch alle anderen Bestandteile des Reinraummöbels (Dichtungen, Funktionselemente) diesen Anforderungen entsprechen.
HPL - High Pressure Laminate:
Due to its functionality, this material meets the highest requirements in cleanroom applications such as microelectronics, pharmaceuticals and life science.
HPL has the following properties:
Their cleanroom-compatible surface should have no gaps or dead spaces, be easy to clean and have no indentations. The requirements generally known under the umbrella term "hygienic design" can be used as a selection criterion here. Hygienic design refers to the design of parts, components and production systems to make them suitable for cleaning.
comprei, the expert for contamination control in cleanrooms, only works with reputable manufacturers who have complete documentation of the materials used and are able to provide the required quality for your cleanroom. We will be happy to advise you on the selection and planning of your cleanroom in order to ensure its economical and safe operation.
Particle containment mats (also known as cleanroom adhesive mats / dust control mats) are a crucial element in maintaining cleanliness in sensitive working environments. But why should particle containment mats be used?
In cleanrooms and other controlled environments, minimizing particles is of paramount importance. Particles can not only affect the quality of your products, but can also disrupt the production process and lead to costly downtime. Particle containment mats provide an effective solution to reduce the ingress of dirt and contaminants by removing particles as they enter the cleanroom. This helps to maintain the cleanroom class and increases overall production efficiency.

Particle retention mats (also known as cleanroom adhesive mats) from comprei - cleanliness that lasts.
Innovative solutions for retaining dirt and particles - efficient, sustainable, customizable.
Brief introduction:
A particle retention mat (also known as a cleanroom adhesive mat for cleanroom airlocks) is a special mat for removing and retaining fine to coarse dirt particles from shoes or wheels in front of sensitive areas. It is used in particular in industries such as pharmaceuticals, semiconductor technology, cleanrooms, laboratories and food production.
Contamination control mats are made from a patented polymer composition that is durable and adhesive by nature. This mat has a proven ability to attract, bind and retain up to 99.9% of contaminants transferred from shoes and wheels and up to 75% of airborne particles. In addition to these special performance features, the system is easy to clean and has a long service life (more than 5 years with good care). This makes the system a cost-effective solution for contamination control in cleanrooms.
