Cleanroom Cleanroom

Indispensable – Certifi ed top-of-the-range seating for use in cleanrooms It is the sophisticated design coupled with the perfect implementation
of that design that make Bimos cleanroom chairs top of their game.
In order to create “clean” or “sterile” rooms, measures have to be implemented to prevent products
and processes from becoming contaminated. This is a key requirement of the microelectronics sector, Bimos ensures the following in respect of all its cleanroom chairs:
the pharmaceuticals industry, microsystem production, optics, medical engineering and healthcare.
That is why Bimos has worked together with industry and research specialists to develop its innovative
range of cleanroom chairs for use in extreme conditions.

We put our claims regarding the quality of these chairs to the test on a daily basis by subjecting them
to a comprehensive series of tests that prove the low level of particle emissions and the reliability of
the electrostatic discharge measures used. This quality is also borne out by empirical evidence arising
from day-to-day use.

Bimos cleanroom chairs boast astounding properties and meet the requirements of air cleanliness
classification 3 in accordance with DIN EN ISO 14644-1, cleanroom classification 1 as defined by
US Federal Standard 209E and the specifications of the EU GMP guidelines.
