clean room

A cleanroom is a particularly clean environment, such as is required for scientific research or for the manufacture of sensitive products in the fields of medical technology, optics or semiconductor production. A cleanroom is measured by the contamination caused by foreign particles per room volume. There are several gradations depending on the number of particles.

Machines and utensils that are used in such an environment must therefore meet certain requirements. To this end, they are classified into nine different classes based on their effect on the particle concentration in the air. These are standardized by the ISO (International Organization for Standardization).

Classified machines are characterized by their low tribological particle release (abrasion), low electrostatic behaviour and hygienic design. Both the choice of material and the technical mode of operation have an effect on which and how many particles are released. Smooth surfaces without cracks and gaps reduce the formation of contamination sources.

The devices are classified according to their effect on the particle concentration in the air in accordance with the ISO 14644 standard. They are assigned to one of the cleanroom classes ISO1 to 9, with each class describing a different maximum level of particles per cubic meter, with 1 being the best class to achieve.

Machines with a cleanliness level of ISO9 (max. 293,000 particles ≥ 5.0 µm (micrometers)) to ISO6 (max. 293 ≥ 5.0 µm) are widely used in the food industry. The regulations in the semiconductor and chip industry are even stricter. To prevent electrostatic interference and contamination, cleanroom-certified devices used there comply with the even finer classifications ISO5 (max. 29 ≥ 5.0 µm) to ISO1 (max. 2 ≥ 0.2 µm).

Our stainless steel motor has the ISO1 cleanroom classification. Our stainless steel agitators can be ordered as an option for cleanroom use.
