ISO 3-4 (Class 1-10)

Most Critical Level Cleanroom Requirements


Nanotek is the classification for products used in environments that need to meet the highest level of cleanroom compliance.

Nanotek products meet ISO standards 3-4, and the federal standard classification 1-10 and are engineered to keep your cleanroom processes operating at the “consistent” state you require. 

These products are used in front-end semiconductor fabs, aseptic operations, LED, biotech, nanotechnologies, and other emerging critical applications.
