Our critical environment ultra-clean products are designed to operate in ISO 14644 Class 1 (0.1 µm particles) and meet our in-house standard, Extended ISO Class 1. This in-house standard is based on an extrapolation of ISO 14644-1 to smaller particle sizes but no changes to ISO 14644-1. The basis of the extrapolation employs the formula used to define the existing ISO 14644-1 class limit lines. When extrapolated, the permitted number of particles sized 0.01 micron, and larger is 1200 particles/m3 (or 34 particles/ft3 ).
These ultra-clean ionizers are the perfect solution for those manufacturing or test environments that require the highest control level of airborne contaminants.
