Cleanrooms are dynamic systems. People and goods are constantly in motion. Installations, production lines and machines are periodically adjusted to the production of different products. According to the relevan standard ISO 14644-3 Annex B7 the operators of cleanrooms are obliged to give periodically evidence of the actual air flow situation by an air Flow
○ Sistema’s ultrasonic water fog (aerosol) generators of the AFM-NEO Series do offer an unmatched potential for zero contamination air flow visualisation and tracking studies in cleanrooms according to ISO 14644-3 Annex B7. All versions of the AFM-NEO Series are portable, are operated with non-contaminating media (DI water) atomized into micro sized droplets.
○ FOG OUTPUT CHARACTERISTICS
