Q1:How does a Laminar Flow Pass Box work?
A:The built-in fan draws air through the HEPA filter to create vertical/horizontal laminar flow, maintaining positive pressure
inside the box to block external contaminants. UV lamps may be added for sterilization.
Q2:Does a Laminar Flow Pass Box require regular maintenance?
A:Yes. Routine tasks include replacing HEPA filters, cleaning interior surfaces, checking UV lamp efficiency, and monitoring airflow velocity and pressure differentials to meet cleanliness standards.
Q3:What’s the difference between a Laminar Flow Pass Box and a regular pass box?
A:Regular pass boxes only provide physical isolation, while laminar flow models actively control contamination via HEPA-filtered airflow, suitable for higher cleanliness requirements.
Q4:What should be considered during installation?
A:Avoid areas with turbulent airflow or high foot traffic. Ensure sufficient maintenance space around the unit and integrate it with the cleanroom HVAC system to maintain pressure balance.
