Applications :- 

Pass boxes are widely used in microbiology laboratories in food, pharmaceutical and chemical industries. In a Clean Room facility where a sterile environment is paramount, equal importance must be given to ensuring the movement of materials does not compromise the sanctity of the cleanroom. Hence Pass Boxes are used in cleanrooms to minimize the contamination due to movement of material and personals. Dynamic pass boxes are used to transfer materials from uncontrolled to controlled environment. Dynamic pass box works like an airlock or laminar air flow unit. Clean air enters in the pass box and prevents the entrance of the contamination. The inclusion of a HEPA filter and equipment for complex air handling help keep contaminants at bay and allow the cleanroom to achieve higher clean certification.  Dynamic pass boxes have a re-circulatory air system with a certain percentage of air intake as fresh air to keep it under positive pressure. It has a microprocessor-based controller to manage door interlock, UV light–hour meter, door open delay and other application based requirements.
