Product Description

This Self Cleaning Dynamic Pass Box is designed with the option of two electronic or mechanical interlocking devices. These interlocking systems synchronize the opening and closing of double doors, effectively preventing cross-contamination of the air. Additionally, ultraviolet germicidal lamps are integrated for sterilization, providing an extra layer of defense against bacterial intrusion.




The working principles of the mechanical and electronic interlocking devices are as follows:

Mechanical Interlocking Device:

The mechanical interlocking is implemented internally within the pass box. When one door is opened, a mechanism ensures that the other door remains locked and cannot be opened simultaneously. The closed position of the first door is a prerequisite for unlocking and opening the second door. This physical linkage mechanism prevents both doors from being open at the same time, effectively minimizing the risk of cross-contamination.


Electronic Interlocking Device:

Internally, the electronic interlocking device utilizes integrated circuits, electromagnetic locks, control panels, and indicator lights. When one door is opened, the indicator light on the other door does not illuminate, signaling that it cannot be opened. Simultaneously, an electromagnetic lock engages to physically prevent the opening of the second door. Upon closing the first door, the electromagnetic lock on the second door is activated, and its indicator light illuminates, indicating that the second door is now accessible. This electronic control system ensures a secure and sequential operation of the pass box doors, maintaining the integrity of the controlled environment.

Application areas

Self Cleaning Dynamic Pass Boxes are widely used in microtechnology, biological laboratories, pharmaceutical factories, hospitals, food processing industries, LCDs, electronics factories and other places that require air purification.
