Interlock System

Interlock System is designed for cleanroom doors to control access between different cleanroom areas and help maintain pressure differences, cleanliness, and safety. It prevents two or more doors from opening at the same time, reducing cross-contamination risk and uncontrolled air exchange.

The system is widely used in airlocks, changing rooms, material transfer rooms, pass-through areas, laboratories, pharmaceutical cleanrooms, hospitals, and electronics cleanrooms.
