Actively expands to press against the frame, forming a continuous 360° barrier. This is the core technology enabling true airtight performance and pressure stability in ISO-classified rooms.

Allows the seal to reach set pressure almost instantly and release just as fast, supporting efficient personnel flow without prolonged waiting or pressure loss.

Durable material withstands disinfectants, temperature variation, and long-term aging, ensuring the sealing system remains effective through repeated VHP, alcohol, and detergent cleaning cycles.

Seal activates only after the door is fully closed, preventing air exchange between zones and helping maintain cleanroom cascade pressure design required in GMP facilities.

Immediate system power-off in emergencies enhances operator safety and equipment protection, important for interlocked or automated cleanroom door systems.

Compatible with electromagnetic or electric bolt interlocks, enabling cleanroom zoning control (airlocks, material transfer rooms, decontamination passages).
