Qualia’s pneumatic seal doors are crafted to reach flush thresholds, thus eliminating the inherent tripping hazards found in mechanical seal doors. They deliver superior air tightness in applications involving high traffic flow, wheeled equipment, or large animals. Furthermore, these seals facilitate superior sealing during cleanroom facilities and laboratory purification and fumigation processes. The framework can be used for sealing cast concrete walls, column partition walls, stainless steel panel and block engineering walls. 

Additionally, its unique design allows a single individual to replace the seal strip, negating the need for multi-person door dismantling.

The working principle: When the door is open, the inflatable seal strip deflates and retracts into the groove. When the door is closed, the inflatable seal strip inflates and expands, creating a tight seal between the door leaf and the door frame, while the door gets securely locked.
