The system integrated into the design of our 3.0 Inflatable Seal Doors eliminates the external anti-vandalism tube, allowing air to reach the frame through the hinge. In this way, the perforations in the frame are reduced, obtaining a greater tightness, in addition to reducing the number of necessary pneumatic connection elements.
The hinges are made of aluminum or stainless steel. Its design and robustness allow easy maintenance and more effective cleaning, as well as greater durability.
