Air Bubble Technique

An air-bubble installation offers effective and long-term protection from floating debris. Even at varying water levels, it ensures the proper functioning of a lock.

Entire harbour entries can be blocked by an air-bubble installation without shipping traffic being disrupted.

Our air-bubble system consists of a thick-walled polyethylene pipe that is anchored to the bottom of the particular body of water. Compressors provide the hose system with compressed air. The air escapes through special built-in nozzles, and the stream that emerges is divided into countless tiny bubbles that float to the water’s surface. There they create a horizontal current that flows in two directions. Floating debris cannot pass the barrier created by this current.
