Surface Buoyancy Air Lift Bag
Enclosed Bottom Parachute Style (TE/DLE)
Canflex Surface Buoyancy Air Lift Bags are heavy-duty inflatable buoyancy units designed for marine salvage, underwater equipment transport, vessel recovery, and emergency flotation. These rugged, high-performance lift bags provide stability and controlled lifting in both shallow and deep water operations.
Reliable Performance for Critical Marine Operations
✔ Versatile Applications – Ideal for raising sunken objects, stabilizing marine structures, towing pipelines, and emergency buoyancy.
✔ Totally Enclosed Design (TE/DLE) – A tear-drop-shaped lift bag with a sealed bottom for maximum control.
✔ Automatic Pressure Relief – Equipped with a spring-loaded venting relief/dump valve that prevents over-pressurization.
✔ Durable Construction – Made from high-strength, coated fabric for long-lasting performance in harsh marine environments.
✔ Convertible Design – Features a 146 mm threaded connector with an airtight cap, allowing the bag to be used as either an enclosed (TE/DLE) or open bottom (OB/DL) lift bag.
