Inflatable buoyancy units are enclosed cylindrical shape design. It is known as enclosed air lift bags, marine salvage bags, or salvage pontoon.
Inflatable buoyancy units are mainly used for buoyancy support, marine salvage, and re-floatation operations. Furthermore, we also can use inflatable buoyancy units as buoyancy support pontoons for bridges, floating platforms, dock gates, sunken objects, or military equipment. Inflatable buoyancy units offer an effectual floatation method of reducing the draught of the vessel and lift bag salvage underwater structures. Likewise, these marine salvage bags also are ideal buoyancy modules for cable or pipeline laying and boat lift air bags.
Made of heavy duty PVC coated polyester fabric. Reach 10,000N/5cm.
Relief valves can open automatically to release inside pressure to prevent burst.
Design safety working factor 5:1 at least complying with IMCA D016.
Certificate webbing harness (with 7:1 SF) terminate with end shackles.
The specifications below are for common-size inflatable buoyancy units. In addition, we also make inflatable buoyancy units of other sizes and other lifting capacities upon request.
The standard color is YELLOW. We also make orange color and other customized colors. We also make the customized designe and size.

DOOWIN is committed to providing high quality proof-load testing water weight bags and air lifting bags for our customers worldwide.
Air lift bags exhibit remarkable adaptability, making them perfect for secure load support and elevation regardless of water depth.
Pillow-shaped enclosed flotation bags can float objects in extremely shallow water, utilizing upright or flat, outside or inside of structures.
The extended design combined with a smaller diameter can ensure that it provides a large buoyancy in shallow water.
Mono buoyancy units enable efficient pipeline/surface operations with time-saving single-point connections and wide-angle adaptability.
DOOWIN specializes in manufacturing high-performance underwater air buoyancy bags designed for marine salvage, buoyancy assistance, and emergency rescue operations. Crafted from durable, high-strength materials, our bags are engineered to withstand extreme underwater pressures and harsh environments. Available in multiple sizes and load capacities, they offer versatile solutions for lifting sunken objects, stabilizing submerged structures, or providing critical flotation support during rescue missions.
Thank you for the opportunity to serve you.
