Underwater Air Lift Bag Durable Tear Resistant Material Bright Safety Colors Reliable Performance

Underwater Lift Bags have become indispensable in underwater archaeology, where preserving the integrity of fragile artifacts is as important as retrieving them. Constructed from flexible but highly durable fabrics, these bags can be inflated to provide precise, controlled lift without putting excessive stress on ancient wood, metal, or stone.

The key advantage in archaeological work is the ability to make objects neutrally buoyant, allowing divers to maneuver them without dragging across the seabed. Overpressure valves prevent accidental rupture, and multiple bags can be used together to distribute load evenly. Since many archaeological sites are located far from large ports, the portability of lift bags makes them ideal for remote expeditions.

Note: Other sizes can be customized according to the requirements.

• Advanced Valve Technology
  Dual-action stainless steel valves with corrosion-resistant springs provide both rapid inflation (30 CFM flow rate) and controlled deflation capabilities.
• Integrated Telemetry Systems
  Optional ROV-compatible monitoring with real-time pressure, depth, and load cell data transmission to surface operators.
• Abrasion Resistant Armor
  Kevlar-reinforced base panels with ceramic composite wear pads protect against sharp edges and rough surfaces.
• Cold Water Operation
  Specialized neoprene insulation maintains flexibility in temperatures as low as -20°C (-4°F) without material hardening.

• Shipwreck Salvage
  Recovery of sunken vessels, including boats, yachts, and commercial ships. Used to lift wreck sections, stabilize unstable structures, and assist in cutting operations for removal. Ideal for marine salvage companies and wreck divers.
• Marine Construction
  Supports underwater construction projects such as pipeline installation, bridge pier repairs, and offshore platform maintenance. Provides buoyancy for heavy components during placement and alignment.
• Underwater Archaeology
  Safely lifts delicate artifacts from seabeds without damage. Stabilizes excavation sites and assists in recovering historical shipwrecks while preserving structural integrity.
