Surface Buoyancy & Underwater Air Lift Bag – Tetrahedron Style

The “SLE”-Enclosed bottom or “SLD”- Open Bottom lift bags are a Surface & Underwater Lift Bag Tetrahedron Style. These units are equipped with either a positive venting air relief valve or a diver controlled manual dump valve, respectively. The Dump Valve allows air control with a push of a button at the top of the bag and a lanyard at the bottom—vent air from above, beside, or below the lifting bag to achieve desired ascent rate. The Enclosed bottom lift bag style also has a 98 mm threaded connector with an air tight cap.

These lift bags are ideal for smaller lifts in shallow waters due to their low profile. The Tetrahedron Style lift bags are small in size and can be stored easily after use and easily repairable.

  • All seams RF welded.
  • Versatile and stable shape.
  • Single lifting / attachment point.
