20t Buoyancy Bags Easy To Deploy Foldable For Storage Quick
Inflation
Description
Designed for heavy-duty marine lifting tasks, our Underwater Air
Lift Bags provide high buoyancy in deep or shallow waters. Built to
withstand tough underwater conditions, these bags support loads
from a few hundred kilograms to several tons. The reinforced
construction, strong lifting belts, and corrosion-resistant valves
ensure safe and stable performance during critical lifting
operations. Whether for ship recovery, large pipeline installation,
or offshore construction, these lift bags deliver dependable
performance and high lifting power in even the most demanding
environments.

Advantages
Custom Load Capacity Options
We produce lift bags ranging from 100kg to 50+ tons, tailored to
specific project requirements.
Advanced Pressure Management
Integrated auto-venting valves prevent overinflation and ensure
safe, controlled ascent.
Rigorous Quality Control
Every bag undergoes pressure testing, load stress tests, and seam
integrity checks before shipment.
Depth Specific Engineering
Our bags are rated for shallow (30m), mid-depth (100m), and
deep-sea (300m+) operations.
FAQ
1. How do I inflate the bag underwater?
Via scuba regulator, surface-supplied air, or low-pressure
compressor.
2. What’s the maximum lift speed?
Recommended ≤10m/min to avoid uncontrolled ascent.
3. How do I attach it to a load?
Use integrated D-rings with slings/chains, ensuring balanced
rigging.
4. Can multiple bags be used together?
Yes, synchronized lifting with evenly distributed bags is common
for heavy loads.
5. How do I deflate the bag?
Open dump valves or invert the bag to release air.
