FAQ
1. How are the airbags inflated and deflated?
Using standard air compressors or scuba tanks via quick-connect inflation valves and deflation outlets.
2. Do you offer custom designs?
Yes, we can customize size, lifting capacity, fittings, and accessories to meet your project requirements.
3. How should the airbags be stored?
Store in a dry, shaded area away from direct sunlight and chemicals. They should be fully deflated, cleaned, and rolled.
4. Can the airbags be used in rough seas?
Yes, but care must be taken during inflation and lifting to ensure control and stability, especially in dynamic conditions.
