Description

Versatile Underwater Lifting Solutions‌
DOOWIN underwater air lift bags are highly versatile tools designed to safely support and lift loads at various depths. With a single-point attachment system, they are perfect for lightening underwater structures like pipes or salvaging vessels from the seabed. These durable bags withstand harsh environments, and larger models can even be surface-towed at speeds up to 1.5 knots in moderate sea conditions.

Engineered for maximum lift with minimal height, DOOWIN underwater air lif tbags feature a wide hem design for rapid emergency inversion—enhancing diver safety. The bags automatically vent excess air during ascent, ensuring stable operation regardless of load orientation. Their streamlined rigging reduces shipping weight without compromising strength or safety, making them ideal for challenging subsea conditions like poor visibility and strong currents.
