Aquatec Twin Cylinder Diving Set Introduction

🙂 What is the AQUATEC Twin Cylinder used for?

➜The AQUATEC Twin Cylinder System is designed for technical and professional divers who require two independent air supplies for safety and extended underwater time. It allows divers to carry redundant air sources, ensuring stability and security during deep or long dives.

➜Beyond scuba diving, the twin tank system is also widely used in underwater engineering, marine research, and rescue operations, where reliable and stable gas supply is critical. It can be applied in commercial diving, underwater welding and cutting, firefighting, flood rescue, and even industrial gas storage or testing systems that demand high pressure stability and durability.

🙂 What are the benefits of using a twin tank instead of a single tank?

➜Twin tanks provide redundancy — if one regulator or cylinder fails, the diver can safely switch to the second system. They also help balance buoyancy, improve stability underwater, and increase total air capacity for longer dives.

🙂 What materials are available (SUS304 / SUS316)?

➜AQUATEC offers twin cylinder bands and rings in SUS304 and SUS316 stainless steel. SUS304 is strong and corrosion-resistant, ideal for most diving environments; SUS316 provides extra protection in saltwater or high-corrosion areas.

🙂Can I use these rings with other brands’ cylinders or manifolds?

➜Yes. AQUATEC twin cylinder bands are designed to fit most standard cylinder diameters and manifolds from international brands. Custom sizes are also available upon request.

🙂 Are these products suitable for saltwater diving?

➜Yes. Both SUS304 and SUS316 stainless steels are corrosion-resistant, making them suitable for saltwater use. For frequent ocean diving, SUS316 is recommended for maximum durability.

🙂Can you offer OEM / Private Label customization?

➜Yes. AQUATEC offers OEM and private label customization, including laser-engraved logos, packaging design, and custom size options for distributors or dive brands.
