Key Features
Aviation-grade aluminum construction
The cylinder is made from 6061-T6 aviation aluminum, which offers a strong yet lightweight structure. According to the product information, it is designed to handle compressed air at 3000 PSI / 200 Bar and resist saltwater corrosion.
Constant pressure breathing
The regulator is designed to provide steady airflow throughout the dive. This helps support a more natural breathing experience until the tank reaches its reserve level.
Fluorescent pressure gauge
The waterproof, luminous gauge makes it easier to check air levels in lower-visibility conditions. The color-coded display also helps users monitor when it is time to ascend.
Multiple refill options
The Smaco S400 supports several refill methods, including a manual high-pressure hand pump, a refill adapter for larger scuba cylinders, and a compatible high-pressure electric compressor.
Integrated safety valve
The tank head includes an explosion-proof valve that is designed to release pressure automatically if internal air rises beyond safe limits.
Comfortable silicone mouthpiece
The second-stage regulator includes a food-grade silicone mouthpiece intended to improve comfort and reduce jaw fatigue during use.
Typical Uses
The Smaco S400 Mini Scuba Tank 1L is designed for limited-duration underwater activities rather than extended recreational diving. Common use cases include:
