SMACO S400 PLUS 1L MINI SCUBA TANK

The Professional Upgrade for Compact Exploration

The Smaco S400 Plus is the enhanced version of the world-renowned S400 series, offering a 1-liter capacity with significant upgrades to airflow and ergonomic handling. While it maintains the compact footprint of the original, the “Plus” edition is designed for those who demand a smoother breathing experience and higher durability. Providing approximately 15 to 20 minutes of underwater air (depending on depth), it is the premier choice for quick reef dives, professional boat hull inspections, and high-performance emergency backup. The S400 Plus combines ultra-portable dimensions with the advanced regulator technology found in Smaco’s larger professional models.


Key Features

  • Enhanced S700-Style Regulator: The S400 Plus features an upgraded second-stage regulator with improved internal geometry. This results in significantly lower breathing resistance compared to standard models, providing a more “natural” air delivery even as tank pressure decreases.

  • Premium Aviation Aluminum: Forged from 6061-T6 Aviation-Grade Aluminum, the cylinder is remarkably lightweight yet capable of safely containing 3000 PSI (200 Bar). The exterior is treated with a specialized anti-corrosion coating to withstand harsh saltwater environments.

  • Real-Time Luminous Monitoring: Equipped with an integrated, waterproof pressure gauge that glows in the dark. This allows for effortless monitoring of your remaining air supply during evening dives or in low-visibility underwater environments.

  • 3-Layer Air Filtration: The high-pressure intake includes a sophisticated multi-layer filter that removes oil, moisture, and fine particulates, ensuring every breath you take is clean, dry, and safe.

  • Universal Refill Options: The S400 Plus offers total flexibility. It can be refilled using the Smaco High-Pressure Hand Pump, an electric high-pressure compressor, or via a standard large scuba tank using the Smaco G5/8 Refill Adapter.

  • Ergonomic Mouthpiece: Fitted with a food-grade, hypoallergenic silicone mouthpiece designed to prevent jaw fatigue, making it comfortable for full-duration dives.

  • Safety Explosion-Proof Valve: An integrated safety disk provides peace of mind by automatically venting air if internal pressure exceeds safe operating limits due to extreme heat or overfilling.
