Mares AST-1St Stage Dry System DIN Set

MARES AST-1st Stage Dry System DIN Set – Ultimate First Stage Protection

Elevate your diving experience and protect your most critical piece of life-support equipment with the revolutionary MARES AST (Auto-Sealing Technology) First Stage Dry System. Designed as an essential accessory for discerning divers, this innovative DIN set provides unparalleled protection for your regulator´s first stage, ensuring its longevity, reliability, and peak performance on every dive. The AST system is engineered to completely prevent water from entering the first stage, not only during the dive but also, crucially, during post-dive rinsing and transport. This eliminates the primary cause of internal corrosion and contaminant buildup, safeguarding the delicate internal mechanisms from damage.

The genius of the MARES AST lies in its simplicity and effectiveness. The system is automatically activated by gas pressure. When your regulator is not connected to a pressurized cylinder, a physical barrier seals the inlet, creating an airtight shield against water, dust, and humidity. The moment you open your tank valve, the incoming air pressure instantly and effortlessly retracts the seal, allowing for normal, unrestricted operation. This passive, fail-safe design means there are no extra steps for the diver to remember; the protection is always active when you need it most.

By keeping the internal components pristine and dry, the AST system significantly enhances safety and performance, especially in challenging environments. It is an indispensable upgrade for cold-water diving, as it helps prevent moisture from entering and freezing, a common cause of free-flow incidents. Furthermore, because it maintains a clean, dry interior, it is perfectly suited for use with gas mixes containing a higher percentage of oxygen (Enriched Air Nitrox), where internal cleanliness is paramount. This makes the MARES AST a smart investment for technical divers, dive centers, and any recreational diver who wants to ensure their regulator is always in optimal condition, reducing service costs and extending its operational life.
