Zeagle Atomic AquaticsT3 First Stage Environmentally Sealed Regulator - REG189 DIN
Perhaps by now you know how enthusiastic Atomic Aquatics is about Titanium. What you may not realize is that the Titanium T3 first stage is precision-machined from a solid piece of material requiring 23 individual operations. The 23 operations are performed in a single continuous milling session at the Atomic manufacturing facility. That means each body is carefully and expertly crafted under our watchful eyes to conform to only the most exacting standards.
The Jet Seat Piston. Atomic designed the Jet Seat Piston to eliminate creeping intermediate pressures and minimize maintenance. This unique high-pressure piston seal system is leak-free and self-lubricating.
The Atomic Jet Seat system has no sharp edges that can damage the seat over time, like most competitor's first stages. Instead, Atomic employs a conical seat and blunt-end piston. Our valve seats are precision machined from an extremely strong aerospace specification seat material. This design combination is the most reliable seat system in the industry and enables the seat to go 2-years or 300 dives without service. Diving performance is superior at even low tank pressure.
Features
- Extremely light weight Titanium design
- Large, balanced flow-through piston design for stable intermediate pressures and high performance at low tank pressures
- Exclusive high-pressure piston seal system is self-lubricating for low friction and low maintenance
- Service to 4350 psi (300 Bar) with optional DIN connection
- Environmentally sealed for freeze protection at low temperatures and all around protection from sediment entering the first stage
- Nitrox EAN ready to 40% O2 (M1: up to 80%) from the factory with no internal modifications needed
- CNC machined from solid bar material, the body maintains perfect alignment of the piston and seat to eliminate creeping intermediate pressure problems
- Two high-pressure and five low-pressure ports on swivel cap (T3/B2/ST1/M1)
