Representing the evolution of 50 years of technical diving expertise, the Apeks EVX Tungsten Dive Regulator combines state-of-the-art engineering with rugged, stealthy aesthetics. Built for divers who refuse to compromise on style, substance, or performance, the EVX Tungsten delivers maximum thermal protection and super-smooth breathing in the most extreme, punishing underwater environments on the planet.
Tough PVD Coating, ACD System & Extreme Cold-Water Defense
The forged brass first stage is wrapped in a highly durable Physical Vapor Deposition (PVD) coating, offering superior scratch and corrosion resistance. It features an integrated ACD (Auto Closure Device) that automatically seals the first stage to prevent water and debris ingress when disconnected from the cylinder valve, protecting internal lubrication and keeping the regulator oxygen-safe.
Features and Benefits
- Over-Balanced First Stage: Medium-pressure gas increases at a faster rate than ambient depth, resulting in remarkably effortless inhalation at extreme depths.
- Optimized Port Routing: Equipped with 5 medium-pressure ports and 2 angled high-pressure ports, offering flawless hose routing for single-tank, twinset, or technical configurations.
- Extreme Thermal Protection: Heat exchanging ribs on the first stage body and ribbed diaphragm clamp maximize heat transfer, preventing icing in freezing waters.
- Pneumatically Balanced Second Stage: Features a laminar flow valve, a large breathing effort adjustment knob, and a Venturi lever—all oversized for easy use with thick cold-water gloves.
- Reversible Hose Configuration: The second stage can be configured for either left-handed or right-handed gas supply by an authorized technician.
- Diver Changeable Exhaust (DCE): Allows you to swap between a large exhaust tee (for maximum bubble diversion) and a smaller, streamlined exhaust tee (both sets included).
