Apeks EVX Tungsten - the ultimate diving regulator

The Apeks EVX Tungsten represents the evolution of more than 50 years of technical development by Apeks. It combines state-of-the-art regulator technology with a robust design, high durability and extremely smooth breathing. Maximum thermal performance, precise ergonomics and reliability make it the ideal choice for demanding divers who require perfect performance in any environment - including extremely cold water.

First Stage

• PVD-coated brass body with thermal fins for maximum cold dissipation
• Ribbed diaphragm clamp improves heat exchange in cold water
• Unique over-pressure (overbalanced) diaphragm design - provides higher performance with increasing depth
• ACD system prevents water from entering the first stage
• 5 medium pressure (MP) ports for optimal hose routing
• 2 angled high pressure (HP) ports for ideal hose routing and transmitter mounting
• Double hose swivel for greater freedom of movement and comfort

Second stage

• Ergonomic and easy to use venturi lever
• Large breathing resistance adjustment wheel - easy to use even with gloves on
• Laminar flow valve for smooth breathing
• Two-stage progressive purge button
• Resettable for left or right throttle inlet configuration
• Integrated heat exchanger to reduce risk of freezing in cold water
• Diver Changeable Exhaust (DCE) system - small or large exhaust Tpiece
• Comfortable Comfo-bite™ mouthpiece
• Knitted flexible hose with better cold water resistance than traditional rubber hoses
