Apeks MTX-RC Regulator

Apeks MTX-RC — Uncompromising performance, in all conditions The Apeks MTX-RC is a high-end balanced regulator, designed and manufactured in the UK for those who accept no compromises underwater. Whether you're exploring wrecks in cold water or diving in tropical environments, the MTX-RC ensures a consistent, smooth, and reliable airflow at any depth. First Stage Forged one-piece body in satin chrome-plated brass for maximum robustness and optimal hose routing. Environmental dry kit (standard): the environmental diaphragm prevents water from contacting the main spring, preventing freezing even in extremely cold water. Non-freezing end cap: specific technology to prevent ice formation on the first stage end cap. Heat exchanger: exclusive design that utilizes the body surface to extract heat from the water and increase the temperature of the breathing gas. Swiveling turret with configurable right-to-left orientation: reduces hose tension and allows for customized positioning for maximum comfort. Over-balanced: the over-pressure intermediate pressure system ensures superior performance at depth, with constant flow even with a nearly empty tank. 5 medium-pressure ports (3/8" UNF) and 2 high-pressure ports (7/16" UNF) angled. Removable valve seat: replaceable in case of damage, for simple and convenient maintenance. Dust cap to protect the first stage from water and debris during transport. Trivalent chrome plating: a more environmentally friendly finish than traditional chrome plating, with no compromise on durability. Available in DIN or INT (A-clamp) versions. Second Stage Pneumatically balanced: breathing effort remains constant and low regardless of depth and residual tank pressure. Patented Comfo-Bite™ mouthpiece with an ergonomic palatal bridge to reduce jaw fatigue during prolonged dives. Cover with metallic insert for greater durability and impact resistance. Braided Flexi-hose with double swivel to eliminate tension at both ends and improve comfort during swimming. Ergonomic and intuitive Venturi lever, adjustable even with gloves, to stop airflow and prevent free flow. Inhalation effort adjustment via an oversized system, easily accessible even in cold water. Side opening channels on the diaphragm to prevent free flow even in strong currents. Diver Changeable exhaust (DCE): supplied with 1 set, choose between compact version or optimal bubble deflection. Integrated heat exchanger for freeze resistance in extreme cold water diving. Nitrox compatible: 40% O₂ ready out-of-the-box; can be O₂ cleaned for 100% O₂ use. Recommended operating temperature: 1 – 55°C. Why choose the MTX-RC Imagine descending 40 meters on a wreck in the North Sea: the water is 8°C, the current is strong, and every breath must be certain. The MTX-RC was designed precisely for this. Every detail — from the dry kit to the swiveling turret, from pneumatic balancing to the Venturi lever — is engineered to give you total control and absolute peace of mind, dive after dive.
