Apeks XTX40 / DS4

Apeks XTX40 / DS4 - High-Performance Regulator for Technical Diving

The Apeks XTX40 / DS4 is a high-performance regulator designed for divers who seek reliable breathing ease and durability. Featuring a pneumatically balanced second stage, it offers smooth, easy breathing even at depth. With a dry-sealed first stage and a heat exchanger on the second stage, the XTX40 is also well-suited for cold water diving. Though positioned as a mid-range model, this regulator is rated as high-performance in independent reviews, comparable to premium models.

The XTX40 includes essential features found in the well-regarded XTX50, except for diver-adjustable breathing resistance, making it an affordable yet highly effective choice. Additionally, it is EAN40-compatible straight out of the box, offering flexibility in breathing gas choices.

First Stage DS4:

• Unique over-balanced diaphragm design increases medium gas pressure as depth increases, resulting in excellent performance at depth.
• Dry-sealed environmental system protects the main spring chamber from ice, silt, and contaminants.
• Ports: 1 HP port and 4 MP ports, providing versatile gear configurations.
• DIN-style tank fitting for secure compatibility with various setups.

Second Stage XTX40:

• Pneumatically balanced second stage for smooth breathing.
• Dual-stage purge button for variable air flow control—ideal when filling lift bags or when a precise air stream is needed.
• Large Venturi lever with a soft-grip rubber handle for easy location and operation underwater, minimizing grit and resistance.
• Adjustable breathing effort knob allows the diver to customize their breath control.
• Active antimicrobial protection—materials help combat bacteria, viruses, molds, and fungi.
• Silicone exhaust valve for optimized breathing efficiency.
• Comfo-bite™ mouthpiece virtually eliminates jaw fatigue.
• Built-in heat exchanger disperses the cold generated from gas expansion, while drawing warmth from the surrounding water.
