Apeks ATX40 / DS4

Apeks ATX40 / DS4 twinset - the professional choice for demanding divers.

Recommended for divers who need reliable and efficient equipment, ready to cope with difficult conditions, including diving in cold waters. It consists of a perfectly balanced DS4 first stage and a pneumatically balanced ATX40 second stage, providing comfortable, smooth and quiet breathing, regardless of depth and external conditions.

The DS4 first stage is distinguished by its unique over-balanced diaphragm design. Thanks to this design, the average gas pressure in the hose increases faster than the ambient pressure when descending to depth, significantly improving performance at great depths. In addition, the dry seal system protects the spring chamber from water, which minimizes the risk of freezing, and prevents silt and debris from entering. The DS4 first stage has 1 HP port and 4 MP ports, providing flexibility in equipment configuration. The product is available in DIN and yoke versions for easy customization. What's more, the kit is EAN40 compatible right out of the box, making it a versatile solution for nitrox divers.

The ATX40 second stage is a true innovation in breathing comfort. Its pneumatic balance provides smooth, light breathing, which significantly improves comfort and reduces fatigue on longer dives. The ATX40 features a large purge button that is easy to operate even with thick gloves, which is especially useful in cold waters. The integrated venturi control improves performance at depth while preventing unwanted flow at the surface. Thanks to an extremely efficient exhaust valve and a patented heat exchanger that surrounds the valve mechanism, the ATX40's second stage minimizes the effects of gas cooling during expansion, increasing thermal comfort. In addition, the Comfo-bite™ mouthpiece almost completely eliminates jaw fatigue, providing comfort during long dives.
