1st Stage DS4

The Apeks DS4 1st Stage

The Apeks DS4 1st stage offers you a reliable and powerful solution for your Apeks regulator. With its diaphragm-controlled technology, it is ideally suited for upgrading your Apeks regulator, such as the Apeks ATX 40 DS4, for cold water configurations.

Optimal First Stage for an Apeks Cold Water Configuration

The DS4 1st stage can be easily combined with an Apeks octopus. This gives you a practical two-regulator configuration, which is ideal for cold water diving. Particularly in situations where you require two independently sealable regulators, the DS4 impresses with its excellent cold water characteristics.

No matter how cold the water is, the Apeks DS4 1st stage remains powerful. It is completely sealed and features a dry chamber that provides optimal protection against contamination. This way, you are perfectly prepared for your dive – even under extreme conditions.

Apeks 1st Stage with Reliable Performance

Thanks to its diaphragm-controlled design, the Apeks DS4 1st stage ensures a constant airflow performance. Regardless of dive depth or cylinder pressure, the breathing resistance remains pleasantly consistent. You can rely on being able to breathe comfortably and effortlessly, even at great depths or with very low cylinder pressure.

Thoughtful Connection Options

The Apeks DS4 1st stage is equipped with a high-pressure connection and four medium pressure ports, which are strategically placed. This provides a comfortable and flexible hose routing, allowing you to focus on what matters most – diving.

The DS4 1st stage comes with a DIN 200/300 bar connection and is available in our online shop as both a standard and an Apeks Nitrox 1st stage.
