APEKS DS4 1st STAGE DIN REGULATOR 200/300 BAR

First Stage Features

Unique over‑balanced diaphragm design This advanced, over‑balanced diaphragm system increases medium‑pressure gas delivery at a rate faster than ambient pressure as the diver descends. The result is consistently high performance and effortless breathing at depth.

Optimised port layout The first stage includes 1 HP port and 4 MP ports, each precisely angled to ensure clean, efficient hose routing for any configuration.

Environmental dry system A fully sealed dry chamber prevents water from entering the main spring area, eliminating ice buildup in cold conditions and keeping silt, sand, and contaminants out for long‑term reliability.
