Hollis DC-7 is a high performance, over-balanced first stage, that provides progressively greater intermediate pressure as depth and gas density increases for superior gas delivery under the most extreme conditions.
The hose routing is ideal for backmount and sidemount configurations -making this first stage extremely versatile.
Environmental sealing protects the system from corrosion, contamination and icing.
This configuration is designed to withstand the rigorous CE standard for coldwater performance and it is Nitrox compatible to 40%.
Features 2 high and 4 low pressure ports.
