Hollis DC7 First Stage Only

The Hollis DC7 First Stage has been specifically designed to persist the demanding CE standard for cold-water performance. It is a high-performance over-balanced first stage design. The environmental seal additionally protects the first stage from freezing/icing. It also prevents contaminants from entering and internal corrosion.

The DC7 first stage provides progressively greater intermediate pressure as gas and depth density increases. Thus, the first stage is made to endure extreme dive conditions.

The DIN first stage offers you 2 HP and 4 LP ports. This way you can configure the hose arrangement to your personal preferences. Furthermore, the fixed hose routing is an ideal setup for backmount or sidemount dive systems.

Features:

• High performance over-balanced first stage
• 2 HP and 4 LP ports
• Nitrox compatible to 40%
• DIN or Yoke/300 bar
