DC7 First Stage:

• High performance over-balanced first stage provides progressively greater intermediate pressure as depth and gas density increases for superior gas delivery under the most extreme conditions.
• Fixed hose routing ideal for both backmount and sidemount configuration.
• Environmental sealing prevents internal corrosion, contaminants, and icing of the first stage.
• Designed to withstand the rigorous CE standard for coldwater performance.
• Nitrox compatible to 40%
• 2 High Pressure and 4 Low Pressure ports.
• Available YOKE / DIN two kinds of tank connector.

500SE Second Stage:

• Pneumatically balanced servo valve system.
• Patented Orthodontic Mouthpiece for comfort and reduced jaw fatigue.
• Standard with 30" maxflex hose.
• Easily disassembled without the use of tools and underwater if necessary.
• Left or right positioning - no upside down.
• Boltsnap tie point.

Description:

The new 500SE utilizes a servo controlled valve to provide precision airflow and unparalleled performance for both air and trimix divers in a side exhaust configuration. To achieve this, we have perfected the original "lever-servo valve" we designed 35 years ago. Overbalanced diaphragm first stage also provides ideal hose routing for both backmount and sidemount users and optimum performance regardless of depth.
