HOLLIS 500SE DC7 REGULATOR - YOKE
Regulators & Occys - Hollis
Old School. New Tech. 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.
- 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
- 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
- DIN/300 bar
