Hollis 500SE DC7 DIN diving regulator set

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.
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
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
– DIN/300 bar
