Hollis 500SE DC7 Regulator

 

 

 

Old School. New Tech.

 
The Hollis 500SE DC7 Regulator revisits the side exhaust design, with a modern stylish design and re-engineered servo controlled valve to deliver excellent performance. Paired with a over balanced diaphragm first stage that has been designed for ideal hose routing for tech, back and side-mount configurations.
 
The Hollis 500SE Second Stage utilizes a Servo Controlled Valve to provide precision airflow and unparalleled performance for both AIR-and-TRIMIX divers in a side-exhaust configuration. Just the smallest, gentlest inhale starts the servo valve working as air starts to flow into the second stage, it creates a vacuum behind the diaphragm, drawing it inward and quickly opening the valve further.
 
The side exhaust configuration means there is no right way up, it can be used for both left and right set ups without modification. Comes with an orthodontic mouthpiece which helps to reduce jaw fatigue and improve bite comfort.
 
The Hollis DC7 First Stage provides progressively greater Intermediate Pressure as depth and gas density increases for superior gas delivery under the most-extreme conditions.
 
This regulator system is designed to withstand the Rigorous CE Standard for cold water Performance.
