Description
Hollis 500SE DC7 Regulator
Old School. New Tech.
The Hollis 500SE revisits the side exhaust design, with a modern stylish, and re-engineered servo-controlled valve, delivering excellent performance. Together with an over-balanced diaphragm first stage that has been designed for ideal hose routing.
The Hollis 500SE Second Stage utilizes a Servo Controlled Valve to provide precision airflow and unparalleled performance. The servo-controlled valve works as the air starts to flow into the second stage, it creates a vacuum behind the diaphragm, drawing it inward and quickly opening the valve.
The side exhaust configuration means there is no right way up and can be used for both left and right setups. Fitted with an orthodontic mouthpiece which helps to reduce jaw fatigue and improve bite comfort.
The Hollis DC7 First Stage provides for superior gas delivery under the most extreme conditions.
Designed to withstand the Rigorous CE Standard for cold water Performance.
