Hollis 500 SE DC7 REG DIN

500 SE DC7 REGULATOR

The Hollis 500 SE is a unique high- performance side-breathing regulator that due to its unique servo assisted 2nd stage valve offering unsurpassed air delivery. The 500SE utilises a main valve diaphragm that opens to deliver air out of 7 holes in the valve-housing delivering a higher volume of air compared to a traditional 2nd stage.

Ambidextrous by design, the 500SE so perfect for technical diving, but equally at home being used by recreational divers that want the best in performance and with no exhaust bubbles in front of your eyes, it provides an unobstructed view.

The DC7 1 St stage is an overbalanced Diaphragm design that is also completely environmentally sealed ensuring trouble free operation for 100’s of dives.

The inline design minimizes pressure drop as air is directed straight from the tank valve through the 1st stage valve to the low pressure hoses causing minimal air turbulence and improving 1st stage flow.

The 500SE DC7 is available in both DIN and Yoke configurations and is Nitrox compatible to 40%.
