Hollis 500SE DC7 Regulator - www.simplyscuba.com

https://www.simplyscuba.com/collections/regulators-1st-and-2nd-stages The Hollis 500SE DC7 regulator uses servo controlled valve to deliver excellent performance. The 500SE second stage is paired with a new over balanced diaphragm first stage that has been designed to ideal hose routing for tech back and sidemount configurations. The Hollis DC7 first stage uses a stripped down body design to reduce size and weight without affecting integrity or performance. The inline cylinder connection further reduces the overall bulk of the first stage and offers the low and high pressure ports at optimal angles for technical backmount and sidemount configuration. The 500SE second stage uses a newly redesigned pneumatically balanced servo controlled valve for superior performance. 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 inwards and quickly opening the valve further.
