Product Overview

Old school, new tech, the new 500SE utilizes a servo controlled valve to provide precision airflow and unparalleled performance for both Air-and-Tri-Mix divers in a side exhaust configuration. To achieve this, Hollis Gear has perfected the original "lever-servo valve" they designed 35 years ago. 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. Air flow is increased by allowing it to flow through multiple valve ports rather than a single port.

This pneumatically balanced regulator has a large soft purge cover for easy clearing of the regulator, patented orthodontic mouthpiece for comfort and reduced jaw fatigue. Regulator is easy to disassemble without the use of tools and even underwater if necessary. Regulator can be configured for left-or-right positioning, no upside down. The obvious feature of the side exhaust configuration is that bubbles don't get in a diver's face when they exhale. Recreational divers and especially underwater photographers will appreciate that. Regulator is made from impact resistant Delrin plastics, rubber, stainless steel and chrome plated brass with silicone rubber components.
