The OMS high performance AirStream first stage regulator was designed to optimize hose routing. It includes 2 high pressure ports and 4 low pressure ports. The development of specialized high pressure ports angled at 45-degrees, keeps gauges closer to the diver’s hips. The 30-degree angled low pressure ports help to ensure optimal trim by guiding hoses to route directly over the diver’s shoulders. The compact design of the Evoque second stage paired with the Airstream delivers a work of breathing (WOB) of .8 joules per liter. OMS designed this system to maximize air flow by simply creating larger passages which provides excellent inhalation and exhalation for the diver. It is also CE certified to EN250 European standards. This regulator will accommodate divers at all skill levels.
