AirStream 1 First Stage Regulator

AirStream 1 First Stage Regulator


Availability: Special Order

Part Number:OM50125 Manufacturer: OMS CONNECTION:


This high performance regulator was designed to optimize hose routing. The development of specialized high pressure ports (HP) angled 45-degrees, keeps gauges closer to the diver’s hips. The 30-degree angled low pressure ports (LP) of the AirStream help to ensure optimal trim by guiding hoses to route directly over the diver’s shoulders.

As a diver moves underwater they quickly learn that streamlined gear is critical to diving efficiently and conserving gas. One of the main features of the high-performance Airstream Evoque is the streamlined hose routing of the first stage. The low-pressure ports are angled 30-degrees down and 23-degrees forward to allow hose routing directly over the shoulders keeping the configuration close to the diver’s body. Additionally, the high-pressure ports are angle down 45-degrees for minimal resistance and keeping the SPG as close to the divers’ side as possible. The high-performance Airstream Evoque delivers the industry’s finest work of breathing (WOB) of .8 joules per liter.
