The Zeagle Envoy II first stage regulator has an internal structure that allows for direct airflow through the 1st stage, providing outstanding performance. Zeagle’s conical precision stainless steel high-pressure valve and advanced polymer seat provide much greater reliability and service life compared to conventional designs, while improving responsiveness and performance at all breathing rates. High performance porting in a balanced diaphragm design along with Dry Environment Seal with Hydro Transmitter makes this one clean regulator first stage that will give you years of corrosion free service.
The balanced diaphragm, chrome plated marine brass first stage regulator is inherently environmentally sealed. The benefit of this type of first stage design is that none of the delicate internal parts are exposed to contaminants such as salt, sand, chlorine or pool acids. These environmental contaminants can cause corrosion and mineral deposits to form on the internal mechanism deteriorating regulator performance. The first stage regulator has 5 low pressure (LP) ports 3/8″-24 UNF thread and 2 high pressure (HP) ports 7/16″-20 UNF thread.
The Envoy Second Stage is lightweight, compact and comfortable. Its design features include Venturi (Free-Flow) control and built in heat-sink for added freezing resistance. Over the years, evolutionary design changes have created a regulator that is resistant to free-flow on the surface, with incredible smoothness and ease of breathing underwater. This pneumatically balanced downstream demand valve second stage regulator is manufactured from brass, flexible and ridged thermoplastics, elastomeric polymers and silicone rubber. The standard hose measures 30″ (76 cm) and is 3/8″ threaded.
The complete regulator weighs 3.22 lbs (1,461 g), comes with a comprehensive owner’s manual, is Nitrox ready to 40% out of the box.
