The pneumatically-balanced ZEO is an engineering marvel of precision, durability and comfort. Its durable chrome-plated marine brass metal valve delivers a phenomenal breathing experience, improves cold-water performance and helps recirculate moisture from exhalation to prevent dry mouth. The breathing adjustment gives the diver a wide range of control to precisely set airflow throughout the dive. The ZEO comes standard with an in-line hose swivel, inhalation effort control, dynamic adjustment technology dive/ pre-dive switch and a super comfortable orthodontic mouth piece featuring an inline ball swivel on the hose connection to eliminate the binding that can cause jaw fatigue. The cold-forged, over-balanced diaphragm FDX-i first stage is environmentally sealed. The in-line design limits the pressure loss inherent in “L” type first stage designs making the FDX-i more efficient and lighter due to its compact form. Second Stage ZEO Pneumatically balanced second stage automatically maintains consistent inhalation effort throughout dive Diver adjustable inhalation effort allows the diver to control a desired level of airflow at any time. Patented Dynamic Adjustment automatically maintains inhalation effort throughout the dive Adjustable Venturi Switch (A.V.S.) for simple dive/pre-dive adjustment Inline ball swivel reduces jaw fatigue Orthodontic mouthpiece Paired with the FDX-i first stage First Stage FDX-i The FDX-i in-line design provides an improved flow rate, greatly reduced weight and more ergonomic port positioning for better hose routing when compared to the classic right angle first stages. Precision Cold Forged Reduced weight Pneumatically balanced – consistent performance at any depth Environmentally Sealed diaphragm – cold water ready 4 Low Pressure and 2 High Pressure Ports Angled ports for ideal hose routing Improved flow rate over standard right angle first stages.
