The Oceanic EOS FDX10 combines a high performance environmentally sealed diaphragm first stage with an effortless breathing balanced second stage to offer excellent cold water reliability, comfort and exceptionally low inhalation resistance.
The FDX10 First Stage uses an over-balanced diaphragm design to progressively increase the intermediate pressure as depth and gas density increase. This provides the diver with a consistent level of high performance and air flow.The diaphragm is protected from contamination and the effects of extreme cold water by an environmental seal that allows the surrounding ambient pressure to be transferred into the first stage whilst helping to prevent free flow conditions and ice crystal build up around critical components. The cold forged First Stage body has four low pressure ports and two high pressure ports that are pre-angled for optimal hose routing.
The EOS Second Stage continues the high performance with a lightweight housing and pneumatically balanced valve. An inline hose swivel helps to alleviate jaw fatigue and allow the diver to move freely without the hose pulling. The EOS is fitted with a diver adjustable inhalation control that alters the breathing resistance required to open the valve. This feature was initially designed to allow divers to set their regulators for optimal performance at depth but would require adjustment when ascending and descending to maintain the same performance level. The EOS dynamically adjusts the inhalation resistance to the performance level the diver sets throughout the dive so there is no need to manually adjust it. The EOS also incorporates and Pre-Dive/Dive mode adjustable venturi system that allows easy manipulation of the air flow within the housing. In the Pre-Dive position air is directed back towards the diaphragm to help prevent free flowing on the surface or set to the Dive position for optimal and venturi assisted flow towards the mouthpiece for maximum performance.
