Description
It's quiet because it's the Divator, quite the most efficient demand valve ever approved to EN250..check out the videos DIVATOR: General Specifications for 'AGA' mask and Demand Valve Assembly detail: Options Special features Test Protocol Notes: Mask Assembly: Low volume optically correct visor, plastic parts are glass filled nylon 12; mask made from Grey, Natural, SBR and Neoprene rubber compound Helios helmet and head lamp Elastic and strong, comfortable fit for most adults This version is recommended for most users. EN136 A variety of hose options are available but the mask and demand valve assembly does not come with a supply hose in the price. Mask Assembly: As above but outer & inner mask is made from Yellow silicone rubber compound Helios helmet and head lamp Resistant to perishing but not as strong as the grey mask EN136 As above. All metal components of the mask are 316 stainless and nickel or chrome finished Brass 121. Inner Mask Fitted to all full-face masks Reduces re-breathing of Carbon dioxide to lower than ½% Volume EN136 Hypoallergenic rubber Demand Valve Assembly Automatic compensation for supply gas pressure changes and ambient pressure. Standard pressure. Valve responds at ambient pressure minus 5-mm water gauge. This unit can be fitted with “off” switch; useful if the valve is used as a spare Fully balanced downstream valve with built in pressure relief and safety purge design. Work of Breathing less than 1 Joule/litre, response time less than 30 milliseconds EN250* Plastic parts are glass filled nylon 12; metal components of the mask nickel or chrome finished Brass 121. Demand Valve Assembly Automatic compensation for supply gas pressure changes and ambient pressure. Positive pressure valve As for standard valve but external pollution is kept out of the mask and the lungs increase gaseous exchange area, achieving better gas perfusion. EN250 As above Suitable Air supply via ¼” id. supply hose >1000 Litres per minute at a dynamic pressure exceeding 6.5 Bar This will be achieved with any Pressure Reducer meeting EN250. The Divator reducer unit is ideally suited. E250 Measured at unopposed 3/8” unf, reducer port at ambient pressure of 1 Bar. What is standard? Mask and front port plate. Instruction manual Demand Valve, balanced pressure type Suitable for use with oxygen up to 20 Bar What is extra, which might be desirable? Prescription glasses and fitting kit Buddy phone communications Supply hose Diving with a buddy who is also equipped with the World’s best demand valve Welding visor Mouth piece for “sports” conversion Speech diaphragm Hard wire communications Dive gas control manifold Quick release hoses If further detail is needed; please submit an enquiry in 'contact us', or telephone a technician, on: 01952 461541
