Product Description

Standard service routine: for positive and negative pressure masks: includes complete disassembly of demand valve, checking and removal of corrosion to metallic components, Ultra-sound cleaning of all components, checking all parts for integrity and proper function, rebuilding and lubricating, replacing hose connection O-rings and inner mask discs and testing the hose to 20 bar.

After adjustment, your mask is tested according to EN250 and the Manufacturer’s maintenance manual. Dynamic performance tests are recorded and noted against the job number, which record we keep for five years, as is required under CoSHH regulations (breathing apparatus) and BS EN 529:2005 (Respiratory protective devices. Recommendations for selection, use, care and maintenance).

Should other parts be required, we will advise you, prior to fitting them. When other parts, such as demand and exhation diaphragms are required, they are charged extra at our published prices.

Usually, other O-rings and rubber parts will need replacement after about six years of service, dependent of the amount of use and the degree of after use care and cleaning you have given the mask.

Return carriage is charged at cost, unless customers collect from our premises.

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
