Product Description

Standard service routine: for positive and negative pressure regulators: 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 testing the hose to 20 bar.

After adjustment, your regulator 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.

Test Protocol

Notes:

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.
