Model 1826X is the designation of the second extinguisher to be launched in the Nu-Swift range of extinguishers for all fire risks except live electrical equipment above 1000V, unusual inflammable metals such as magnesium and uranium,, and carbon disulphide. It is also suitable for mixed risks, including those complicated by the presence of live electrical equipment or wiring of normal voltages.
The new extinguisher is 67cm (264in.) high, has an overall weight of 20.9kg (461b), and contains a minimum of 12kg (26.41b) of Multi-A Dry Powder. This powder consists of a mixture of ammonium salts, to which other ingredients have been added to ensure long term maintenance of its fire fighting effect and free-flowing properties.
One 12kg extinguisher can extinguish fires in substances such as wood, textile-fabrics and paper of a size equal to that requiring four 10-litre (2.2gal) water-type extinguishers, provided flowing of or soaking by the extinguishing agent is unnecessary. It also provides a heat-shield for the fire fighter.
The extinguisher can be carried, and a trolley is available. Extinguisher and trolley together are known as Model 1826. The trolley (2kg; 441b) can also be used for transporting Pressure Charge No 52 (20kg; 44A), with which Model 1826X can be rapidly reloaded, without the use of spanners.
The powder cloud produced when the unit is discharged has a range of 7.5 metres (25ft), and the duration of the discharge, if uninterrupted, is 28sec at the rate of approximately 450 grammes (11b) per second.
