Breathing Apparatus Spasciani RN/ A 2683 C | SCBA Spasciani RN/ A 2683 C

Breathing Apparatus Spasciani RN/ A 2683 C | SCBA Spasciani RN/ A 2683 C RN/ A 2683 C is a Self Contained Breathing Apparatus designed for long-lasting interventions mainly for inspection purposes to chemical and industrial plants where there is, or may be, oxygen deficiency in the air. RN/ A 2683 C adds on maximum safety and comfort the efficiency, versatility and simple use of the MK2 System, as well as the astonishing field of vision of the Spasciani TR 2002 A mask. RN/ A 2683 C is fitted with an automatic demand valve which keeps a positive pressure in the mask thus avoiding any possible inward leakage of contaminated air from the outside. Should it become necessary the positive pressure mode can be activated by acting on the special button that acts as a supplementary air command, too. The demand valve is connected to the medium pressure hose by means of a quick coupling which allows to disconnect it very easily for maintenance . RN/ A 2683 C takes advantage from the unique MK2 System warning built into the demand valve. This is activated when the pressure left in the cylinder drops below 55 bar. The signal originates from a sounding vibration caused by every inhalation. In this way the full capacity of cylinder is made available to the user for breathing. The acoustic warning is related to the respiratory frequency of the user and allows the user to distinguish his own signal from that emitted by nearby fellows or noise ( Self Test Function) . The location of the warning device protects it from frost or dirt. The back plate is made of blow moulded polypropylene, it is extremely robust and anatomically shaped to allow a comfortable distribution of weight and remains steady on the wearer’ s back even when crouching or crawling. The supporting harness is provided with a special padding to increase comfort and is equipped with a soft belt in the hips area to increase portability of the equipment. Special handles integral with the backplate are provided for carrying the set along. The pressure reducer keeps the outlet pressure constant throughout the emptying of the cylinder and is connected to an easy to read phosphorescent gauge. The reducer is equipped with a twin cylinder connection for attaching two composite cylinders having a capacity of 6, 8 litres with a pressure of 300 bar and is fitted with a valve according to EN 144. RN/ A 2683 C can also be used in conjunction with a wheeled BA Spasciani RC or an air line feeding system by means of the optional 4-way valve.
