RN is a Self Contained Breathing Apparatus designed for maintenance interventions in chemical plants and industrial areas, for rescue intervention and, generally, in all cases where there is, or may be, oxygen deficiency.
RN 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.
The back plate is made of vacuum formed 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 with a soft belt in the hips area which increases portability of the equipment. All harnesses and padding are in aramidic and para-aramidic material and self-extinguishing foams. Special handles integral with the backplate are provided for carrying the set along.
The pressure reducer keeps the outlet pressure constant throughout emptying of the cylinder and is connected to an easy to read phosphorescent gauge. The cylinder has a pressure of 300 bar and is fitted with a valve according to EN 144.
RN 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.
RN can be equipped with two different type of masks in EPDM and silicone:
TR82, classic design
TR2002, modern design.
Both these models are available with threaded or bayonet connector.
RN can be supplied with demand valve type A or BN.
