Il gas segue nell’ apparecchio un percorso circolare unidirezionale, in modo che venga espirato sempre verso sinistra ed inspirato da destra. Utilizzando questo tipo di circolazione si ottiene la depurazione integrale del gas espirato, poiché questo è costretto ad attraversare interamente senza vie preferenziali il filtro di depurazione.L’apparecchiatura è costituita da un sacco polmone, un filtro che contiene la calce sodata, dalla flangia di bloccaggio, dalla valvola a tre vie con i tubi corrugati e valvole unidirezionali una bombola ossigeno da lt.2 con valvola dosatrice manuale e manometro alta pressione. Il tutto è contenuto in una protezione in kevlar soffice.Questo piccolo re-breather ad ossigneo a circuito chiuso di tipo ciclico ha le seguenti caratteristiche:
Flow regulator reducer applicable to oxygen cylinders of any capacity with supply valve for continuous oxygen supply from 0 to 30 liters per minute and mask with collection flask and demand valve with transparent silicone mask for the administration of oxygen on request. Adapters and connections are available for all kinds of world standards. The gas follows in the apparatus a unidirectional circular path, so that it is always exhaled to the left and inhaled from the right. By using this type of circulation the integral purification of the expired gas is obtained, since this is forced to pass through the purification filter entirely without preferential paths.The apparatus consists of a lung bag, a filter containing the soda lime, from the flange of locking, from the three-way valve with corrugated pipes and one-way valves, an oxygen tank of 2 liters with manual metering valve and high pressure gauge. Everything is contained in a soft kevlar protection. This small cyclic type closed loop re-breather has the following characteristics:- Autonomy 4 hours approximately with lt.2 cylinder- 9.5 liters bag capacity- Lung bag material is coated polyurethane- Capacity of the tank lt.2 / 200 atm- Dimensions 400 mmX400 mmX110 mm- Cyclical oxygen recirculation with 1.5 kg soda lime filter. radial absorption -Weight 6 Kg
