Filtering half-mask for protection against aerosols with additional protection against vapours and gases "Respirator "SPIRO-312

The Respirator "SPIRO-312 E" FFP2 NR D A/B/E" is a moulded half-mask with exhalation valve and adjustable headband tapes without clips to fix the ends, covering the nose, mouth and chin of the user; it consists of layers of non-woven material outside and inside, a layer of high-efficiency filtering material. It is intended for use as a means of personal protection of human respiratory organs in the presence of harmful aerosols (dust, smoke, fog), as well as vapours of organic compounds, inorganic gases in the air of the working area. It is a disposable product, designed for use at a concentration of oxygen in the air of the working area of not less than 17 volume per cent. The presence of an exhalation valve allows you to reduce the resistance to human breathing on exhalation, as well as to avoid moisturising the filtering and absorbing materials with exhaled air and provide the possibility of effective operation of respirators for a longer period of time.
