L'explication/l'anotation:To protect body of human respiration from aerosols (dusts, smoke, fog) concentration to 100 ìã/ì3 in case of simultaneous presence of acid gases (HCl , SO2) concentration to 5 maximum permissible concentrations, HF - to 15 maximum permissible concentrations.
La description détaillée de marque:Device:
the Ëåïåñòîê-Â respirator is supplied in the form of circle, which collects in half-mask by the yourselves user. In the manufacture of respirator new filter material of modulation transfer function, on efficiency similar material of ÔÏÏ, which is used in ØÁ-1 respirator "of Ëåïåñòîê-200", but constructing smaller breathing resistance, as well as the sorption material, intended for absorbing of acid gases.
the technical characteristics is used:
initial resistance air flow
at a flowrate of 30 ë/ìèí, p,. Not more 40 penetrations coefficients of aerosol
through filtering the part, %,. Not more 2, 0
the protection of respiratory organs is carried out with the help of ïðîòèâîàýðîçîëüíîãî and sorbing elements. Sorbing the element is on the outside of respirator. The Ïðîòèâîàýðîçîëüíûé element is on the inside of respirator under strut. Safeguard against aerosols penetration from operating zone, as well as play a role of protective shield, averting the fibers hit of material sorbing element into the mouth.
requirement for safety:
the respirator efficiency depends on careful adjustment.
is forbidden to use the respirator, having the end-to-end holes, the damages of filtering or sorbing elements.
the respirator do not protect against nitric oxides. Its impossible to apply for protection against specially hazardous gases with narrow band of acute action, for example - hydrocyanic acid.
attention! Impossible to apply the respirator in cases of, wherever possible the low oxygen content into the air (closed capacity, wells etc).
manufacturer's warranty:
average life of respirator - to 3 changes. According to dispersion and concentration of dust and harmful substances, the lifetime can vary.
the guarantee storage life of respirator - 2 years. |
