SELF-CONTAINED OPEN-CIRCUIT COMPRESSED AIR BREATHING APPARATUS APS/3N-2040 TYPE

Application

Compressed air breathing apparatus APS/3N-2040 type is a respiratory protective device designed for work protection purposes, rescue operation, fire fighting work, on ships, used to guide endangered persons to safety from dangerous environment. Breathing apparatus is also for industrial applications. Apparatus enables the user to breathe in case of oxygen deficiency and in the presence of harmful substances at the optional concentration of ambient atmosphere unless aggressive chemicals affect destructively the unit or disturb its satisfactory operation. Breathing apparatus can be used in the temperature of ambient atmosphere within the range from -30°C to +60°C.
When an accident happens and there is danger of poisonous and aggressive media such as toxic industrial agents (TSP), toxic warfare agents (BST), radioactive substances and biological agents in all possible form as solids, liquids, aerosols and vapours, which could affect destructively the device and disturb its operation as well as poison the user through the skin, breathing apparatus should be worn together with protective gas tight suit and protective gloves.

The apparatus does not protect the user against infection through the skin.

The apparatus must not be used as diving apparatus.
Parameters of breathing apparatus except mass are in compliance
with PN-EN 137.
