|
APPLICATION: Compressed air breathing apparatus APS/3N-4080 type as respiratory protective
device is designed for protection of user's airway during specific rescue operation underground in very hard work conditions i.e. in the raised microclimate. Breathing 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..Parmeters of breathing apparatus except mass are in compliance with PN-EN 137. The apparatus does not protect the user against infection through the skin.
The apparatus must not be used as diving apparatus.
