APPLICATION
Compressed air line breathing apparatus UWS 2/21, 2/22, 2/23, 2/31, 2/32, 2/33 fitted with a full face mask are designed for the protection of the wearer`s airways against toxic gases and vapours during work in environments with hazardous chemicals or dust.
DESIGN The complete apparatus consists of: body harness, pressure reducer attached to the belt, panoramic full face mask, demand valve, air supply hose set designed for: UWS 2/21 and 2/31 - length of the hose is 100 m, UWS 2/22 and 2/32 - length of the hose is 60 m, UWS 2/23 and 2/33 - length of the hose is 30 m and it is reeled so that total length of the hose could be quick unreeled.
– Air cylinder set including:
a) four compressed air cylinders;
b) cylinder connecting set-enables air to flow from cylinders to pressure reducer;
c) pressure reducer;
d) complete body harness: - complete connector-enables air cylinder set to be attached to air supply hose set and next without stop the work,
– another air cylinder set can be connected - case where unit is housed and stored
