Basic device, positive pressure demand valve, thread connector M 45x3
A distinction is made between devices with
a control valve (continuous air supply) and
automatically operated devices (demand valve).
Compressed air-line breathing apparatuses with demand valves
only supply breathing air when the user of the respirator
is breathing in. These devices consume less air than
compressed air-line breathing apparatuses
with continuous volume flow.
A compressed air-line breathing apparatus with a demand valve
is particularly suitable for breathing air supply from compressed-air
cylinders.
One differentiates between negative pressure and
positive pressure devices. Devices with positive pressure generate positive pressure
in the face piece. The positive pressure prevents
the entry of hazardous substances from the surrounding atmosphere into
the face piece.
Compressed air-line breathing apparatus with demand valve
Regardless of the ambient atmosphere, compressed air-line respirators offer the most comprehensive protection against
damaging ambient conditions. The required air is supplied to the face piece via supply hoses i.e. the users move in a defined
operating range during work which is defined by the hose lengths. The breathing air is provided from compressed-air cylinders
compressed-air networks or compressors. In this way, long operating times can be achieved.
