Demand valve 4500 PL/D by BartelsRieger
Product information "Demand valve 4500 PL/D by BartelsRieger"
The basic unit 4500 PL/D is a link between the facepiece (e.g. full face mask BRK 820) and the compressed air supply hose DZS 9 to the compressed air source and contains a demand valve with standard thread connection according to EN 148-1. Thanks to the warning device permanently integrated in the demand valve, the residual pressure warning is also given directly to the user when using our pressure reducer DM 1900. Inaudible, dirt resistant and with no additional air consumption.
A distinction is made between units with a continuous flow valve (constant air supply) and units with automatic lung operation. Compressed air supply hoses with demand valves supply air only when the wearer inhales. The air consumption of these devices is lower than that of constant flow hose units.
A compressed air supply hose device with a demand valve is particularly suitable for breathing air supply from compressed air cylinders. A distinction is made between negative pressure and positive pressure devices. Devices with positive pressure create positive pressure in the facepiece. The positive pressure prevents the penetration of hazardous substances from the ambient atmosphere into the respirator mask.
» Fixed warning device integrated in the housing of the demand valve
» Falls into G26 group 1 (ArbMedVV), since weight <3 kg and <5 mbar breathing resistance
» Available in negative and positive pressure with all standard fittings
