Isolating Respiratory Protection: Compressed Air Hose Units

Insulation devices work independently of the ambient atmosphere. They offer protection against oxygen deficiency and harmful atmospheres. The wearer is supplied with breathing gases that are not harmful to health. They are used when there is not enough oxygen in the environment, the environmental conditions are not known or when pollutants cannot be filtered or are poorly / not at all perceptible.

Insulation devices consist of an ambient independent air source (e.g. breathable compressed air from a compressor / compressed air network) a compressed air hose, a carrying device, a compressed air control valve, a breathing air hose, a breathing connection and a compressed air filter station.

The compressor continuously supplies breathable compressed air via a compressed air hose to the wearer’s compressed air control valve. the wearer can adjust the flow rate of the volume flow at the control valve, which is then fed to the wearer’s breathing connection via the connected breathing air hose. An overpressure is created in the breathing connection, which prevents pollutants from directly entering the head part.

The compressed air supplied by the compressor must have breathing quality according to EN 12021. If this is not the case, an additional compressed air filter station must be used.
