Air Line Systems
Supplied air respirators are non-freely portable breathing apparatuses. By using an airline respirator, you can supply necessary breathing air from the outside – either from an external airline, such as breathing air compressors, or via breathing air cylinders. There are three different types of airline breathing apparatus: with control valve - providing a continuous stream of air, with normal-pressure regulator - breathing air is used only for the inhalation cycle, and with pressure regulator - e.g. used in atmospheres containing substances that exhibit acute toxicity.
