text: An ambient pressure is low enough that you can safely and comfortably breathe.
text: The efficiency of dehumidification and filtration depends on significant compression and limited flow velocity, which requires back-pressure at the final stage outlet to resist flow when the filling pressure is low.
text: On land they are used in industrial applications where poisonous gases may be present or oxygen may be absent, firefighting, where firefighters may be required to operate in an IDLH atmosphere for extended periods, and in hospital anaesthesia breathing systems to supply controlled concentrations of anaesthetic gases to patients without contaminating the air that the staff breathe, and at high altitude, where the partial pressure of oxygen is low, for high altitude mountaineering.
