Puritan Bennett Companion 1000, 1000T, 550, 500

The companion portable is compact, lightweight device that provides you with a portable supply oxygen.  You will fill the portable from the companion stationary unit.  Portable units include the Companion 1000 (a one-liter model with a maximum flow rate of 6 liters per minute [L/min]) and the Companion 1000 Transport (a one-liter model with a maximum flow rate of 15L/min).  Smaller portable units include the Companion 500 (a half-liter model) and the Companion 550 ( a half-liter model with a pneumatic demand valve that can roughly double your available use time by allowing oxygen to flow only when you breathe in).

Product Features:


  • Vent Valve:  used to fill the unit.  Pull down the vent valve lever to fill the Portable when it is connected to a stationary unit.  Return the vent valve lever to its original position to stop the fill.
  • Fill Connector: used to connect to a stationary unit.  The female fill connector is located on the bottom of the Portable.
  • Flow Control Knob:  used to set the correct oxygen flow to your prescribed rate.
