Invacare® HomeFill® II Oxygen System

8 Technical Data

8.1 Technical Description

The HomeFill II Oxygen System (IOH200AW) is an
electro-mechanical prescription system for use in the home. Its
intended function and use is to supply pressurized oxygen to fill
Invacare proprietary gas cylinders for ambulatory use while the
patient receives therapeutic oxygen from an oxygen concentrator.
The IOH200AW gas system is designed for use with an Invacare
oxygen concentrator with an integral HF2 accessory port that can
supply a gas concentration greater than 90% O
while supplying a patient therapy flow rate.
The maximum oxygen concentrator flow rate for patient use
is listed in the table below. Otherwise, the oxygen level to
the compressor will be <90% and the compressor will not
fill the cylinder.

The HomeFill II Oxygen system consists of IOH200AW gas
compressor, connection tubing, and the Invacare supplied portable
gas cylinders with the integral flow regulator and interlocking fill
fitting.
The IOH200AW compressor consists of a multistage compressor,
internal reservoir, control electronics with an integral oxygen
concentration sensor, interlocking fill fitting, inlet fitting, and drive

motor. The compressor operation is controlled by the electronics
assembly. The motor/compressor is allowed to fill a cylinder only
when the oxygen concentration of the inlet gas stream is greater
than 90% and the cylinder pressure is not already greater than 1500
PSI (10342 kPa). The motor/compressor fill operation is completed
when the gas in a cylinder reaches the maximum fill pressure of 2000
PSI (13786 kPa).
The IOH200AW compressor can fill cylinders for portable use by
ambulatory patients. The Invacare supplied portable gas cylinders
have an interlocking fill fitting that mates only with the Invacare
IOH200AW compressor assembly. The gas cylinder also contains an
integral flow regulator with fixed, selectable flow settings.
