External Components Description 

 
 
Feed Air In - 

This connection is used to supply the feed air to the oxygen generator.  It is 
located on the left side of the machine as you face it.  A hose or pipe should be 
attached to this fitting.  It should be of adequate diameter to supply air at a 
sufficient pressure and flow rate to feed the generator.  

OGSI

 can assist in sizing 

this line, if necessary. 

 

Feed Air Pressure Gauge - 

This gauge indicates the pressure of the air supplied to the beds after its has 
been regulated and filtered.  While the generator is cycling, this gauge should 
vary between 35 PSIG and 70 PSIG (240 kPa and 480 kPa). 

 

Off /Continuous /Automatic Selector Switch - 

The control switch is used to turn power to the generator on and off and to select 
the mode of operation desired.  Naturally, in the off position there is no power to 
the unit and the light inside the switch remains off. 

When the switch is turned one position to the right (so that it points straight up 
and down), the ‘Continuous’ mode has been selected and the unit will cycle 
regardless of whether or not oxygen is being drawn from the storage tank.  The 
light inside the switch will always be on as well.  The advantage to operating in 
this mode is that oxygen should be available at a slightly higher pressure than if 
in the automatic mode.  How much higher depends on the demand for it.  The 
disadvantage to operating in this mode is that your compressor will run more 
often. 

Turning the switch to the far right position puts the generator in the ‘Automatic’ 
mode.  In this mode a pressure switch is engaged to sense the oxygen storage 
tank pressure.  Once that pressure reaches about 60 PSIG (420 kPa) the 
generator will stop cycling.  When the pressure in the storage tank falls to about 
45 PSIG (310 kPa), the generator will begin to cycle again attempting to refill the 
storage tank.  While in this mode, the light inside the control switch will be on 
whenever the unit is cycling. 

 

Oxygen Pressure Gauge - 

This gauge indicates the pressure of the Oxygen in the storage tank.  While this 
level can vary between 0 PSIG and 65 PSIG (0 kPa and 450 kPa), it should 
remain between 40 PSIG and 65 PSIG (280 kPa and 450 kPa) during normal 
operation.  The exception, of course, is when the unit is first started and it needs 
to fill the storage tank.  This does not take more than a few minutes.
