Required Operating Conditions
Location of Machine:
This standard oxygen generating system is intended for use indoors in a commercial
or light industrial setting. The enclosure meets
NEMA12
protection guidelines, which
provides a degree of protection against dust, falling dirt and non-corrosive liquids.
Feed Air/Ambient Air Quality:
The life of any PSA oxygen generator is directly related to the air quality that is
fed into it. Hot, humid, dirty, oily air deteriorates and degrades the performance of the
molecular sieve. In order to preserve the effectiveness and extend the life of the oxygen
generator, precautions must be taken to ensure that the air provided is cool, dry, clean and
oil-free.
Changing the inlet air filter is a simple and easy way to provide the unit with some
protection. It is advisable to operate the unit in an air-conditioned or a well-ventilated area.
The room should also be free of toxic gases and high concentrations of hydrocarbons,
especially carbon monoxide. Humid, oily areas should be avoided as installation sites as
much as possible.
Ambient Air Temperature:
The machine is designed for use over a temperature range of
40
F
to
100
F
(
5
C
to
38
C
). Since hot air has the ability to hold more water in the form of humidity than cool air,
operating the unit in hot areas will reduce the effective life of the molecular sieve.
Note:
Operation outside of this temperature range will not be warranted by
OGSI
.
Electrical Power:
On U.S. models, the power for the control circuitry of the oxygen generator is a
single-phase electrical supply of
115 VAC
and about
6 A
at a frequency of
60 Hz
.
This equates to approximately
700 W
of power. It is required that a
10 A
circuit
be dedicated to each
OG-15/OG-20
unit. Additionally, the unit must be connected to
this circuit using only the supplied power cord, and without the use of additional
extension cords.
Feed Air Requirements (OG-15ECompressor-less Only):
An incoming air pressure of
4 SCFM or 6.3 Nm
3
/h
for
OG-15
and
4.9 SCFM or
7.7 Nm
3
/h
for
OG-20
at
30-45 psi (2.1–3.1 bar)
is required for proper functioning of this
machine. The air should be cool, dry and clean, filtered to remove any contaminants such
as dust particles and moisture. It is recommended that it meet the requirements of
ISO8573.1 Class 1.4.1
.
Positioning:
The unit must be operated in an upright position only, with no obstruction
blocking airflow around the unit.
