Pressure Regulator –
The regulator controls the air pressure into the machine. This should be set
around 70 psi. Turning it clockwise increases the delivery pressure while turning
it counter-clockwise decreases the delivery pressure.
Product Check Valves –
The check valves insure that the oxygen flow stays directed in the right direction
by not allowing any back flow through the opposite bed.
PLC –
The PLC (Programmable Logic Controller) controls the operation of the machine
and communicates with the touchscreen (on machines equipped with this
option).
Hours Meter –
The hours meter increments time while the unit is running. It provides an
indication as to when service intervals are due.
Noise Muffler -
The noise muffler is used to silence the exhaust noise that occurs as a result of
the sieve beds rapidly depressurizing to atmospheric pressure, venting their
nitrogen. For installations where a lower noise level is required,
OGSI
offers an
optional alternative muffler system that can decrease the emitted noise even
further.
Back Pressure Regulator –
The back pressure regulator controls the flow of oxygen from the machine.
Turning it clockwise increases the oxygen flow rate from the machine (while
reducing the oxygen concentration). Turning it counter-clockwise decreases the
oxygen flow rate from the machine (while increasing the oxygen concentration).
