Working Principle
Air enters the compressor after filtered by the air inlet filter and is
compressed into molecular sieve tower for separation of oxygen gas and
nitrogen gas. Then, oxygen gas passes through the molecular sieve tower
and enters the fine sieve tower smoothly, while nitrogen gas is discharged
into the atmosphere through the separating valve after adsorbed by the
molecular sieve. After the concentration of oxygen gas is further increased
in the fine sieve tower, the flow rate is controlled by the flow control valve,
and then oxygen gas is wet through the humidification water tank and
finally flows through the oxygen delivery pipe for supplementary oxygen
inhalation by users.

The machine makes
a "puff" sound every
few seconds.
After start-up, the
machine runs
normally and the
flow is small.
After start-up, there
are bubbles in the
water tank while no
oxygen gas is
output from the
oxygen outlet.
At the beginning of the
machine use, the connecting
pipe and other plastic parts
will emit odor, which is a
normal phenomenon.
The water level of the
humidification water tank
exceeds the max. water level,
and the air flow presses the
bubbles into the suction pipe.
During long-term use of the
machine, the water vapor in
the air flow converges on the
pipe wall.
This is the sound generated during nitrogen emission when
the machine is normal, which is a sign of good operation of the
machine.
The flow is relatively smalllow.
The oxygen inhalation tube is
kinked or blocked.
The connecting pipe inside the
machine falls off or breaks.
The rubber plug of the
humidification water tank is not
properly inserted.
Turn up the flow gear.
Straighten out the inhalation
tube.
Disconnect the powercord and
contact professionals to repair
it.
Take down the humidification
water tank and insert it properly.
Check whether the humidifica-
tion water tank has not been
cleaned or replaced for a long
time, leading to unpleasant
odor in the water tank.
Clean the oxygen inhalation
tube and humidification water
tank.
Reduce the water in the
humidification tank to be below
the max. water level.
Pour out water in the water
tank, and then add water to the
water tank after no water flows
out from the oxygen outlet.
This is normal odor from
silicone tube and ABS plastic
parts. It is tested to be non-toxic
and harmless, and will
gradually disappear with the
use of the machine.
