XY OXYGEN CONCENTRATOR
16 519211-22
EN
The concentrator must be protected against any crash in case of vehicle or fork-lift truck moving.
The oxygen concentrators have to be situated in premises separated from compressed air production devices, vacuum production
devices, cylinder bundle supply, static or mobile cryogenic or non-cryogenic vessels.
When choosing a location, it is necessary to take in account potential risks (like contamination or fire, for example). The premises
must be equipped with a fire detector and all the adequate fire-fighting means. Adequate drainage systems must be installed at that
place.
The air intake(s) of compressors must be situated at a place which offers the minimal possible contamination by:
the exhaust gas system of internal combustion engines (like cars), vacuum system exhaust, medical fluid gas exhaust, anaesthetic gas
exhaust, air ventilation system exhaust and any other source of contamination.
The intake(s) must be equipped with devices against insects, particles and water. Potential effects of local winds must be taken in
account to determine the location of the intake(s).

receiver exhaust valves along with the consumption solenoid valve [V.cons] are to be led to the exterior of the site with
identification at the exit point on the outside façade including recommendations on O
2
risks and ensure safe dispersion in the
atmosphere.
It is advised that the compressed air unit should not be sited in the same place as the concentrator. Not being in the
same place would obviate the risk of closed loop working, which could cause abnormally high nitrogen concentrations,
thus prejudicing good concentrator operation and endangering the health of personnel coming into the site.
AIR PRODUCTION UNIT
7.1 Air quality
Compressed air is the primary material supplied to the O
2
concentrator. On its primary quality depends the quality of O
2
produced,
and the working life of the molecular sieves in columns A and B.
The air supplied to the concentrator should have at least the following characteristics:

Pressure between 8 and 11 bar

Temperature: b5°C and +40°C

Hygrometry: -45°C in uncompressed air

amount of oil: less than 5 ppm

amount of CO
2
: less than 30 ppm

amount of CO: less than 5 ppm

amount of O
2
: greater than 20.9%
Any non-respect of these characteristics will harm the correct operation of the concentrator and risk irreversibly
damaging the effectiveness of the molecular sieves, in particular in terms of hygrometry. Our guarantee will not be
able to apply in these conditions.
We recommend to carry out an analysis of the air quality once a year.
