49 decibels, quiet enough for hatchery rooms, aquarium plant rooms and clinical spaces.

AirSep Onyx Oxygen Concentrator

Up to 95.5% oxygen concentration, separated from ambient air by pressure swing adsorption.

Onyx gives 5 LPM at 9 PSI and Onyx Ultra gives 10 LPM at 20 PSI — pick on both the flow you need and the back pressure the unit has to overcome.

No — the compressor is built into the unit, so it runs from a power point with no external air supply.

Yes — regulator and flowmeter manifolds to connect the Onyx to Clearwater ozone generators are available separately.

Step up to an OXYMAT PSA oxygen generator — the Half Pallet Series starts at 44 LPM at 93% O₂ and 4 bar(g).

A self-contained oxygen concentrator that produces oxygen from air for tanks, holding systems and live transport.

Product Information

Two models — Onyx at 5 LPM and 9 PSI, and Onyx Ultra at 10 LPM and 20 PSI, both at oxygen concentration up to 95.5%
Self-contained: the air compressor is built in, so there is no separate compressor, dryer or air line to install
Quiet at 49 dB, so it can sit in a hatchery room, aquarium plant room or clinic without noise treatment
Transportable on a sturdy roller base and microprocessor controlled for steady, unattended running
High-impact polystyrene enclosure; rated for 5°C to 40°C ambient and 0% to 95% relative humidity, non-condensing
Suits aquaculture, hatcheries, aquariums, hydroponics, veterinary and medical oxygen duties
Regulator and flowmeter manifolds are available separately to connect the Onyx to Clearwater ozone generators
Sizing: choose on the oxygen flow you need and the back pressure you have to push against — Onyx delivers 5 LPM against 9 PSI, Onyx Ultra 10 LPM against 20 PSI, so take the Ultra if you are feeding a diffuser, cone or ozone generator that needs more than about 9 PSI. Above 10 LPM, step up to an OXYMAT PSA generator.
