Oxygen Concentrator

The AHA O22 oxygen concentrator is a stationary oxygen concentrator. The unit extracts oxygen from surrounding air at standard atmospheric pressure, designed for 24/7 use and can be portable. The unit is built to be as strong as an industrial oxygen generator. The unit take approximately two minutes after initial start-up to achieve maximum oxygen purity.

  • Oxygen Pressure: 0-2.3 bar
  • Purity: 93% +/-3% at 3.2 ATA
  • Power: 700 Watts
  • Dimension (WxLxH): 43 x 26 x 71 cm
  • Noise: 65 dBA

Hyperbaric Chambers
AHA Flex 20 V2

The AHA Flex 20 V2 is a medical hyperbaric chamber with a working pressure of 200 kPa (2.0 bar, 2.0 ATA or 15 psi) and a Class IIb Medical Device (MDD 93/42/EEC) certification. The chamber is designed for 3.0 ata (300 kPa) of pressure, with higher pressure and oxygen concentration capability for medical purposes. The chamber is developed using a three-layer design patented by AHA Hyperbarics and using a urethane material. It has a semi-transparent interior, six windows, stainless steel fittings, and is lightweight to help relocation. And there is the AHA Air 22 air compressor, internal frame, mattress, anti-roll bolsters, air hose, instruments, special breathing system with oxygen exhaust and oxygen monitor included.

AHA Flex 18 V2

The AHA Flex 18 V2 is a medical hyperbaric chamber similar to the AHA Flex 20 V2 with a working pressure of 180 kPa (1.8 bar or 12 psi). The other specifications of the AHA Flex 18 V2 is the same as the AHA Flex 20 V2.


The AHA Fit is built in two models, the AHA Fit 20 and 18, capable of 200 kPa (2.0 bar, 2.0 ATA or 15 psi) or 180 kPa (1.8 bar, 1.8 ATA or 12 psi). The AHA Fit is intended for use in various medical purposes and can be adapted to different pressures. The materials used for the AHA fit are built to not oxidize or deteriorate in exposure to a high concentration of oxygen. Each hyperbaric chamber is build without glue and is manufactured using a high frequency computer guided welding machine. It uses a three layer design patented by AHA Hyperbarics and using urethane material. Each chamber comes with the AHA A22 air compressor, internal frame, mattress, anti-roll bolsters, dual mask adapter, air hose and instruments.

AHA Vita

The AHA Vita is a monoplace, inflatable and portable hyperbaric chamber focused on vitality and relaxation rather than medical use. The chambers operating pressure is 1.7 bar / 10 psi / 170 kPa with a maximum designed pressure at 2.0 bar / 15 psi / 200 kPa. The design is composed of three layers (inner bag, outer bag and a green grid). The chamber is dressed in green, with a diameter of 85 cm (34 inches) and a length of 250 cm (98 inches) to offer a larger space for comfort. The AHA Vita is rated for 2000 hours of use. Accessories include cotton clothes, sheet, pillow, cleaning solution and oxygen masks. The chamber can be supplied with oxygen either by the AHA O22 oxygen concentrator or oxygen tanks.
