Re: Fw: Product Warning: Air Conditioners for hyperbaric chambers

[Guest guest]

Side note, our chamber does get hot, so we moved it under our ac vent and also

take in a water bottle.

> Critical Product Warning: R22 Freon-based Hyperbaric Chamber Air Conditioners

> Several different versions of R22 Freon-based portable air conditioners are

being sold as accessories for hyperbaric chambers. These units are not designed

to provide breathable air in a contained system. Under certain circumstances

they can be dangerous and even FATAL.

> These air conditioners are designed with a dual-core rechargeable R22 Freon

containment system. The inner coil filled with R22 Freon is completely contained

within an outer coil of air that is ultimately cooled, then piped into the

hyperbaric chamber. If the internal Freon coil leaks in any way or becomes

dislodged, it will contaminate the breathable air in the outer coil as it flows

into the chamber.

> A breach to the inner core or other failures in the structural integrity of

the inner coil can be, and frequently are, wholly undetectable without the aid

of specialized detectors, which is not included with these units. Pin hole

ruptures to the inner coil can be sustained during shipping or through

unintentional mishandling of the unit.

> Any form of Freon inhaled under pressure floods the lungs of the chamber

occupants, which can cause asphyxiation.

> To report the sale of an R22 Freon-based air conditioner for use with a

hyperbaric chamber to the FDA, call .

> If you have any questions or concerns regarding your hyperbaric chamber,

compressors, or accessories, please contact the International Hyperbarics

Association.
