Breathing Mask

This Oronasal breathing Mask is dedicated to the Wall-mounted Demand Regulator BIBS system.
It may also be used with the Free Flow Breathing system when the Oxygen supply is connected to the O2 bag instead of the Mask.


This mask is much lighter and comfortable than the usual BIBS mask which has to support the weight of the Demand Regulator.

The Oronasal Mask inlet may be switched from central position to the side to accomodate the Wall-mounted Demand Regulator location in the chamber.

The mask is available in 3 sizes : S, M and L.

It has been specially designed to breathe oxygen-rich mixtures used in hyperbaric oxygen therapy or by divers during chamber decompression.
The exhale breathing gases are evacuated to the outside through the dump circuit so that oxygen concentration in the chambers remains at acceptable level.

The mask is fitted with 1 inhalation Valve and 1 exhalation Valve.
The mask inlet and outlet are dia. 22 mm straight hose connectors that may easily be adapted to any LP hoses. This is particularly interesting for those who prefer to use disposable hoses rather that our standard heavy-duty corrugated hose.
