Portable Fresh Air Bay (FAB)

The Portable Fresh Air Bay is a completely powerless, inflatable refuge chamber that deploys rapidly to provide 96 hours of breathable air to miners trapped underground.
Fully Inflatable

The Portable Fresh Air Bay is folded and stored in an explosion resistant steel container called the Strata Fresh Air Bay Skid. In an emergency, miners locate the Skid and activate air flow using the master control valves. A hinged door on the end of the Skid is opened and the folded Fresh Air Bay is manually rolled out. Inflation is initiated by pulling on an activation cable. Compressed air rapidly inflates the structure, flowing into air-tight structural beams and filling the main chamber with breathable air.

An air-powered carbon dioxide scrubber, food, water, portable toilet and other supplies are accessible from inside the inflated Fresh Air Bay.

MOBILITY & HARDENING PACKAGES

Strata has engineered robust wheel and hitch packages and additional hardening for the Fresh AIr Bay Skid that can be added during construction or retrofitted later. The wheel and hitch package assists in maneuvering the units into and around the mines, significantly reducing wear and tear. The removable steel hitch plate may be attached to either end of the Skid which facilitates the pulling or pushing of the unit.

The additional hardening options strengthen the structure of the Skid, adding protection in the harsh underground environment.
