Inflatable Fresh Air Bay (FAB)
The Inflatable 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 inside the tent access door. Compressed air flows into air-tight structural beams and fills the chamber with breathable air.
The Strata XP-AC battery-powered air conditioner is designed to provide at least 96 hours of air cooling and dehumidifying for individuals occupying a refuge alternative following a mine emergency. The air conditioner prevents potentially lethal heat and humidity build-up in the enclosed area, and creates a comfortable, survivable environment.
The Strata XP-AC can be used with both mobile chambers and built-in-place permanent Safe Rooms.
30 CFR Part 18 and Part 7 approval by the US Mine Safety and Health Administration (MSHA).
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 and highly mobile coal mining environment.
