Depending on the industry, the type of mine/operation and the country/region, the airlock is either a mandatory or an optional refuge feature. MineARC can assist you with information on the Guidelines/Regulations relevant to you.

MineARC's Airlock System incorporates a double-door design with push-button flushing, with occupancy varying depending on the model of the refuge. The entry door opens externally due to positive pressure from the airlock flushing system. The airlock door opens inwards to the main refuge. Both doors have explosion proof portal windows for viewing into the airlock and main refuge.

Before entry of the airlock, the first flush is commenced by activating a push-button outside the refuge. The occupant then enters the airlock and activates the second push-button before entry into the main refuge.

The airlock compartment contains low pressure and high pressure cylinders, provides 100% volume air exchange with each flush, and is completely stand alone for up to 60 flushes, if required.
