Abstract: An apparatus for affecting air includes a housing. The apparatus includes a treatment layer disposed in the housing for treating air. The apparatus includes a fan. The apparatus includes a gas powered motor mechanically engaged with the fan to operate the fan which forces the air through the treatment layer. The apparatus includes a compressed gas tank in fluid connection with the gas powered motor to provide gas to the motor to power the motor. A method for affecting air.

Abstract: A method for a miner in a mine to breathe in the mine having the steps of turning on an on off valve of a first air cylinder while in the mine so air flows from the first air cylinder connected to a first port of a connector to and through a third port of the connector and to a facemask on the miner's head. There is the step of the miner breathing air in the facemask from the third port. There is the step of connecting a second air cylinder to a second port of the connector. There is the step of turning on an on off valve of the second air cylinder while in the mine so air flows from the second air cylinder to and through the third port and to the facemask so the miner is breathing air in the facemask from the first and second air cylinders. There is the step of separating the first air cylinder from the first port while in the mine. A system for a miner in a mine to breathe in the mine.

Abstract: A refuge chamber for miners in a mine includes a skid. The chamber includes a tent that is disposed in the skid in an undeployed state which is expandable to a deployed state and extends from the skid to provide a protected atmosphere for the miners. A method for providing a refuge chamber for miners in a mine including the steps of opening a skid made of metal. There is the step of expanding a tent that is disposed in the skid in an undeployed state to a deployed state that extends from the skid to provide a protected atmosphere for the miners.

Abstract: An apparatus for cleaning air includes a housing having a chamber. The scrubber includes a carbon dioxide scrubber layer disposed in the chamber which claims carbon dioxide from air passing through the scrubber layer. The scrubber includes a forcing element which draws the air into the scrubber and forces the air through the scrubber layer which is powered without any electricity. A system for supporting a breathable environment for users. The system includes an enclosure. The system includes an air scrubber disposed in the enclosure which cleans carbon dioxide from air in the enclosure that is powered without any electricity. A method for cleaning carbon dioxide from air. The method includes the steps of flowing compressed air through a fluid driven motor to operate the motor without any electricity. There is the step of rotating a fan with the operating motor.
