ABSTRACT:
An air scrubbing and purifying system is provided for effecting removal of combustion products from contaminated air generated by a fire in progress in an enclosed room. The system comprises (a) electrically-powered intake fans for withdrawing contaminated air from the enclosed room, (b) air washing and filtering stations adapted to treat and remove soot, smoke, and other combustion-product gasses from the contaminated air, and (c) electrically-powered discharge fans for impelling the treated air into the enclosed room. The system is actuated and made operational by means of a smoke or fire detector and is powered by integral batteries kept in a charged state by an appropriate trickle charging device. The system is advantageously disposed within a door structure for the enclosed room and may include extendable seal strips at the peripheral surfaces of the door to aid in sealing the enclosed room from adjacent areas. The air washing station includes a reservoir for storing the washing fluid which may be ordinary tap water, and the air filtering station may include activated charcoal.
