ABSTRACT:
An exhaust hood with filter apparatus and having at least a fume collection chamber, an exhaust chamber and an interior wall therebetween having an opening therein through which the collected fumes may pass to exhaust. An exhaust filter exchanger is mounted in the exhaust chamber and has at least two filter holders each for holding at least one filter, with one of the filter holders being in an operating position across the opening in the wall between the two chambers and the other of the filter holders being in a reserve position within the exhaust chamber. The filter exchanger apparatus allows an attendant to retract, rotate, and extend the filter holders (and filters therein) to exchange their positions. Spray nozzles are provided within the exhaust chamber to wash the filters held in the reserve position without removal from the hood. The filter holders are designed to release the filters and the hood includes an access opening to allow the attendant to enter and remove the filter or filters held by the filter holder which is in the reserve position.
