ABSTRACT:
An apparatus for filtering particulate material from air and for removing the particulate material collected upon a filter is disclosed. The apparatus includes a housing having an air inlet and an air outlet. A hollow longitudinally extending filter is secured within the housing. The filter has an outer surface, an open interior, opposite ends, and a longitudinal axis extending between the ends. The filter is formed of a porous media. One end of the filter is removably secured relative to the housing so that the longitudinal axis of the filter extends generally vertically. The other end of the filter is closed. A first chamber is defined around the outer surface of the filter. The chamber is in communication with the air inlet whereby air moving from the inlet to the outlet passes through the filter into the interior thereof and deposits particulate material on the outer surface of the filter. A mechanism is provided for removing the particulate material collected on the outer surface of the filter. The mechanism for removing the particulate material includes a device connected to the closed end for rotating the closed end and the end of the filter attached thereto to twist the filter.
