ABSTRACT:
A disk-type filter comprising a housing having an inlet connectable to an upstream pipe and an outlet connectable to a downstream pipe and a stack of filter units disposed within the housing for separating solid particles from a fluid flowing between filter units in the stack of filter units from an upstream side of the stack of filter units to a downstream side thereof, characterized in that the stack of filter units includes a plurality of co-operating filter units defining a plurality of paired co-operating filter surfaces, including first and second surfaces each defining a plurality of fingers, the fingers defined by the first surface being arranged in registration with the fingers defined by the second surface, the exteriors of the fingers defined by the first and second surfaces communicating with either one of an upstream side and a downstream side and the interiors of the fingers communicating with the other one of the upstream side or downstream side, spaces being defined in association with the fingers defined by the first and second surfaces and being disposed in registration so as to define channels, which permit particulate matter to become disengaged with the upstream side of the fingers defined by the first and second surfaces, the fingers of each disk being joined.
