ABSTRACT:
A filter apparatus having an inlet duct (30) with a plurality of vanes (10) therein. Each vane (10) is positioned in the fluid duct (30) and adapted for deflecting fluid as it moves through the duct (30) and further for preventing the accumulation on the vane (10) of particulate matter entrained in the fluid. Vane (10) comprises a vane body (11) defining a forward edge portion (12) which faces upstream into the moving fluid. Forward edge portion (12) has a pre-determined angle of incidence to the direction of travel of the moving fluid sufficient to overcome frictional adherence of the particulate matter. Vane body (11) also has a free end (16) spaced apart from the inner walls of duct (30). The vane body (11) also defines a rearward edge portion (13) downstream of forward edge portion (12) and defines an angle within duct (30) corresponding to the extent of deflection to be applied to the moving fluid. One of the embodiments includes alternating vane bodies (11) positioned on opposite walls of the duct (30).
