Abstract
A fine filter screen assembly comprising a length of filter screen having a relatively fine filtering surface and terminating at opposite ends with opposed end shafts. Generally open connecting means interconnect the opposed end shafts to define a continuous loop structure. At least one removable filter grid having a substantially fine filtering surface is removably mounted between the opposed end shafts such that the continuous loop structure has a substantially continuous relatively fine filtering surface. Removal of the grid allows internal access to the screen assembly.
