ABSTRACT:
A dirt and debris screen for liquid cooled internal combustion engines comprises a disc or shallow formed cup of perforated mesh attached to the fan hub or fan shaft just upstream of the radiator and fan. Rotating at fan speed dirt and debris collected by the disc is centrifugally ejected from the edge of the disc and thereby prevented from entering the air passages through the radiator. The centrifugal ejection also makes the disc substantially self-cleaning.
