Patent ID: 8201495

Claim:
A separator system comprising: a housing assembly defining a housing chamber, an inlet, a first outlet, a second outlet, and a housing axis; a screen member, where the screen member is arranged within the housing chamber to define a pre-separation portion of the housing chamber, the screen member is symmetrical about the housing axis, and the wall of the screen member is angled with respect to the housing axis; a wiper assembly arranged within the pre-separation portion of the housing chamber, where the wiper assembly defines at least one edge surface, and the at least one edge surface is substantially parallel to the wall of the screen member; a drive assembly supported by the housing assembly; a coupler assembly for operably connecting the drive assembly to the wiper assembly; whereby operation of the drive assembly causes rotation of the wiper assembly about the housing axis such that the at least one edge surface of the wiper assembly moves relative to the wall of the screen member; and as the at least one edge surface of the wiper assembly moves relative to the wall of the screen member, the coupler assembly allows gravity to maintain the at least one edge surface in contact with the wall of the screen member.
