Base Assembly - Koblenz U75 / U80 513 it lets you match suctionDesigned for the Koblenz U75 and U80 uprights, this replacement base assembly (Part #13 2883 01 8, ref 7827) forms the lower housing that carries the nozzle and floor facing components.

Fitting a solid base restores the sealed airflow route so the machine draws dirt efficiently. Fits: Koblenz U75, U80 (ref 7827) Function: lower housing
