A vacuum box below the polyester filter belt that is mounted along the filter and collects the filtrate through a manifold to the receivers. The box at its topside has two lips covered with low friction synthetic strip liners that seal through intermediate wear belts between the bottom side of the belt and the surface of the strips.

Since the polyester mesh fabric  is the most expensive part of the filter these endless narrow belts serve as a sacrificial component that takes the wear between the surfaces, protects the rubber belt and secures against vacuum leaks.

A special mechanism allows parallel lowering or swinging of the vacuum box for cleaning from fines that may have settled inside. The mechanism is designed to accurately seal between the underside of the main polyester filter belt and the two narrow wear belts that move together along the slide strips attached to the top shoulders of the vacuum box.
