Product Overview

The Pentair 59023700 Top Manifold with Air Bleed is an internal replacement part used in compatible FNS Plus diatomaceous earth filter systems. Installed in the upper section of the filter assembly, the manifold helps route water through the internal grid structure while the air bleed feature assists with releasing trapped air from the system. These functions are important for proper startup, balanced circulation, and dependable filtration performance.
