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.\u003c\/p\u003e\n\u003cp data-start=\"2021\" data-end=\"2531\"\u003eIn D.E. filter equipment, internal manifold components are critical to maintaining organized flow through the grids and preserving the overall function of the assembly. When the original manifold becomes worn, cracked, or otherwise compromised, replacing it can help restore the filter to proper operating condition. This part is well suited for pool owners, service technicians, and maintenance professionals performing internal filter repairs, rebuilds, or scheduled service on compatible FNS Plus equipment.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48995026469176,"sku":"59023700","price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0808\/6319\/9544\/files\/PEN59023700_0.jpg?v=1720613795","url":"https:\/\/appaetechpoolsupply.com\/products\/pentairmanifoldtopwairbleed59023700","provider":"AquaTech Pools \u0026 Spa","version":"1.0","type":"link"}
