Designed as a high-performance centrifugal air separator, this unit (\u003cstrong\u003e5363-05F-12-004\u003c\/strong\u003e) is engineered to separate entrained air from system water, ensuring silent operation and preventing the internal corrosion caused by oxidative buildup in hydronic loops.\u003c\/p\u003e\u003cp\u003eThe Rolairtrol system utilizes an internal centrifugal design to create a vortex, forcing air bubbles to the top where they are collected and vented. This patented flow pattern maximizes air removal capacity across various flow rates, making it an essential component for system longevity and effective heat transfer.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentrifugal Separation:\u003c\/strong\u003e Advanced internal design forces air bubbles toward the high-point air vent.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Protection:\u003c\/strong\u003e Reduces the risk of pump cavitation and accelerated pipe corrosion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance Efficiency:\u003c\/strong\u003e Dramatically minimizes the need for manual bleeding and system venting.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial hydronic heating and cooling circuits, large-scale radiant floor systems, and multi-zone HVAC applications requiring consistent air removal for reliable system performance.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43136961577054,"sku":"RL-5FB","price":5997.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/RL_5FB_image_7ebe1665-1d8f-47c7-9ca1-929fd975cdee.png?v=1786158384","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-rl-5fb-rolairtrol-flanged-air-separator","provider":"National Boiler Supply","version":"1.0","type":"link"}
