This robust unit, identified by part number \u003cstrong\u003e5363-03F-12-004\u003c\/strong\u003e, is engineered to prevent corrosion, noise, and heat transfer degradation by effectively removing entrained air from heating and cooling loops.\u003c\/p\u003e\u003cp\u003eThe Rolairtrol utilizes a sophisticated, patented centrifugal action to force air bubbles out of the fluid stream. As fluid enters the separator, the internal design slows the velocity and creates a vortex, allowing air to rise and be collected for purging, while the de-aerated water continues through the distribution system.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Air Removal:\u003c\/strong\u003e Patented centrifugal technology ensures rapid and thorough separation of micro-bubbles from system fluid.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNoise Reduction:\u003c\/strong\u003e Effectively eliminates turbulent air pockets that contribute to cavitation and system-wide gurgling sounds.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Longevity:\u003c\/strong\u003e Minimizes oxygen-related corrosion and scale buildup, significantly extending the service life of pumps and heat exchangers.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for high-demand hydronic heating and chilled water systems where consistent fluid flow and maintenance of optimal thermal conductivity are mission-critical.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43136961019998,"sku":"RL-3FB","price":5070.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/RL_3FB_image_5ef72fe9-ced2-40b3-8767-6d1e98c6ea65.png?v=1786158185","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-rl-3fb-rolairtrol-air-separator-5363-03f-12-004","provider":"National Boiler Supply","version":"1.0","type":"link"}
