This robust component is essential for preventing corrosion, noise, and heat transfer degradation caused by air pockets in hydronic heating and cooling systems.\u003c\/p\u003e\u003cp\u003eThe unit utilizes a sophisticated patented centrifugal design to force air bubbles out of the fluid stream. As system fluid enters the separator, the internal velocity change and centrifugal force cause air to separate from the water, allowing it to be vented automatically through a connected air vent, ensuring only air-free fluid circulates back into the system.\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 geometry effectively strips micro-bubbles from the circulating fluid.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Mitigation:\u003c\/strong\u003e Reduces oxidative damage by removing the primary source of oxygen entering the piping loop.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Longevity:\u003c\/strong\u003e Prevents premature pump failure and noise by ensuring smooth, cavitation-free fluid circulation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy Maintenance:\u003c\/strong\u003e Simplified design allows for streamlined inspection and cleaning during routine system service.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial and industrial hydronic heating and cooling systems, high-rise buildings, and closed-loop process water cooling applications.\u003c\/p\u003e","brand":"Bell \u0026 Gossett","offers":[{"title":"Default Title","offer_id":43136961183838,"sku":"RL-3G","price":2961.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/RL_3G_image_79a78906-9e10-459d-88a7-57c7358a40c3.png?v=1786158224","url":"https:\/\/nationalboilersupply.com\/products\/bell-gossett-rl-3g-rolairtrol-air-separator-5363-03g-12-003","provider":"National Boiler Supply","version":"1.0","type":"link"}
