This high-performance component, known as the \u003cstrong\u003eVAS-4\u003c\/strong\u003e, is engineered to reliably eliminate trapped air, preventing noise, corrosion, and heat transfer inefficiencies that can compromise system longevity.\u003c\/p\u003e\u003cp\u003eThe unit utilizes a specialized vortex or whirlpool action that forces heavier, air-free water toward the outer tank perimeter. Simultaneously, the lighter, air-entrained water mixture is channeled into the lower-velocity center, where air is efficiently separated and vented from the fluid stream.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVortex Separation:\u003c\/strong\u003e Advanced centrifugal action for superior air removal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem Protection:\u003c\/strong\u003e Reduces the risk of cavitation and corrosion-related component failure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePerformance Optimization:\u003c\/strong\u003e Enhances thermal conductivity by maintaining air-free fluid circulation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Design:\u003c\/strong\u003e Robust construction built for long-term hydronic system reliability.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial hydronic heating systems, chilled water loops, and large-scale residential boiler installations requiring consistent air management.\u003c\/p\u003e","brand":"Armstrong","offers":[{"title":"Default Title","offer_id":43137057652830,"sku":"VAS-4","price":4500.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/VAS_4_image_49792af3-d0b1-4983-8174-ef4012093ee2.png?v=1786165845","url":"https:\/\/nationalboilersupply.com\/products\/armstrong-574116-033-vas-4-vortex-air-separator","provider":"National Boiler Supply","version":"1.0","type":"link"}
