By purging air down to a microscopic level, this ultra-efficient inline separator eliminates system noises, protects high-end boiler heat exchangers from oxidation, and prevents devastating cavitation damage inside heavy circulation pumps.\u003c\/p\u003e\n\n\u003ch3\u003eAdvanced Coalescing Media Design\u003c\/h3\u003e\n\u003cp\u003eUnlike standard centrifugal or baffle-style air scoops, the Discal 3-Inch separator utilizes an internal matrix of multi-surfaced glass-reinforced nylon coalescing mesh elements. As air-saturated process fluid flows through the vessel, the stream is slowed down significantly, causing tiny suspended micro-bubbles to adhere to the media surfaces. These micro-bubbles naturally coalesce into larger air pockets that rise rapidly into the upper chamber, where they are automatically vented without fluid loss.\u003c\/p\u003e\n\n\u003ch3\u003eHeavy Commercial Facility Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutomatic High-Capacity Air Vent:\u003c\/strong\u003e Outfitted with an integrated top-mounted automatic air vent assembly that manages high-volume air pockets safely without manual bleeding cycles.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eASME Section VIII Construction:\u003c\/strong\u003e Constructed from thick structural carbon steel that meets strict building codes and municipal engineering standards for pressurized institutional installations.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLow Pressure Drop Geometry:\u003c\/strong\u003e Engineered with an expanded inner chamber body that maintains smooth volumetric flow velocities, minimizing energy-sapping system pressure drops.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eLooking for precise pressure drop curves or ASME flanged bolt pattern dimensions? \u003ca href=\"\/pages\/contact-us\" title=\"Request Official Caleffi Submittal\"\u003eClick here to request the official factory submittal manuals from our engineering desk.\u003c\/a\u003e\u003c\/em\u003e\u003c\/p\u003e","brand":"Caleffi","offers":[{"title":"Default Title","offer_id":42913098629214,"sku":"EXP-3INCH-1061","price":1299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/Caleffi_Discal_NA551080A_3_inch_flanged_air_separator_featuring_a_large_steel_cylindrical_body_finished_in_a_durable_green_epoxy_resin_coat_with_a_top-mounted_brass_air_vent..jpg?v=1782053106","url":"https:\/\/nationalboilersupply.com\/products\/caleffi-discal-3-inch","provider":"National Boiler Supply","version":"1.0","type":"link"}
