Built with a heavy-duty brass housing, this unit provides exceptional durability and outstanding resistance to demanding system environments. Its low-maintenance, high-performance architecture makes it an ideal solution for hydronic heating and cooling configurations.\n  \u003c\/p\u003e\n  \u003cp style=\"margin-top: 15px;\"\u003e\n    Engineered to continuously clear entrained micro-bubbles down to a macroscopic level, the DISCAL 551 series purges accumulated system air with minimal head loss across the circuit layout. Inside the primary chamber, an advanced glass-reinforced nylon internal element coalescing assembly slows internal flow velocity, forcing hidden micro-bubbles to aggregate, float upward, and automatically escape via its high-capacity automatic atmospheric air vent structure. This full de-aeration cycle dramatically mitigates ongoing line chatter noise, stops oxygen-driven localized pipe corrosion, eliminates cavitation damage inside commercial circulator assemblies, and lowers recurring call-backs.\n  \u003c\/p\u003e\n\u003c\/div\u003e","brand":"Caleffi","offers":[{"title":"Default Title","offer_id":42913135722590,"sku":"1110","price":240.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/Caleffi_Discal_1.25_NPT_High-Efficiency_Air_Separator_heavy-duty_commercial_hydronic_system_component..webp?v=1782009657","url":"https:\/\/nationalboilersupply.com\/products\/caleffi-551007a","provider":"National Boiler Supply","version":"1.0","type":"link"}
