The Caleffi Discal 551007A 3-Inch Flanged Air Separator is a high-capacity, commercial-grade hydronic component engineered to continuously extract entrained air and micro-bubbles from primary chilled water and closed-loop hydronic heating distribution systems. 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.
Advanced Coalescing Media Design
Unlike 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.
Heavy Commercial Facility Benefits
- Automatic High-Capacity Air Vent: Outfitted with an integrated top-mounted automatic air vent assembly that manages high-volume air pockets safely without manual bleeding cycles.
- ASME Section VIII Construction: Constructed from thick structural carbon steel that meets strict building codes and municipal engineering standards for pressurized institutional installations.
- Low Pressure Drop Geometry: Engineered with an expanded inner chamber body that maintains smooth volumetric flow velocities, minimizing energy-sapping system pressure drops.
