Improving hydronic system performance, this DISCAL air separator removes micro-bubbles and trapped air using proven low-velocity separation technology. The rotating collar union design simplifies installation and alignment on 1" MNPT connections. By eliminating air pockets, the separator reduces noise, improves heat transfer, and protects system components from corrosion. Ideal for radiant, boiler, and closed-loop heating systems.
