• Anti-rotation/anti-vibration pinned float creates space between float and air vent wall to prevent float hang-up from debris or variations in separator installation orientation Anti-corrosion coalescing mesh constructed of glass filled nylon More resistant to dissolved oxygen and acidic fluids than plated metals Corrosion-resistant all components highly-resistant to hydronic chemical additives or unstable pH fluid Large diameter chamber slows fluid flow dramatically Combines with concentric, sharp edged mesh design to cause micro-bubbles to efficiently collect and coalesce Highly effective automatic air elimination Robust stainless steel float linkages reliable float alignment even during turbulent conditions such as filling from bottom
