Why Automatic Air Venting Matters
Trapped air in hydronic systems reduces heat transfer efficiency, causes pump cavitation, and leads to annoying gurgling or banging noises. The Trane VNT0146 Automatic Air Vent Valve provides a simple, maintenance-friendly solution by continuously releasing entrained air at high points in the system — keeping your hydronic loop running quietly and at peak performance.
