Air release outlet in NOMINAL SIZE (large opening cross-section according to the flange size).
Flange according to EN 1092 (DN 50 also available with 2" threaded connection).
Efficient vacuum protection through high ventilation performance.
Optimal ventilation without early closure owing to very high air outlet speeds when filling the pipes or reservoir.
Effective protection against water hammers with high air release speeds thanks to the 2-stage ventilation system.
