The closed loop piping network, such as that of chilled water system usually has an Air Separator in the Pump Room. Furthermore, Automatic Air Vents are provided at the highest points (Pipe Risers) to expel air before it even reaches the Air Separator. Sometimes the horizontal piping must be offset upwards to avoid other services and installations. Are Automatic Air Vents essential at these small (one foot high) offsets, or can the water push the air towards the Air Seperator (like it does in open to atmosphere systems such as domestic water supply)?
