Central Heating Air Separator Piping Diagram

An air separator is an in line device that removes entrained air microbubbles that is moving with the flow of the fluid.

Dirt separators if cleaned regularly have low pressure loss characteristics important for reducing energy demands and ongoing running costs. Excessive air within a system can cause excessive noise reduce the accuracy of control valves and the performance of heating and cooling equipment therefore removal is important. Air vents should be mounted at any point in a piping system where an air bubble could form. There are a few systems like this remaining in use but generally they are approaching 50 years of age or fitted by a diy installer with a very old book of how to fit central heating.

A new separator is about 20 so it might be worth installing a new one. So it is quite likely that the way it is currently installed is contributing to the pumping over.

Hydraulic separators must be properly sized to provide proper hydraulic air and dirt separation. Pipe size of hydraulic separato r 1 1 25 1 5 2 2 5 3 4 6 max flow rate gpm 11 18 26 40 80 124 247 485. The design of the air separator means that is has to be on its side with the side vent pipe at the top to work properly. They are different products for different purposes and you can t really compare efficiency between the two.

Excessively high flow rates will impede these functions.
