SpiroTop automatic air vents should be mounted at any point in an installation where air can gather and in places where air pockets are present. The SpiroTop should be installed vertically, with the connection at the bottom.
Note: an automatic air vent only removes free-circulating air. To deaerate an installation actively and also remove micro-bubbles and dissolved air, a deaerator or vacuum degasser should also be installed, depending on the type of installation.
SpiroVent deaerators should preferably be installed at the hottest point of the installation. In a heating system this is directly behind the boiler. In a cooling system the air separator should be installed in the main return pipe.
Installation in front of the pump prevents accumulation of micro-bubbles around the pump shaft. Air around the pump shaft can significantly reduce the lift of a pump.
As dirt particles are always present in the main flow and are difficult to divert to a bypass pipe, a SpiroTrap dirt separator must always be mounted in the main pipe. For both heating and cooling systems the main return pipe is the best position.
Under normal circumstances a SpiroTrap dirt separator cannot become blocked, as all the dirt is removed from the stream and collected. As a result the collected dirt will not cause an increased pressure drop or flow resistance.
A SpiroTop automatic air vent or a SpiroVent does not require any maintenance. After initial draining upon delivery of an installation, a SpiroTrap dirt separator only requires opening for a few seconds every now and then. This is normally done during regular maintenance on the installation.
