The rotation of the water/air mixture provides a long contact time with the pollutants resulting in a highly efficient performance. The extremely fine water/air mixture is pumped into the contact tube, where it rises and is collected in a removable cup at the top of the skimmer. When a skimmer is running it will produce a head of foam which is determined by the amount of air and the bubble size. A simple general way of comparing the relative performance of a skimmer without even running it is to look at the neck diameter where it enters the cup. The larger this is, the greater the performance, as it takes a greater head of foam to be able to climb up a larger diameter tube. The diameter of the AP1006 riser tube&nbsp;is 8&quot;. Compare that with your existing skimmer and you will understand what we are talking about. Tapered tubes simply reduce the opening to cope with a smaller volume of foam.
