Dose the foam extractor mechanically pull the foam/skimmate or does it use gravity to just allow the foam to continue along the tube?
It's gravity fed. The dry foam collects at the top of the extractor and is blown into the large diameter (40mm) tube where it falls to the collection container. It also reduces the diameter of the skimmer. The collection cup is a tight squeeze in the Cadlights sump. Removing the cup and replacing it with the foam extractor frees up a lot of space and increases the overall size of the reaction chamber allowing you to draw more air while still collecting drier foam.
