Wells waste oil filter. This is a tall red barrel with 3 hand-grips on each side. There are black concentric rings around the barrel and a spout about one-third way from the top. There is a lid with a handle on top. The dirty oil is siphoned from the top chamber and passes through 2 filters. The clean oil is then drawn off from the bottom chamber. There is a brass tap at the bottom to draw out the oil.
