The OBM Hoover 700 is a air lift separator, designed for removal of paper, plastics and other light materials from compost, wood and other streams of heavy waste. The OBM Hoover 700 comes in a silent diesel and an electric model.
It works through a system of a heavy duty fan, air hose and funnel. The funnel is placed over the moving stream of waste (e.g.: conveyor belt), and filters lighter material such as paper.
The machine is standalone, placed on a frame with forklift lifting points which makes in easy to move around. A redesign in 2014 made the machine even more compact, making it possible to use even more easily.
