Permanent Magnet Sheet Fanners with Air Knives allow for ferrous and non-ferrous sheets to be separated in stacking and destacking applications. While the magnet force will work with all ferrous metals, the air knives separate all non-ferrous metal by pushing air in between the sheets causing them to rise up from one another.
Air Spring Fanners have an air spring system that pushes the magnet inside toward the face of the fanner when air pressure is present. When the air pressure is turned off or disconnected the air spring will deflate and the magnet will move away from the face of the fanner creating air gap that in essence turns the magnet off.
Electromagnetic Sheet Fanners eliminate die-damaging, double-blanking problems in automated sheet handling operations. A powerful electromagnetic field automatically separates the sheets. As fast as the top sheet is removed, the next sheet instantly moves up.
