Magnetic Sheet Fanners

Bunting magnetic sheet fanners put an end to the inconvenience of manually prying apart sticky, oily polished or prefinished ferrous sheet stock. Magnetic sheet fanners utilize a constant, powerful magnetic force to automatically fan sheets apart with no risk of electrical hazards. Machine operators and robotic arms can reliably and safely remove one sheet at a time, eliminating the chance of “doubles” jamming or damaging your machinery. Bunting offers both standard and switchable varieties of sheet fanners. By using Bunting magnetic sheet fanners, you can improve both safety and efficiency in your facility.

Separate Stacked Ferrous Sheets with Permanent Magnetic Power. Put an end to manually prying apart oily, sticky, polished or prefinished ferrous sheets. Bunting® Permanent Magnetic Sheet Fanners are a faster, safer alternative for handling stacks of sheet stock. They provide a constant, powerful magnetic force that automatically fans sheets apart – without the risk of electrical hazards. An electromagnetic field automatically separates the sheets.

An electromagnetic field automatically separates the sheets. As fast as the top sheet is removed, the next sheet instantly moves up and is ready to be handled. Machine operators and robotic arms can reliably and safely remove one sheet at a time, eliminating the chance of “doubles” jamming or damaging your machinery.

Inside their rugged, stainless steel housings, Bunting® Sheet Fanners use high-energy permanent magnets to separate stacks by inducing like polarities in adjacent sheets, causing magnetic repulsion between them. This repulsion fans the sheets apart. When the top sheet is removed, the next sheet rises to take its place. The distance between the top two sheets will average between 3/4” to 1 1/4”, depending on the magnetic strength of the Fanner and the size of the sheets. Fanners can be ganged to handle especially large or heavy-gauge sheets.

Standard Sheet Fanners are completely self-contained and come with both predrilled mounting holes for permanent installation and carrying handles for moving between workstations. They are available in two standard face widths and can be stacked one above the other or mounted side-by-side to accommodate a wide range of stack and sheet sizes.

Bunting® Switchable Sheet Fanners are available in Generation I and Generation II models, both of which can be “turned off” to avoid accidents while being resupplied with sheets. Both models are patented (U.S. Patent No. 6,481,706) and outfitted with powerful Rare Earth magnets for outstanding separation performance. Both feature reliable pneumatic mechanisms to turn the magnetic field on and off.

Generation I Switchable Sheet Fanners use a pneumatic rotary actuator to control the fanning action by rotating a single-pole Rare Earth magnetic element, which is mounted near the center of the housing. Generation I Switchable Fanners are a compact 4” wide to fit tight spaces and handle lighter loads.


Generation II Switchable Sheet Fanners have a 7” wide face plate and produce a stronger fanning action suited to larger blanks and thicker gauge steel. They use a conventional pneumatic cylinder to rotate a two-pole Rare Earth magnetic element mounted at a pivot point set close to the side of the housing. With this side-pivot geometry, rotating the magnet just 90 degrees faces it toward a built-in shorting circuit to cancel the external field.

Drive Rollers move and control sheet stock ranging from .010 inch thin plate sheets to over .250 inch thick. Bunting’s exclusive design is engineered for trouble-free, efficient handling of sheet stock.
