Flo Magnet
Rare earth magnetic separator Greenwood Flo-mag Magnet

The Greenwood Flo-mag is a rare earth magnetic separator similar to the Magnetic Grid Boxes but designed for smaller pneumatic lines. The sealed removable drawer has an offset double row of high intensity rare earth magnetic tubes with easy-clean facility.

Simply release the stainless steel catches, which are lockable and adjustable, and remove the drawer. By undoing the front T knob, the inner magnetic tubes are released, causing the metal contamination to fall off into a waste receptacle. The magnetic tubes are so powerful that they will extract ferrous and stainless steel particles at speeds of more than 20m/s.

Ideal for free flowing powders and granulates, it can be incorporated into either blown or vacuum lines, such as flour, sugar, salt, plastics recycling….
This type of separator can be offered as a viable alternative to the bullet magnet, with the added advantage of the easy-clean facility. Furthermore it actively improves safety with regards to ATEX/DSEAR regulations by effectively reducing spark risk in the process line.

Designed and manufactured for a global leader on pharmaceuticals: 75mm line, fully welded, mirror finished, passivated.
