GF (downpipe)

For free falling powder and bulk products.


METAL SHARK® Gravity Feed (GF) Metal Detectors, available in both standard and compact models, are used in gravity feed pipelines to monitor for unwanted metal contaminants in continuous flowing granules or powders, such as sugar, flour, corn meal and spices. As bulk material flows through the metal detector, reject flaps promptly separate even the smallest metal contaminants from the product stream. Maintenance free design and high quality construction ensure reliable operation in the most challenging industrial environments. Pipe diameters are available from 3" to 24". Atex Zone 21 and 22 versions are available.
