For application assistance, please contact Norgren Technical Support. In many cases, customers send product to Norgren to test at our in-house test facility.

Allow the compressed air powering the generator to assist in pushing the material to the collection hopper. Induced atmospheric air, compressed air and the material being transferred enter the collection hopper, where the material falls by gravity. The air vents out the top of the hopper. To capture lighter-than-air materials, connect a filter or dust collector to the hopper outlet. The NDF generator creates a vacuum in the collection hopper causing the material to flow up the conveyor tube into the collection hopper. Compressed air doesn't mix with the material, helping to prevent a cloud from forming when transferring fine, light powders. Material entering the hopper falls to the bottom faster due to the vacuum in the collection hopper. To reduce noise, add an optional silencer to the NDF generator exhaust. Hopper to Hopper Butterfly Extended Distance Transferring bulk and individual items vertically and horizontally over long distances may require a second conveying generator as a booster generator. To accept the flow generated by the first generator and to add power, add a booster generator that is larger than the first-stage generator. To maintain the proper balance between air intake and material intake use a valve to meter both. Transfering Bulk Materials: Caution When conveying materials through plastic transfer lines, you must ground the transfer line to dissipate the static charge that develops from the friction of the air and material flowing over the transfer line surface.
