Brock’s SUPER-AIR Grain Cyclone

Brock’s SUPER-AIR Grain Cyclone offers the ability for high capacity grain handlingwith Super_AirGrainCyclone_03_a_1_the use of 4, 5, and 6 inch diameter systems and an appropriate adapter.  Plus, it provides gentler handling of grain than conventional “deadhead” collector units.

The Cyclone unit efficiently separates grain and air at the bin entry point with the grain dropping smoothly into the bin while the air is vented back into the atmosphere.  Cyclones come equipped with a replacement urethane liner to limit wear, and it’s manufactured from heavy-gauge steel with powder-coated paint for long-life durability.

  • A hand wheel is used to turn the inner spout to the desired conveyor line outlet.
  • The operator then uses the distributor handle to engage and lock the self-centering inner spout in place on the desired conveyor line outlet.
  • Brock’s SUPER-AIR® System is now ready to pneumatically convey grain to another bin or location in the storage complex.
