Brock Super-Air®

Brock’s positive pressure Super-Air® Pneumatic Grain System can assist you in:
  • Moving grain from the dryer to multiple bins with the use of one power source.
  • Making conveying turns or corners without the use of additional auger systems.
  • Adding a simplified conveying system to new or existing grain handling systems.

Unlike other pneumatic grain conveyors, Brock’s SUPER-AIR Blower and Airlock Packages arrive at your site fully assembled, factory-tested and ready to install.


Vari-Able Speed Grain Conveying Systems


Our system adjusts speed according to air pressure. When more corn is in the system, air pressure elevates; when less corn in the system, the air pressure lowers. Our system auto-corrects. This means, as air pressure increases or decreases, our system automatically makes the PSI/speed changes. Once the system is up and running, you do not have to adjust any settings.

Tri-Lobe Blower

Our Tri-Lobe Blower features three lobes per shaft versus twin lobe, which has two lobes per shaft. A tri-lobe blower system will run at a lower RPM than that of a twin lobe system. Lower RPM gives you considerably less audible noise, along with smoother air delivery, and increased lifetime on all the mechanical components inside the blower unit.
