High-pressure centrifugal fans ideal for temporary wet grain holding, deep storage, and facilities where high static pressures are required. Direct drive, rugged steel housings, and vibration-proof fan wheels.
Engineered for efficient, high-volume air delivery where storage depth is low to medium. Axial airfoil propellers are statically and dynamically balanced and secured to the motor shaft with a self-locking mechanism.
Introducing the revolutionary Retro Rocket, the only do-it-yourself rocket system that allows you to retrofit existing hopper bottom and smooth-walled bins with farm proven Grain Guard aeration.
Ideal for conditioning and cooling grain. The new design includes laser-cut internal rings providing increased strength, as well as downward facing louvers that provide improved cleanout.
Designed for maximum airflow. The Helfer duct rocket penetrates the center of the bin to release air into the core, fan efficiency is increased by as much as 20%, and Static pressure is lowered.
Systems can be run in a straight line down the center, or can be designed to serve your specific needs. Systems can be custom-designed to your building size and the product to be aerated.
