General Description
The AGI Retro Rocket is an excellent addition to any new or existing hopper bottom bin that does not
presently include an aeration system. It can allow you to harvest in damp conditions, maintain stored
grain in peak condition, and reduce the likelihood of mould growth and insect infestations.
Key features of AGI Retro Rocket:
• Fits through existing bin openings that are at least 19” square, 22” diameter, or 18.5” x 16” oval
openings
• Reduces grain drying time and increase fan efficiency by directing air into the core of the bin.
• Unique folding design allows it to be installed through an opening much smaller than itself.
• Inserts through smaller openings that are at least 16” round or 12” square by removing four bolts
and inserting the rocket in sections.
• Can be assembled and unfolded into working position once inside the bin.
With proper care during and after installation, your aeration system will provide you with many years
of trouble-free service.
Intended Use
The rocket is intended for use as listed below and described throughout this manual. Use in any other
way is considered contrary to the intended use and is not covered by the warranty.
The Retro Rocket may be safely used with grains of all types, do not use with fertilizer.
