Capacity, base, cone angle and existing ducting determine what needs checking first.
Silo Aeration
Silo Aeration Systems for Grain Condition
We quote and supply silo aeration fans, kits, controllers and accessories across QLD and Northern NSW, with product support afterwards.
Why it matters
Grain left without airflow doesn't just heat up. It loses value.
In Queensland's climate, stored grain is vulnerable to heat, moisture, and insects from the day it goes in. Moving cool, dry air through the stack is the most effective way to hold quality and grade through the season.

Most in-store grain loss is preventable.
Heat, moisture migration, and insects are the main drivers of in-store grain loss, and correctly sized aeration addresses all three.

Common questions
Silo Aeration — your questions answered
Straight answers first, with the product fit, supply path and site details confirmed before quoting.
Send a questionHow do I know what size fan my silo needs?
It comes down to your silo's volume and the airflow needed to cool the grain. Tell us your silo sizes and we'll work out the right fan, not undersized, not overspec.
Can you fit aeration to silos I already own?
Usually, yes. We retrofit aeration to most existing silos, conical, flat-bottom, and poly, once we've checked the base type and cone angle.
Do I really need a controller?
Not always, but it often pays off. A controller runs your fans only when the outside air will actually cool and dry the grain, which saves power and protects quality. We'll tell you honestly if it's worth it for your operation.
