Aeration Fans

Aeration fans

More air, less maintenance

S3 Air Systems offers a wide range of high-efficiency aeration fans designed to deliver maximum airflow for grain storage. Built with durable steel bodies and powder-coated steel inlets and screens, our fans are built for long-lasting performance in tough agricultural environments.

Strong, lightweight fan components, including rust-proof aluminum rotor assemblies, ensure ultra-smooth, quiet operation with reduced vibration. The result? Faster run-up times, lower amp draw, and more consistent air delivery for even temperature and moisture control in grain bins and silos of all sizes.

Designed for easy installation, our fans feature larger starter boxes and are Bin-Sense® controller ready, making integration into your existing aeration system seamless. All S3 Air Systems aeration fans are CSA-approved and backed by our SWOP warranty program. Our commitment to high inventory volume ensures lightning-fast order fulfillment and warranty response times.
