Grain air pre-cleaner
Ensure the purity of your grain products by effectively removing dust and light particles, reducing contamination risks, and optimizing downstream processing with automated air cleaning technology.

Removes Dust and Light Particles from Grains
The ASU and ASA Air Cleaners from Bühler Group are designed for effective dust and particle removal in grain and food processing industries. These systems are engineered to mitigate dust explosion risks and optimize equipment efficiency through their precise air cleaning capabilities. The ASU model, utilizing a recirculation system, minimizes filter surface and space requirements, while the ASA operates on exhaust air, ideal for dustier environments. Their compact design allows seamless integration into existing processes, handling diverse food products such as corn, malt, and grains, and maintaining production throughput with high cleaning precision. With discharge screws to prevent filter clogging, these air cleaners ensure prolonged service life and reduced maintenance needs. Additionally, the equipment supports continuous, automated operation with optional wear protection for abrasive applications, enhancing durability and reducing costs for producers. Suitable for use in grain processing, animal feed, and agricultural cooperatives, these systems are essential for maintaining cleanliness and safety in production environments.
