Vari-Frequency™ Screen
Screening Redefined for Maximum Efficiency. The Astec Vari-Frequency Screen represents the next evolution in advanced blinding minimization.
Overview
Screening Redefined for Maximum Efficiency
The Astec Vari-Frequency Screen represents the next evolution in advanced blinding minimization. The patented deck design harnesses natural frequencies and vibrations during operation, which stimulate the screen media and bulk material, effectively reducing blinding and boosting productivity. The result is higher throughput, greater efficiency, and lower operating costs.
Built for standard wire cloth and with no external power source required, this Vari-Frequency technology is adaptable and easy to maintain. It performs reliably across a wide range of applications and is engineered to excel in demanding material conditions. Spend less time cleaning and more time producing with screening redefined by Astec.
