Astec Vari-Frequency Screen: Redefining Screening Efficiency

The Astec Vari-Frequency Screen introduces a breakthrough approach to minimizing blinding and boosting productivity. Positioned on the bottom deck of a horizontal screen, this patented technology harnesses natural operational frequencies to stimulate the screen media, keeping material moving and reducing buildup. Designed for use with standard wire cloth and requiring no external power source, it delivers higher throughput, greater efficiency, and lower operating costs. Its low-profile design fits height‑restricted setups while simplifying maintenance and maximizing uptime. Built for demanding applications, the Vari-Frequency Screen helps producers spend less time cleaning — and more time producing.
