Astec Vari-Frequency™ Screens use a patented deck design to reduce blinding and improve screening efficiency. The Vari-Frequency bottom deck works with the screen’s natural vibration to stimulate the media and material, helping maintain production in demanding applications. Built on Astec’s LP Horizontal Screen platform, the design combines adjustable oval stroke motion, low overall height, and durable construction. The system can be adjusted for different screening requirements by changing stroke angle, stroke length, and operating speed.

Key Features

• Vari-Frequency bottom deck improves screening performance and throughput.
• Adjustable oval stroke adapts to different screening applications.
• Low profile design improves portability and installation flexibility.
• Huck bolted construction provides durable, low-maintenance operation.
