Screen Selection

How to Select the Right Slot Aperture for Your Application

Slot aperture is the single most critical specification in a wedge wire screen. Too narrow and throughput drops. Too wide and target particles pass through. This guide covers how to determine the right slot size based on your particle distribution, flow requirements, and operating conditions.
