Abstract
An apparatus and a method filters particles using a screen assembly with an inner section, an outer section and a screen material. The inner section and the outer section form an opening. The screen material is stretched across the opening and is supported by the inner section. The inner section is flexible relative to the outer section. When particles are introduced to the screen material, the inner section flexes to reduce strain on the screen material.
