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.

Abstract: A frame, a system and/or a method deploys a compact skid. The compact skid has a storage position and an operational position. The compact skid has an inner shell, an outer shell and a bladder. In the storage position, the inner shell is positioned within the volume of the outer shell. To expand the compact skid from the storage position to the operational position, an air compressor is connected to the bladder. The bladder is inflated to lift the inner shell vertically. When the inner shell is lifted, the inner shell is locked into place to the outer shell. The bladder is then partially deflated, and the air compressor is disconnected.
