Pore geometry optimizes these filter meshes’ flow capacity

This company’s Optimized Dutch Weave (ODW) line of filter meshes (photo) has recently been updated to enhance flow capacity. The flow-optimized ODW meshes boast a specific mesh construction that allows for a pressure–loss coefficient that is reportedly 8.5 times lower than competitive products in the market. A special weave creates a slot-shaped pore geometry on the mesh surface, where the openings are smaller than the pores inside the mesh. ODW meshes are used where precise filtration rates are required that involve high flowrates and dirt-holding capacities, and are especially suitable for use in filter cartridges and filter discs for high-viscosity media, such as oils and polymers. ODW meshes also have a very low tendency to clog and a long service life, according to the manufacturer. Optimized cleaning properties make the meshes appropriate for backflushable filters and rotating-disc filters for solid-liquid filtration. — GKD-USA, Inc., Cambridge, Md.
