AFT provides a variety of slotted plates, mainly used for filtering applications such as extraction towers. Generally a slotted plate will be flat and precision cut. Plates can be manufactured in a variety of metallurgies as needed for a given application. In some cases plates are bent, while slot tolerances are still maintained. This type of manufacturing process can be expensive relative to a wedgewire or plastic design, and is generally used when an exact slot width is needed or a special metal is required for an application. Another advantage for a slotted plate is that it can be made in a variety of thicknesses to meet strength requirements.
