Abstract (en)
[origin: WO2018191611A1] A screen filter having a plurality of support rods arranged in longitudinal relationship such that a continuous length of wire can be spirally wrapped about the support rods to define a cylindrical body. Along the length of the cylindrical body, slots are defined between adjacent wires wherein each slot has a slot width that determines an overall filter performance for the screen filter. The screen filter is fabricated such that an average slot width across the length of the cylindrical body is equal to a filter performance rating. The screen filter is fabricated such that the slot width for the cylindrical body has a normal distribution wherein 99.7% of the slot widths are within three standard deviations of the average slot width.
