Tilt angle is the specific angle between surfaces of each V-profiles. Since the angles create a gap to intake water, it directly affects the capacity of the flow and particle sizes to be prevented. This angle creates shearing offsets into the flow above the screen and this provides high filtration and smooth intake for the Coanda Intake Screen. Most common tilt angles are between 3° – 5° which affects the capacity and maximum allowed particle size for the filtration. For more information, check our website: http://coandaintakes.com/
