Instructions for installation of slip duct
The chart below allows you to choose the correct duct size for the air volume that is required. Different materials need to be conveyed at different velocities to prevent the material from falling out of the air stream. For example, wood chips and saw dust flow well between 18 and 22 m/s.
Referring to the chart, a 100mm duct will convey 622 m³/h at 22 m/s. This indicates that a 100 mm pick-up on a machine will use 622 m³/h from the filtering system. Or working in reverse, if you know that a machine will require approximately 650 m³/h to remove the waste, then you should design a 100 mm duct for the application.
