Woodworking dust removal centrifugal or axial flow of good?
Axial fan has large air flow, but most of the axial fan pressure will not exceed 600Pa.
Because dust woodworking equipment is needed in connection with the pipe, dust collector, dust containing air travel in the pipe and pipe wall friction resistance, and the dust collector structure will also have 500-800Pa resistance, so in order to overcome this resistance, requires the fan to generate sufficient pressure to overcome the resistance that is to ensure the absolute flow pressure means.
Use centrifugal fan, no second.
