Hello everyone,
I have a dust extractor of the centrifugual blower kind, which has a 1HP induction motor and 4" inlet port. Reading about the blower type of extractor, it seems larger diameter piping will give me much better flow as it gives less resistence. So I am considering 6" solid wall tubing to the workspace, perhaps with a reducer to a short section of flexible 4" hose I currently have. I am assuming with 8" or larger piping, the air will be moving so slowly that dust will build up in the pipework and eventually block it.
The inlet of the fan is a simple circular sheet metal piece with an extruded 4" tube, which would be easy to make in a larger/smaller size. I am wondering whether creating a 6" inlet and attaching that as the fan intake will be better than using a 6" to 4" reducer at the existing fan inlet.
The blades of the fan protrude slightly into the 4" circle when viewed straight on, and with a 6" port significantly more of the blade would be protruding, I wonder if this would mess up the suction in the centre.
Any thoughts?
