Hi,
I have an inline fan that is being used for dust extraction. The fan is 1200mm wide with a 55kW motor (1400rpm). There is a cone/hood on the inlet side of the fan that is around 1m long and is slightly larger than the diameter of the fan (not sure exactly how much larger, around 400mm diameter overall I'm guessing). On the outlet side of the fan there is square ductwork that is 1400x1400mm that goes around 30m into a dust extractor.
The issue we are having is that at the inlet of the fan there is air blowing back out of the inlet the wrong way. It is happening around the outside edges of the hood. It isn't much air, but it is disturbing the dust in the room that has fallen to the ground and is actually making the entire situation worse.
I'm just a lowly electrical engineer and so I really need a bit of help with this one!
One last thing - if we open up the dust extractor hatches and remove the socks the blow back seems to improve.
Thanks
