this is probably a stupid question, but I have to ask it. why do I want to collect saw dust?
I have a small woodworking shop with bandsaw, table saw, jointer, shaper drill press and radial arm saw in a building separate from my house. I don’t use it very often just when I need something. I have always just swept up the saw dust every month or so when it got too deep. I have a small dust collection system tied to my radial arm saw which I use most. usually when I am using the table sander I just open the double doors and turn on the big fan. I don’t care about heating or cooling the shop.
My question is, since I have so many tools to connect, can I buy 4” flex pipe at the hardware store and connect to table saw and other tools and then a add a blower SUNCOURT Inductor In-Line Duct Fan 6-in Dia Galvanized Steel Axial Duct Fan in the pipe and suck up the dust and blow it outside? not collect the dust just watch it blow into the yard
or will the fan die real fast?

thanks for the feedback

The sawdust and chips will destroy the motor on a duct fan. Use a dust collection blower where the dust will not get in the motor. Such as…. http://www.harborfreight.com/13-gallon-industrial-portable-dust-collector-31810.html , just don’t use the bag filter.

that is basically what we used to call a squirrel cage fan, I think? if I have an old one that was used in a ventilation system would that work?

A squirrel cage fan won’t work. That type of fan doesn’t develop enough static pressure for exhaust service; it is mean’t for blowing, not sucking.

you have saved me a lot of trouble, thank you.
since I dont plan to use the bag would I be better off to try and buy a fan someowhere else with similar specs to the one from harborfreight or should I go ahead and buy from them?
I have never felt very good about the quality I received from HF

If you don’t want to spend a lot I think the HF one I linked to is your best option. Other similar ones are quite a bit more expensive.

Have your say...
