my buddy does HVAC so i had him grab me a blower out of a furnace when 1 came around and it finally did so i came up with this simple design
my only real screwup was it was supposed to hang the other direction but i was running shy on plywood and for some assinine reason 18 inch joists popped into my head…even an idiot knows its 24 n being in construction for the past 13 years something should have popped in but it never did so yea not a huge deal but irks me..lol
as for pic #3 u can see the ply was supposed to be for something else but the size was right so i snagged it
the top (or bottom when hanging) is double hinged but has seal tape and 2 screws holding the big chunk closed so if need be i can get at the blower
i used an 800 for a pre-filter and 1500 for second filter
it definitely moves the air around the shop pretty good and as far as price goes 95% of the wood came from the left-overs of a cabinet i built for a buddy, the blower was free and the cord was laying around
the filters cost about 20-25 bux so it was a pretty cheap way to go and seems to do its job pretty well
right now i just plug it in and unplug it but it is a 4 speed blower so if i get a wild hair i may grab a remote ceiling fan controller and throw that in but for now it seems just fine
ill welcome any questions comments or insults ;)

hey big, just goto a HVAC place and talk to someone there, 99% of the time they replace a furnace the blower is not the problem, they will replace the blower but if they replace the furnace its usually the plenum or the heat exchanger is cracked and its basicly illegal ro run that way ;)

Nifty. I made one that uses three filters, two in front and one on exit. Works pretty well, just rotate the filters forward and toss out the dirtiest one.

It does make a difference if I’m running the ROS or router table.

I just got one of these blowers this past weekend that came from a 2 1/2 ton furnace. How did you wire it up? I’ve got a black, orange, and a red wire coming from the motor. Then there are 2 wires that looked like they were ran to the capacitor on top. Any advice for me on how to wire this guy up?

Here is a picture of the blower: http://www.hnwoodworks.com/storage/misc/photo.jpg

Hope to build a filter box this weekend.

Thanks for any advice!

a blower from a furnace is a good idea, and the remote is an even better idea, and it’s inexpensive. good job.

I cut a 5”X10” hole up high on the back wall of my shop and used a hinged plastic flap to cover it. Then I boxed in a similar blower unit with one filter in front of it and evacuate the air outside. The blower lifts the flap when I turn it on and it closes when as the fan shuts down. I change the filter about once every week or so. Those fan blowers do a fine job of making a shop a better place to work. They are an essential tool.

I gotta make one as I finish in the same space, damn that slow drying varnish! My Mom had a huge fan installed in the attic that cooled the house and one time they had a fancy dinner party for some out of town clients. Just before dinner, (all set on the table) she turned on the 3 HP fan and the doors were all closed so the only inlet was the fireplace! Ash came in and the whole house (and fancy dressed people) were covered with soot! Funny now but they had a lot of dry cleaning bills then.
