I have several plans to improve dust collection in my garage workshop. The three projects to accomplish these plans are to build my own air filter to remove small particles trapped in the air, to renovate my dust collector cart to double as storage and be more stable/sturdy while incorporating a better chip-separator, and to create a contraption of some type to attach a dust deputy to my shop vac without the unit being too large.
There will be 3 main challenges:
1) I’m still working on my overall shop renovation
2) I’m on a strict budget (I know I’m not alone here)
3) I’ve started another project with some self imposed deadlines (step stools)
The first project I plan to attack is the air filter. Our HVAC system recently failed us and we opted to replace the entire system. I had no idea how expensive a replacement was before I started shopping around. It will be nice in 7 yrs when the energy savings reach a break even point, but until then…. By my estimate, the replacement is 85% complete and the last steps will be done when the newly installed gas line has passed inspection.
I have already managed to salvage a free blower unit from the old system! I’ll admit, this is probably the most expensive free thing I’ve ever gotten, but I think it is a nice opportunity to save a few dollars compared to a manufactured unit and I can choose whatever type of filter setup I want, maybe even utilize filters that have already been used once inside the house, although I’m not sure of that.
When I went outside to look at the blower the workers were kind enough to detach and save for me, I was a little surprised by what I saw. There are 3 cut wires; Red, black, and white and all are only 18 ga. My understanding is that this is a 240 volt unit. I assumed that the red and black would be hot and the white would be neutral and as I’ve occasionally seen on 240V circuits, there would be no hookup for the ground (or maybe neutral doubles as the ground (I’ll have to research to refresh my memory). Does this sound reasonable to you guys that such thin wire can power such a strong fan? I was thinking I’d need a separate circuit for this item, but now I’m thinking it would be easy to run it off an existing 240V circuit.
Any feedback on this from someone with experience building their own unit or that has worked with HVAC systems? Just to clarify, I can’t read the wiring diagram. I’m going to try and clear the junk off, but I think it may dissolve, the paper label or remove the ink. It is a 20 yr old sticker.
