So is this a stupid idea, likely to get me killed, or a reasonable way to vent?
Currently working with a HVLP gun in a two car garage. I've also got a 1 1/2 HP Grizzly cyclone dust collector. I've been putting a 4" collecting duct right next to the project I'm currently working on.
Downsides:
1) Probably coating the inside of the flex tube, maybe cyclone
2) It's a bit awkward
3) Explosion? I don't think the motor of the DC is exposed to the inner workings of the cyclone chamber.
Pros:
1) DC moves ~1000 CFM, and vents to the outside. Currently no other outside ventalation, building is well sealed.
2) Duct is 20' of 4" flex tube, so I can put it very close to the project being sprayed.
This doesn't seem much more dangerous than your typical DIY paint booth with cheap box fan. Thoughts?
