## Questions & Answers

**Q: Bought 12” for 12” flange and ceiling box… it is extremely tight and doesn’t seem to want to go on the flange or box? Am I missing something?**
A: It is a tight fit I used it on mobile home went on fairly easy they do mention in the description it is used for mobile home so I'm not sure if it works on your application or not Hope this helps

**Q: can this be made explosion proof with wire clips? planning to use as vent for paint spray booth using flammable paints**
A: This is where you get professional advice.  Also don’t “roll you own” when it comes to explosion proof stuff.  There are companies out there that make explosion proof stuff as well as paint booths.  Their are various UL and NFPA requirements that have to be met.  Look for used equipment, with this economy it is out there. There are ways of saving money, there are parts of this you can DIY, but you need someone who understands the hazards to do this safely.   Also, anyone telling you how to do this without seeing what you want to do - does not know what they are doing.

**Q: Im making  my own welding extractor, do you think that is going  to work?**
A: Yes, it should work for a welding extractor. Use duct tape between the ducting and the metal clamps to protect the ducting, otherwise the clamps can rip holes in it

**Q: Can this  replace hvac duct work for a house**
A: It will but I'd advise not to. It's not insulated enough.

### ⭐⭐⭐⭐ Review
*by D***A on 21 February 2023*

I bought a whole house fan from Lowe's, the advanced kind with a grill attached to the ceiling connected to about 6 feet of flex duct, with the motor at the other end, which draws hot air out of the house and puts it in the attic where it is expelled outside via various vents. Works great in our house, but I did a variation for the one I just bought for the garage. I, being a lifelong metal man with 20 years in ductwork, used my know how to build a plenum box and stub out 3 intakes, each 12 inch round, and instead of using the grill provided with the fan, I attached flanged box to my plenum, and ran this 12 inch flex out to a box I made for each of 3 rooms. I had grills already laying around, and made the flange to fit each grill. I put volume dampers in the 2 shorter runs to balance the intake volume if necessary. The ceiling is 11' 5",, and this the reason I "zoned" the garage, shop and rec room- one intake would not adequately pull heat out of the other 2 ceilings. Now, some tips. I made my collars 11 7/8" outside, and I still fought each connection. You could make your collars 11 3/4" and you wouldn't regret it. The reason I gave 4 stars is the material will tear if it encounters a sharp edge, like the overlap, or a burr on the edge. I recommend you have some silver tape handy and tape over the overlap and file any burrs on the outside edge. Crimping the edge will cause the same problem, so I don't recommend you hand crimp or buy start collars that come pre crimped. The metal drawbands are decent, and phillips bit in a battery drill did the trick. When you go to fit the flex on your start collar turn the excess fabric back (like you were trying to turn it inside out) to get it out of the way. It wouldn't hurt to tape metal to flex before you band it, I did. I use 3M x 3" wide. I cut my first run at about 20 feet, using wire cutters instead of snips. that left enough for my second run. I have one more to do, but I fired the fan up and it worked as expected. I'm sure I'll be pleased when the ceiling is installed. I hope these tips help you gitrdun.
