Ducting, wye's, 90's & blast gates
Its time yo get my cyclone working. i need to install the ducts, but have a few questions to make sure that I do it right. I am going with 6" PVC as I feel more comfortable with the stuff.
As my ceilings aren't massively hight, I have to run my ducts around the outside of the room and feed down to the machines. As I branch off for a machine with a wye fitting, does it make a difference how far the blast gate is from the main trunck? ie, will I get less loss if the blast gates are all coming off a wye split, or can I put the blast gate futher down the split off line to put it near to the machine that's connected?
I have read Bill's DC bible as some may call it, and gather that when turning corners, that sweeping arc's are better than sharp turns. Again, as space is not on my side, at what point is a sweeping arc good enough? Like you can get small 90s that turn the corner in under 4", and longer 90s that are 9". Or you can put 2x45s that are 20", or 4x22.5s that are 46".
I gather that 4" is rather bad, but would a 9" turn kill your air flow that much to be crippling?
What have others done and how does it work. I am installing a larger Clearvu Max (1800cfm) cyclone into a 18x17' double car garage. There is only the one of me so I'll be using one blast gate at a time. Will the unit just overcome what is thrown at it by brute force, or do I just give up aesthetics for pure function and how it looks be damned.
I got a quote from one supplier for the PVC pipe. Just want to run it by to see if it seems fair.
6" x 10' pvc sewer pipe - $59
6" x 6" pvc wye fitting - $29.50
6" 45deg fitting - $15.90
6" 90deg fitting - $21.50
I was planning on getting some more quotes, but thought I'd ask if that sounds about right as unless you know what is realistic, then it's hard to say f you are just being given a price to shut you up as they want to deal with big contractors and not us small home DIY people. For example, HD online has a 6"x 6&4 wye fitting for $13.50 but no store in all of Ontario or Quebec has and in stock, so who knows if this was a sell it to get rid of it price that never got removed from the system.
