Hi,
I have had great success with several baffle builds for 5 gallon buckets and shop vacs. I also built a top hat for a 40 gallon trash can to use with my 3/4hp dust collector.
I have now outgrown the small DC, and at a demolition of a production line at work I found a dust collector that I ripped the fan out of to use for my new build.
Its a fairly large fan with a 14" steel diameter fanblade, and 6" tall, so it move a huge amount of air with the 3 hp motor.
I put a VFD on it so that I have full control on speed, ramping and current.
BUT, my major issue in my setup is that my basement shop has very low ceilings and the largest piping I can install are 4"
I would have preferred 6", but sadly there is not enough headroom. The longest stretch of pipe is aprox 21 feet, containing four 90 degree turns.
I run pvc pipes, and unfortunately no long sweep bends.
With the small dc and the thien top hat I managed to get 2300FPM at center of pipe inlet.
The new large fan has a 10" inlet, and I have built 3 filterbags on the exhaust with a diameter of 8" and 68" tall.
I will get some photos of my setup tomorrow.
I am going to build a new top hat, and was thinking about making it 23" in diamter and 11" tall.
I have two 4" pipes coming in from different parts of the shop, And was wondering if I should make an inlet with the 2 pipes stacked,
Normally Only 1 pipe will be used at a time, but I might reconfigure the lines, so that I get for example one 4" line for the bottom of the table saw, and one 4" for the overhead arm dust collector.
I am planning on ending these pipes in a smooth transition to a square inlet.
My major question is What size pipe would be best for the output?
Would it be wisely to make a 10" output, as long as I only have a 4 inch line on the input? ( maybe two in the future, or more),
So if I add more pipes later on, I will not have to rebuild., But are there any negative sides of using 10" in my setup?
How will this affect the FPM in my lines?
Any info is greatly appreciated
Best regards
