Coal Vac - more fine tuning!
Today I made up a new "nozzle" for the suction end. I went from 2"-1.5" PVC. Quite a difference!
I currently have 2 vacs set up my older Craftsman 6&4.5 hp. I have 1 dust deputy on the 4.5. Right now it seems like every 2 weeks I will be cleaning the filter. So my plan is to modify the system ,since it is working so good, to this. 2 new Rigid vacs 6hp,1 more Dust Deputy. Then fabricate a sound proof box for the vacs. Also incorporating the filter bags. Since I run my K2 all year this will be a worth while investment.

If you have easy access to the outside i would route the vac exhaust outdoors. Even though the filters do a fair job, you will still get fine dust distributed throughout your basement. Your horizontal PVC run will collect a lot of the dust with the static charge.

I just ordered a dust deputy and getting ready to start mine. I was going to use 2" pvc going to the tank that the coal will collect in above the hopper. Planned on using shop vac hose attached to the 2" pvc to suck out of my storage bin. I need a flex joint above the bin so just wondered if that would work? Do they make adapters to attach the large shop vac hose to pvc?

I used a heat gun to soften the 2" PVC and then shoved the shop vac hose in for a custom fit. It worked great. ..

Why not parallel the vacs before going into the dust deputy you already have?

Yes, a Y configuration. Gives you double the airflow (CFM) with identical vacs (theoretically). I would not think it matters if vacs are identical but you wouldn't want them to be too far off from each other
