Dust collection help

it really does depend on the CFM and pressure the DC can produce. 6”-8” might be more fitting for higher power Cyclones, although your 2HP may be able to handle it. however – I think a 5” PVC pipe (or metal for better performance -less resistance) would be a better choice, with 4”/5” drops. it’ll give you a better CFM than the 6” piping will, and will connect directly to your DC with no need for reducer.

-- When in doubt - There is no doubt - Go the safer route.

I would consider branching each side of your “U” into a separate zone with a gate.
27 feet is a pretty long pull to keep particles airborne.
You motor will run cooler with 6” pipe than with smaller sizes. ( Static pressure)
I ran mine with 6” spirolok metal pipe and 4” drops.

Thanks for the comments. I’ll need to figure out the CFM,and zoning is a great idea.
Thanks again.

If you use PVC piping be should to ground.

You should avoid PVC as it causes turbulence inside the tubing that robs efficiency, 4” round metal ducting is probably the best, in my opinion. Avoid 90 degree turns use 45 degree wyes at your take off points. 4” flex tubing to your blast gates and 4” flex tubing to your devices. I am also using the cyclone garbage can and top for big chunk collection. Helps save down time on bag cleaning. Easier to empty the can than the bag.

You might try Google for CFM information. Enter Grizzly (dust collector) and the model number. I’d do it for ya’ if I had the model number.

Thanks UnionLabel I’m still resesrching the PVC/metal issue I appreciate your input. I will be putting in some kind of garbage can collection in.

Thanks John,I e-mailed Grizzly and the reply was around 1400 CFM I appreciate the offer. I will keep you all posted with future updates.
