Topic tags/keywords: 3hp dust collector super dust deputy

Greetings all! Been lurking on forum for a bit, but this is my first post. I am doing an extensive remodel on our house and decided to get serious with my tools to achieve the professional result I seek.

I just bought a 3hp Reliant NN 830 with 220v 15a 3450rpm motor. It is setup for dual bag/can filters, but I intend to modify to only use one side with a single Wynn filter. DC will connect to TS, router table, miter saw, jointer, planer and floor.

I am trying to work through some variables, the first being which Super Dust Deputy model to get (regular or XL)? I plan to use heavy gauge snap HVAC pipe in 5 inch with regular SDD. Only 1 machine will be used at a time.

Appreciate any guidance! Thanks!

Ed

Three horsepower is a pretty big blower. I would not choke it off by using only one Wynn filter. I would also choose the Super Dust Deputy XL for best performance.

Almost certainly that blower will require the larger unit (SDD XL) to do it’s best.

Sounds like you need to do some more research – before you buy or modify anything else sit down with a beverage and snack and do some reading on Bill Pentz's site

Thanks. I did not know if SDD dropped pressure and should try to over power, but seems the XL one will allow higher cfm with my 3hp?

Nice. After some more reading, it seems a filter stack of 2x Wynn with a clean out makes more sense. Can you have too little back pressure if venting outside?

Wow. So much knowledge on that site. Seems that I should really try and direct vent outside. Still working through material but 6” ducting seems a must. Did not see SDD mentioned on that site. Are there any other cyclone separator option in same price range as SDD XL?

Thanks for the replys.

Ed, only vent outside if your shop is an unconditioned somewhat open space. SDD won’t be mentioned on there, keep reading if you haven’t seen already the only commercially available cyclone of Pentz’s design is from clearvue cyclones. You’ll be happy with the SDD XL and Wynn filters I suspect but do your own homework on duct size, type, machine fittings, etc. Or wear a respirator for fine dust and let the collector get the chips. I’m building a 5hp cyclone from Pentz’s design. Have the 16” impeller from clearvue and a 5hp motor, just have to get the cyclone itself built. Won’t be too much longer!

You can have too little backpressure, but that’s unlikely with your blower. I’m guessing that blower has a 12” impeller…and a 3 HP motor is plenty big for that size impeller. If you have “too little” backpressure, the blower tries to move more air, and loads the motor more. Checking the amp load on the blower is a good idea to see if it’s overloading. You will have the same effect bu letting too much air through the inlet. But I doubt any of this will be a problem for you with that unit.

Thanks Grant. I have commandeered our garage, which is oversized with an exterior door to rear, and live in N. Texas. I like the idea of getting fine dust out of space. Bill seems to say venting outside is always better if an option, but mother nature does her thing with temps and pollen. However a Wye with gates to outside and filter stack really does seem best of all. 6” snap is quite affordable and im understanding better the need to keep runs 6” instead of 4” and use 45s instead of 90s.

Thanks Fred. Not sure if my terminology is correct, but with back pressure I was thinking if I should be concerned about the size and length of pipe run to outside. It seems logical the 4” ports to my tool collection will make back pressure irrelevant unless clogged or inadequte filtering is used. Impeller is 12”. Great idea on checking amp draw.

Have you been to Oneida’s site? https://www.oneida-air.com/

They are a good technical resource and were very helpful when I was designing my system.
Looks like they recommend 6” duct-work for 3-5HP blowers and the Super Dust Deputy XL.

Check them out!
