Thread: Oneida super dust deputy kits

Whilst I can't help you directly with any advice on that device (apart from mentioning that it's going to reduce your airflow), it would help to know what you have to start with.

How many machines and what sort of machines have you got that need extraction?
What kind (make, model etc) of extraction do you have now?
How is it all connected?

From there, we can start to give you some meaningful input on how to improve things.

I would also highly recommend doing some reading through this section of the forums, particularly the stickies at the top of the page - there's a lot of useful information here already that will get you a good idea of the general idea/approach to dust collection.

Hi MM

Thanks for your reply.
I have the Sherwood 3HP FM400 1900cfm d/e.
https://www.timbecon.com.au/3hp-dust-extractor
Located in outside shed, 100mm pvc from inside garage workshop to inside d/e shed.
100mm flexible hose at both ends; from machine & to d/e.
It works well, but I am trying to get the best out of a less than best installation.
Also trying to reduce the amount going into the clear plastic bags because changing them is not a lot of fun.

Unfortunately that DC the impeller is too small so using short lengths of 4" ducting is never going to draw more than 425 CFM through that size ducting and adding any cyclone is going to make it worse in terms of air flow and dust collection terms.

A cyclone means while you will have less to empty of the clear plastic sawdust bags but you will still have to empty the cyclone bin anyway so its swings and roundabouts on that score. A lot of people worry about too much about cleaning the filter bags but all you need to do is give them a good shake, wait for 5 minutes and then removed the sawdust bags. Don't worry about getting the filters anywhere near pristine again - they actually perform better when they are "conditioned", as long as they are not fully caked over with dust.

The worst thing about a cyclone on a small DC is that the reduced flows means less fine dust will be collected at the source leaving it behind in the shed. You will hardly ever se this dust as it is too one to see but it s the one that is most significant in terms of health

The way too get more flow is
Don't use a cyclone
Ditch the 4" connector on the front of the DC and replace it with a 6" port
Run 6" ductingto machinery
Open up ports on each machine to fully accomodate the 6" ducting

If you still decide to go with a cyclone and basically collect chips with your setup, the fine dust can be handled by using exhaust fans - the target is 20 room air changes per hour. Ordinary bathroom fans will work as long as enough of them are used.

Thanks Bob

ALWAYS good info from you.
I accept the increased port and ducting advice, but that would require some serious work in my circumstances.
The Oneida units are expensive which is why I started this thread.
Seems like not worth it for me; which is what I set out to establish.

Yeah. not many free lunches in DC .

I have the 5” Super Dust Deputy on a 2HP blower. For 3HP you need the 6” SDD which Timbecon no longer appears to stock. In fact, the 5” model is out of stock too.

I’m extremely happy with the SDD. I just thicknessed a heap of recycled oregon from a mate’s decking. It filled the dust bin twice. It was much easier to empty the bin than stuff around with the plastic bags on the original DE. Perhaps your DE has a better arrangement for attaching the bags, but mine was a nightmare. Depending on how much sawdust you generate I would definitely consider a cyclone of some description. But you will definitely need to upsize the ducting to make up for the loss induced by the cyclone. In my case going from 4” ducting to 5” drastically increased airflow, even with the addition of the SDD. Going to 6” would be even better.

You asked for good & bad:

Good:
excellent separation
compact
Plug and Play

Bad:
expensive for a piece of blow moulded plastic
out of stock!

Not just out of stock - it doesn’t even appear on the website. Have Timbecon stopped selling the dust deputy?
At $550 for a bit of plastic, maybe they weren’t selling any?

Now Timbecon is unique in not selling any kind of cyclone solution. All their DC are felt bag. Seems like a strange omission.

I would like a good, bad, and vfm etc review, please.

Have been trying to improve my d/e setup without spending too much;

now thinking the gov support payment should go on something beneficial to my health.

thanks

Keith, I have the SDD with 5"/6" in-outlets into a 2 hp Carbatec DC with 1micron canister filter and short 5" hoses (from Hammer machines). All this is due for the next upgrade, but it soldiers on. I keep hearing Bob's voice in my ear about the drop in power when the SDD is connected. So, a few weeks ago I removed the SDD and ran the system without it. The result was a fine layer of dust in the workshop. Back went the SDD, and no more dust. Bob, what do you make of this?

Regards from Perth

Derek

Derek,
I have the 2HP Carbatec with the canister filter and find while a huge improvement on the cloth bag I can not prevent some dust leakage from the unit. Main problem is getting a seal on the short pipe from the blower to the main unit as this is positive pressure. For this reason I wheel the unit outside. I do not run a cyclone with it. Your cyclone likely stops most of the dust before the blower so reduces that problem.
Regards
John

Hi Keith, I bought a dust deputy some time ago when the exchange rate was a lot more favourable than it is now. Mine is steel but the plastic version should function the same.
I use it mainly for extracting the dust from my Festool 150mm sander. (the only Festool I have). It works really well, the vacuum cleaner has a dust bag and a secondary cartridge filter. 95% + goes into the bin below the cyclone.
I also use it for vacuuming the floor in the shed.
If the above is your application it is a worthwhile acquisition if you can get one....
The hose size does not allow enough air volume for it to much use for anything else.
I have attached a picture of the setup.
Cheers, OldGrowth

OG, the small DD is a great small cyclone for that purpose. I have one similar. However, the Super DD (SDD) is a Large version of this, for the dust collector ...

Derek and Bob. Have you guys ever thought of getting together to test the Dust Deputy to see how much it actually affects the airflow? I've always been curious but have never seen a test done on one beyond a pile of You Tubers saying "See how much better it is." If Derek took it to Bob's place he could simulate different DC's by playing with his VFD and test duct setup. That would answer the questions on how much the airflow and static pressure is with and without one. You guys could wear masks, gloves and not hug.

Pete

Thank you to everyone who has contributed to this post.
Some very good info and variety of applications.

Cheers
Keith

Onieda told me the 5" SDD is equivalent to a 10ft length of 5" flexi.

I've never seen any airflow measurements for the Clearvue either.
