Oneida Air Systems Dust Deputy 2.5 Plus Cyclone Separator XL: Highest CFM Collector for Wet/Dry Shop Vacuums with Lid (New DD 2.5 Plus)

Not much more can be said about this dust collector. It has save a whole lot of money not having to buy filters. It works like it was advertised. Well built product.

This simple item does a really nice job keeping your garage clean during a variety of woodworking projects.I didn't have a lot of money to invest in a fancy dust collection system. I already had a Shop Vac that could be used to operate it. It has done a great job keeping my shop clean.Pros-Low cost item that works well. It was super easy to install and use with an existing Shop Vac. As long as you have the right connection and a strong vacuume it will get the job done.Cons-Not quite as powerful as a more expensive system. My Shop Vac tube sometimes detaches from the unit, which can cause a mess.Overall, this is a great item for low cost. I highly recommend it!

I used this with a Hyde Tools vacuum drywall sander, a Harbor Freight shop vac, and an inexpensive HDX 5 gallon bucket. A Home Depot 5 gallon bucket would work also. I had a large area of ceiling to sand (the worst for dust!), but when the job was done, the dust was in the bucket, not the shop vac and all over the house. As a bonus, vacuuming the dust made the sanding screens last longer. One connection required some duct tape, another required a clamp (included). Very happy with the results.

UPDATE: see modifications for better performanceThis is my first dust separator as I'm trying to get into woodworking. That being said... I bought the "DD Plus" kit thinking that it comes with more of the pieces I'd need to make a stacked cart with my shop-vac. I thought wrong.Ultimately I love the separator itself. It does what its supposed to and surprisingly well, but does the "DD Plus" really provide extra benefit for $20? Probably not and def not to make a vertically stacked cart.--- HOSE ---The hose that comes with it (protape pur 330 as) seems like high quality and is not offered on amazon, but MSRP is well above Amazon offerings. Compared to the reviews of other 2.5" dust collection hose this doesn't shrink that much when completely blocking the hose. It also secures snugly in the shop-vac(branded) lockon connectors. However it is short (37"). That's not even long enough to stack a short 3 gallon bucket on top of a shop-vac. The length would only be good for side by side cart or to run the bucket free standing. If you use it as freestanding there is no way that it won't tip over. So now i'm hunting for more hose that is descent quality but doesn't cost as much as the included Protape Pur 330 AS ($130/25ft).-- ELBOWS --All the elbows do "fit" the separator and my 2.5" hoses, but they also fit pretty loose and are prone to falling off due to the steep taper. I've decided to use the elbow for the top outlet as it connects well to the dust collection hose with the hose clamp. Two comments about using it for the inlet. First, the elbow will constantly fall off the inlet. Second, The connection between a 2.5" shop-vac hose and the elbow will be loose and fall off.-- LID & MOUNTING HARDWARE--I honestly have no idea if the special shaped lid aids in the cyclonic airflow, but i can tell you it doesn't collapse, is precut/drilled for easy installation, and fits the buckets i've tried. One odd thing about it is that the underside of the lid holes for mounting hardware is molded with a hex shaped lip for the nut to sit in. This lip stops you from using washers on the underside of the lid to better disperse forces. The flanged nut must also be threaded onto the bolt upside down to sit in the recess though. As the top of the nut has rounded edges, the surface contact area of the nut to the lid as well as the nut to the lip are decreased and makes me hope that the forces applied on that smaller profile don't cause a tear out. Also, since you're mounting the nut upside down, you lose the knurling on the flange bottom to prevent backout and have to use locking washers. The whole thing is just an odd design. It honestly would've been better if they skipped the fancy stuff and just made the lid thicker plastic. It might almost be worth it to get your own standard or nylock non-flanged nuts to use.-- CYCLONIC SEPARTOR --Works great, no complaints there. I do however worry about it cracking in a tip-over. The thickness of plastic as well as the type of plastic used could lead to it shattering.===== MODIFICATIONS =====- 1/2" x 1/8" neoprene weather stripping around lid helps with dust particles escaping when moving the unit around while not under vacuum.- 2" rubber PVC coupler for inlet to stop hoses from falling off- Key hose clamps for inlet coupler- Direct connection without elbow to exhaust to allow for better airflow as sharp bends hinder airflow- Bridged key hose clamps for exhaust for spiral based tubing- Widened DD intake and exhaust ports with a rubber compression stopper and a heatgun. Noticeable airflow difference. 550F and incremental compression on the stopper. Also creates a flange on the intake port allowing the 2.25" vaccum hose end to butt up inside the flange inside the rubber coupler to remove turbulance in the 2" PVC rubber coupler siide chambers.- Ground down the DD Plus lids nut wells and added a second 1/4" washer under the lid with nylon locknuts. Spreads out lever forces of the cyclone chamber on the lid.- Upgraded to 0.3um/"HEPA" cartridge filter for the shop vac with a rigid "HEPA" cyclonic bag. No noticeable "fine dust" layer accumulation from tiny particles exhausting out the back of the vacuum. Under no delusion that tiny particles are escaping still, but it's no longer immediately perceptible as a dust layer.- Shop vac muffler/diffuser to decrease resistance of vacuum exhaust increasing suction. Would not do this without the "HEPA" upgrades above.

It works great. I have one. This one was a gift to a friend that was cleaning an old house. He complained that the filter would plug too often. Here you go...problem solved

I have used several Oneida Air System products for years and this Dust Deputy 2.5 is an improvement in air flow over their original dust deputy. Both do an excellent job separating the debris from the air and the filter on the shop vacuum last a long time as it gets very little dust. The quick release bucket lid is an excellent addition and made set up very quick and easy. You will save money by not needing to buy vacuum filters.

This has DRAMATICALLY reduced how often I have to clean off my shop vac filter. This is a must have. I SHOULD have gotten the whole kit to bind the filter to the shop vac body but I thought I'd make my own. A year later and I still haven't done it.
