POWERTEC70292V 4" Cyclone Dust Collection Elbows and Couplers Separator Kit for Woodworking Debris Containers, Buckets and Barrels

The media could not be loaded.  Let's start with the basic question: Is this a viable alternative to an expensive, pre-built cyclone? YES. I have been more than thrilled with the performance, though I do wish I had a third arm for installing.You are likely here because pre-made 4in cyclones are kind of rare, and really pricey, since most 4in port collectors are already two stage. I am using a 1.5hp for my shop.What is the catch? Well, you need your own bin, and it needs to be fairly large, to appropriately space the inlet/outlet. If you don't have one already, factor in the price. Another review mentioned an orange box store metal bin ($34ish) and I went with that. It worked out perfectly, but does take up floor space. I had to put mine on a mobile cart, as I basically work in a 1-car garage sized shop. You also will need to cut metal if you go with this route, but the right blade in the jigsaw works wonders... it's super loud to cut, so wear hearing protection.Install time - about 1hr. The toughest part was holding the inner and outer inlet port together while you try and line up the four holes you have drilled, all while feeding bolts through. They include both short and long bolts, and the long bolts were essential in order to apply weather stripping. They really thought it through. The nuts are the type with a rubber-ish interior, so they don't just hand tighten. You have to wrench from the start. I used a fixed wrench and then my impact to drive the bolt. You get the hang of it after the first one.The ports are nice and thick, so they won't snap under pressure, and also have an extremely tight fit (with the PowerTec hose), which is good in my opinion, albeit a bit annoying the first time.I was a bit concerned that the large can may cause suction issues, as you need to move a lot of air. My 1.5hp collector made it look easy, and had so much pressure it caused the metal hose to bend in a bit when initially turned on.If you set up the ports right, and your DC is powerful enough, you get a great flow, and I would estimate it removes 95-98% of chips, and really helps protect your filter if you accidentally vacuum up a screw off of the floor. It took care of the chips and dust on my cabinet saw and 13in planer with ease.I am currently editing a video about the install and performance, and hope to have it up online in the next few weeks, so depending on when you read this, there may be a longer video online to watch, if you need more convincing.Overall, this was a $70 cyclone (plus $20ish for the hose, which you may not need), and I can't imagine a $175 collector can do anywhere near double the performance. You'd basically be going from collecting 95% of dust/chips to maybe 99%, but you have a bag on your collector to pick that up anyways.I will note that due to the power of the suction, you can only fill the can that I chose about 60% of the way before the chips start being picked back up, as there is no inherent feature to prevent that, which other, far costlier cyclones may have, but I don't know for sure if they do.Great buy - 10/10

I wanted a cheaper alternative to the cyclone systems sold by other companies so I gave this a try with a medium sized cardboard barrel. It works great! No complaints!

These are great for their designed purpose. They work very well and are easy to install. They are a little expensive for what you get, in my opinion.

For people with a small shop this is a good option for a dust collection system. I combined it with my very small bag system and a 20 gal trash can. It has extended my collection ability and made clean out much easier. The recommended a metal trashcan and I used a plastic one. It works great with what I bought.

Installed these on a metal trash can. I just used the provided template to cut the holes in the lid with a jigsaw, drilled the holes. I added 3/8" weather stripping to both fittings for a good air tight seal and attached them to the lid with the provided screws and nuts. I also added weather stripping to the rim of the can. You can see in the photo it is doing it's job and separating the shavings so they don't go into the dust collection bag. Much easier to dump them out of the can and it saves wear and tear on your dust collection system.

Many manufactures charge three and four times with this kit costs. I cut both of these fittings into a plastic garbage can lid and it works great! I am surface planing 300 ft.² of Trex decking, and without this, it would be a disaster to clean up, I’ve only done about 25% and I’ve emptied a large garbage cans four times already! Worth every penny for dust separation!

the product works as expected

I was skeptical at how well this would work as a dust separator but holy hell, it works like a charm. Fills nearly to the top of the can before anything ends up in the vacuum bag.

Excelente calidad y funcionalidad 👌

safes my filter

Great product, purchase for dust separator

Work as intended. Easy to install. Comes with everything you need. Quick delivery.

Hooked it up to a 60l bin from Bunnings, still have strong suction and excellent dust extraction
