    Very well made! 01/01/2020 11:19:10 PM

    I ordered a cyclone separator from another company (which I will not name): one piece plastic with a paper barrel. I sent it back when I reviewed the Grizzly Growler. NO COMPARISON! The Grizzly product is mostly metal, has wheels, can use a bag, has a window to see the dust level and works great! I am very pleased.

    Really pleased with this 12/24/2019 10:06:19 PM

    I connected this to my 1.5 HP dust collector and it has really made my dust collection a lot better right off the bat. I purchased this a few weeks ago and since then have worked a few small projects using roughly 30 board feet of walnut and maple. This includes using the planer, jointer, bandsaw, tablesaw, and router table. Immediately after connecting it I noticed that the volume of air being moved had increased significantly. The dust collection at my tablesaw is the most noticeably better - the suction is stronger and more consistent now. The container on the Grizzly collector is currently just under half full and there's less than a cup of shavings/dust in the collection bag of the second stage - and a bit of that is from making a few cuts in between cleaning out the collector unit and setting up the Grizzly piece - the amount that has accumulated since I connected the Grizzly collector is minimal.

    Nicely made 09/01/2019 4:21:33 PM

    Only thing I wish they made with it is a wall mount. Without it it is difficult to change out can.

    Great product - better price! 08/23/2019 5:16:40 PM

    I bought two cyclones to install ahead of my two portable dust collectors. The went together easily, work great and have made emptying a breeze compared to the hanging cloth bags.

    This dust separator has been a great addition to my shop. I have a 2HP Grizzly dust extractor and decided to add this and they work great together. I have better cfm at all my machines so less dust in my shop. AWSOME

    This thing rocks! 05/21/2019 11:59:12 PM

    I recently added this to a Shop Fox W1666 dust collector and am really happy with the way it works. It does seem to trap everything in the dust bin before it ends up in the collector bag. I've dumped it four times since I installed it and I really don't see anything in the dust collector bag yet. It just works great. With this and the addition of a Grizzly pleated outlet filter, it's raised my dust collection to another level. Great product!

    Just what I needed 03/07/2019 12:15:46 PM

    I had been looking to add a stage to my dust collection system. The trash can stage I had added was not effective and it seemed most of the cyclone options were over priced. This system is well made and effective. I have been making hickory furniture using the system for over a month now and i have emptied the 25 gallon tank 10 + times and the plastic bag collector under my systems filter remains nearly dust free. I mounted the cyclone on the wall so it is easy to empty. Mounting was not something the system was designed for, but was not terribly difficult. This is a good value and for me a must have in my shop.

    UNBELIEVABLE DIFFERENCE! 02/23/2019 1:27:50 AM

    Wow! I absolutely love the Cyclone and can't believe I waited this long. Since connecting it to my HF dust collector, my bag has been very lonely, my planer works much better, and the dust has been reduced dramatically. Again, I wish I had installed this years ago. Couldn't be happier - and if you're on the fence, don't be! Well worth the money!
