+1 to that, Tim!
Mine has a rattle and I have to slap it to quiet it down which spews dust out. Little counter productive!

Thinking of getting 2. Thoughts? There is a very similar Jet and ShopFox, just cost more. Mike |

Mike, I've got one of the larger size Jets mounted on my ceiling in my 15' x 22' shop. I does a great job for me although I don't have a way to measure the microscopic dust. I have changed the filters to HEPA type. |

I have a Jet AFS1000B mounted on the ceiling in my shop. I replaced the original filters with Wynn Environmental pre- and internal filters. It is very effective. I confirmed this with the Dylos particle counter I have. If you're interested, you can read a summary of testing I did about a year ago here:https://www.luthiersforum.com/forum/viewtopic.php?f=10101&t=51532&p=678286#p678286 |

How does it pick up dust down low in the shop? Do you have to use a fan to make air movement to drive the dust towards the filter? Ed |

Ed If the air filtration box is located properly, it sets up a strong air flow that is vertically circular. Even below bench top level, the air flow is strong enough to carry fine particles upward to the intake side of the box. In my shop, all the fine dust is generated at waist height and above so the air flow takes the fine dust upward no problem. I can actually see that happening when I'm sanding something on my bench with the drafting lamp on. I can see the dust in the lamp light being sucked upwards toward the intake side of the box. The flow rate on the Jet is enough to filter the volume of my shop about every 5 minutes. I don't have a central dust collection system so I use the Jet in addition to shop vac dust collection from my drum sander, belt sander, router table, and band saw. |

https://austinair.com/shop/healthmate/ 400 cfm of Hepa. Cheaper than a Dr visit and a few tests. I use this inside where I don't make too much dust. Hand sanding, small routing, drill press, disk (with hood) & spindle sander with festool dust extraction. Big machines in the outside portion of shop. |

Most of these ceiling-mounted filtration units are similar design with similar options available, and filters can be upgraded, as described here. My biggest complaint? NOISE!!! Yes, I have much louder machinery and a big dust collector, but these operate for a rather short periods, and I wear hearing protection. To be effective, the air filtration unit needs to circulate continuously, and that disturbs the quiet of my “happy place”. I confess, I don’t use mine as often as I should. My bad.

Another thing that I think is important is to collect the dust as you make it. In addition to my Oneida cyclone I also have 4 HEPA vacuums in the shop to collect dust as I create it. M |

Your shop volume is about 1/3 bigger than mine so it might depend on where the sources of dust production are located in your shop and where you place the unit. If the sources of dust are clustered in one part of your shop and the unit was located to concentrate the air flow there, one unit would probably be fine. If your dust sources are spread out around the shop, you might benefit from having two units that work together to create a circular air flow around the shop space. If you are thinking of mounting a unit on the ceiling, then how clear or crowded your ceiling is would probably factor into it too. |

I thought the grizzly model was similar. It is not, about half the air flow. Guess I will get the Jet. My biggest dust source is sanding (palm sander), and chop saw. Rigid spindle sander too. I am sure I get dust from the drum sander, even though its hooked to vacuum. Plus Jet will match my tools lol! Question: It might be obvious, but I hate how dust settles everywhere in my old shop. Will I notice a considerable improvement? I want my new shop to stay clean as possible |

Do you have a downdraft table for sanding? Also, what are you using for dust collection? I have everything connected to my Oneida Cyclone, a 2'x3.5' downdraft table and the Jet air cleaner in the ceiling. I also have a Festool HEPA shop vac for cleanup. I am NOT anal about cleaning but my shop stays pretty clean just by using what I do have while I work. |

Steve, def need a real dust collector. New shop, need to invest. thoughts? I'm using a roll around DC. Mostly for drum sander. |

I want my new shop to stay clean as possible If you don't have a "real" dust collector system now, then you're likely to see a very noticeable difference. Before I got the Jet, I was relying on a shop vac with a Dust Deputy which wasn't really cutting it. Dust would collect everywhere after a while and required periodic extensive vacuuming to clean it up. After a couple rounds of that, I decided that, besides being annoying, it couldn't be good for my lungs. Adding the Jet didn't eliminate dust entirely, but it did reduce it by a huge amount. It helps to pay attention to the air flow out of the Jet as an indicator for when the pre-filter needs to be vacuumed off or replaced. |

Hey Mike. The biggest difference in dust collection for me came about when I installed my Oneida cyclone. It was a big expense and the ducting was also expensive and a lot of work. It's a big machine for a small shop but turned out to be well worth it. I made the downdraft table and located it right next to the cyclone so I could get max cfm; it pretty much captures everything when I sand. As I said, I have the cyclone connected to everything; tools that didn't have a DC port I made something such as my Rigid spindle sander. Happy to share more if it will help. |

Good dust collection requires sufficient cfm at the machine and for low pressure systems (like dust collectors) that pretty much translates to a 6" duct system. In order to run duct work long enough to cover your entire shop the dust collector has to generate a sufficient static pressure. Length of duct run, number of machines in use at the same time, duct diameter, blast gate diameter and dust collect static pressure are the numbers you need to consider as you plan your system. Even if your tools only have a 4" DC port it is still good to have as much of the duct work as possible at 6" (or more if you have a big enough DC). My Oneida Dust Gorilla starts out with a 7" duct but will only support that diameter for about 10 feet after which it goes down to 6". This is why my downdraft table is right next to the cyclone, gives me max CFM on the table for sanding and, I have to say, it works really good. Since I made my own downdraft table I'll post a few photos. Here's a side view showing the duct work. Blast gate is right at the bottom of the funnel. Attachment: IMG_2254.JPG Here you can see how made the box funnel. Metal interface to the blast gate was made from HVAC duct fittings from the big box store. I also used HVAC duct fittings to make the DC port for my Rigid spindle sander. Attachment: IMG_2243.JPG Here's a shot of the top. You can see the cyclone in the background. Holes are 3/8" in Masonite over a 3/4" plywood deck with 1/2" holes. I used masonite because when it is sanded it doesn't have a scratchy surface plus the Masonite pegboard already had holes in it, unfortunately, the holes were too small and turned out to be restrictive so I made them larger. Although the Masonite has a pretty soft surface, when I'm sanding finished parts I will put the part on an old t-shirt or towel to protect the finish. Immediately behind the downdraft table is my go-bar deck, it is mounted on a wheeled cabinet so I can pull it out in the middle of the floor and spin it around while I work. Attachment: IMG_1455.JPG
