Very SCARY Jet Air Filtration AFS 1000B

CalebL's picture

almost cost me my shop and a lot more tonight. I just got it delivered this afternoon. Took it home, unpacked it, put the eye bolts in it to hang, took the packing out of the inside, put the filters in place and turned it on.

The low setting caused the squirrel cage to wobble a bit, nothing that really concerned me. Turned to medium and the wobble went away. High setting and it ran pretty smooth. I then set the timer to 2 hours and started running some coping cuts on the router table.

After 2 hours the unit shut off but I noticed the squirrel cage continued to spin very slowly and it made a humming noise. I thought the fan motor was cooling down and paid no mind. I turned the unit back on and kept working.

About 3 hours ago I clean everything up, check the filter and it appeared to be working pretty well. I set the timer back to 2 hours so it would continue to clean the air and went inside.

I checked it after the 2 hours and it was humming a little bit but I thought it was normal since it had done that from the first time I plugged it in. So, I decide to go to bed. Lying in bed I can't get it out of my mind that the humming wasn't right. Bothered by this, I get up and go check on it. I open the door and the shop smells like burnt electrical. I run over to the unit and it has went from humming to a loud scratching with the squirrel cage slowly spinning even though the on button and light is clearly OFF.

I jump up and unplug the unit from the ceiling plugin. I take the filters off and touch the top of the squirrel cage, BIG MISTAKE. It leaves a burn across four finger tips.

I can't sleep now because I am so pissed. I have no doubt I would not have a shop in the morning.....or worse.

Anyone ever heard of anything like this?

"Anyone ever heard of anything like this?"  With an old hairdryer once.  Seriously, though, very bad news.  I would consider (think about, then decide) filing with the Consumer Products Safety Commission.  If several people report a similar incident, it could induce a much-needed recall.  If you're the one and only, no harm done.

Tell that to my fingers. It hurts just typing this.

I  mean "no harm" in filing the report, i.e., won't cause the company a major headache.   Sorry about your fingers, burns cause the worst kind of pain, and the fingertips are so ennervated!!

I am thinking more and more about filing a report now. Especially since I was told about the known issue with the lighting but Jet saying it isn't their problem.

"He claims it isn't a JET problem but that it is a florescent lighting problem."  IMHO, that is a completely unacceptable stance on the part of the company.  Normal working conditions in a large percentage of woodworking shops include fluorescent lighting. 


I would be inclined to work my way up the ladder in the Jet/WMH Tool Group hierarchy and get someone in a position of responsibility to discuss this problem, and their response to it.  ("Geeeeez, Jamie, stop thinking of this stuff!"  ROFL!)  For one thing, you'll find out if that is truly management's position on the matter.

Gizmos with remotes are never really OFF. Otherwise they cannot be switched on using the remote. If you keep the unit your only safe way of working will be to wire it to a switch which will cut off the power completely - but you have to remember to switch off.

One other palliative you could try is to "shade" the sensor unit from as much light as possible to reduce the interference. But again this is not failsafe.

Incidentally energy saving lamps might cause more of a problem than normal flourescent tube.

One would assume that Jet don't build the electronics themselves but buy them in. They are still responsible for the fault but will have to seek redress from their supplier. One messy lawsuit coming up.

I just read through this thread and I am very disappointed with Jet's customer service attitude.  But I am even more amazed by what appears to be a callous disregard of a significant liability issue.  It appears Jet is knowingly distributing a product that has the potential to cause major lose of property or worse.

I called Jet back again this afternoon after I sent the damn thing back. The TS guy named Jim told me that other than send me another one there is really nothing they can do about it. He claimed they haven't changed anything with this model as far as the electrical since the unit first came out and that it wasn't a Jet problem. I told him that I had read that they planned to address this issue and he told me that wasn't correct. There is nothing in the works to change anything with the model as far as he knows.

I told him that I have requested a refund and do not want another unit. I told him I had already purchased a Steel City unit and he told me that if it used a remote it would most likely have the same problem. I told him that in all the research I did on the SC unit, I had not found one instance where someone reported a problem like this. However, I found numerous cases that Jet had problems after I knew what to look for. He acknowledged that they have gotten a lot of calls about remotes not working and the units either don't shut off or turn themselves on.

He told me that they did move the sensor further back inside the enclosure to try and remedy the problem with the lights but so far it hadn't made much of a difference. It did however, limit the remote strength. You have to point it directly at the back of the unit to get it to work.

I told him how hot my unit got and the risk of fire but he claims the unit would not catch fire. I told him it got hot enough to burn my fingers by touching it and he didn't seemed to be concerned.

After about 15 minutes I told I could see I wasn't going to get anywhere with this issue and that I wouldn't purchase another Jet product again and hung up.

In all the times I have called a CS/TS person, I have never had an experience like this. This was the second one I talked to and they both reacted the same way.

I have had the JDS unit for seven or eight years, fluorescent lights , no problems. If Jet can't figure it out, that's ridiculous. Let's design a product for a known environment, but who cares if it actually will function correctly or not? Don't they test these things? What type of lights are in the factory that produces this unit? How dumb............... oh and dangerous.

Best,

John

I had to have Jet replace my air cleaner because of some kind of electronic problem. It would intermittently speed and slow. They were very prompt about getting a new unit out to me. New one is fine.

I've had one for about 3 years and it gets used average of 6 hours a day. But... when I come up for coffee, I do turn it off. When I leave the house I turn off a coffee pot for that matter even thought it "supposed" to turn itself off. No problems with my Jet so far and it's been heavily used.


First thing I would do is warranty it and get a new unit. I would check it as soon as you get it as the humming and cage wobble would have told me I have a problem from the get-go.


Good luck...

Sarge, the unit was turned off when it was humming. It appeared to me to be the motor cooling down. The wobble was very slight and only when it was on low speed. It did not vibrate or make any noise when it ran. The squirrel cage turns freely and smoothly.

The unit was turned off. It was not on. When it is on, it runs fine. The only way to get the humming to go away is to unplug the unit. Last night, when I went to unplug it was making more noise turned OFF than it was running on high speed. It doesn't make sense. I am calling Jet right now. I will give an update shortly.

This is the weirdest thing I have ever heard. The Jet Tech Service guy tells me it is my florescent lighting that is causing my machine to act this way. He told me to turn off my lights and run the machine and it if works correctly it is the lighting causing the problem. I told him the lights were off when the unit was burning up. He said it may be because they are on the same circuit.

He told me that this is a known issue with the system and florescent lighting. The two do not mix. He claims it isn't a JET problem but that it is a florescent lighting problem. I asked him how many woodworking shops he has been to that didn't use florescent lights. He said most everyone uses florescent lights. I then said it seemed to me that it was a Jet problem. Basically their solution is to work in the dark.

He told me to send it back and they will send me another one. I told him I would send it back but no thanks on the replacement.

Anyone have any feedback on the JDS system?

I've got 12 4" double row units of flourescent lights. That's BS to me as it is obviously some type of switch problem as it's still getting current to the motor after being turned to OFF. Considering what you were told I would also return it and get a refund as I hate to purchase from any company that I have more common sense about their machine than the technical rep.


Good luck with the refund... if you don't get one.. go higher in the chain of command. The JDS is well tauted.. I have used the Steel City.. you won't have those kind of responses from either's CS department.

I found the Steel City 65120 for $230 after the $50 discount. However, the unit is back ordered and won't ship until after the first of May.

The JDS 750 system is $340 and would ship now. I paid $330 for the Jet system so 10 bucks more for the JDS doesn't bother me much. However, if the Steel City is comparable then I wouldn't mind waiting a couple of weeks and save $100 bucks.

I think most of the units are fairly compatible in what they do, Caleb. I personally think the type filter used is more defining.


Good luck..

Ask the Jet guy for technical info on exactly what's happening. Fluorescent lights certainly can be electrically "noisy," but that's pretty much a fact of life in today's world. If the electronic equipment that you've designed can't tolerate fluorescent lights, the design is broken. Period.

Steve.. the cage is still turning after the unit supposely shuts down. That means electricity has to be by-passing the switch and IMO has nothing to do with flourescent lights. IMO.. the tech rep should know that if the motor is running.. squirrel cage spinning.. etc., then electricity is getting to the components with the switches in the shut off position which it shouldn't.


Similar to what I ask my son when he was around 5 years old. I had told him not to open a glass door case and take out my military medals. I opened his door one day and found the somewhat heavy metal cases in the floor. I ask how they got there.


I... I... I.. dunno. I bet the wind blew them or Aunt Laurie came over (Aunt Laurie lives 70 miles away) and put them there. 


And I bet the cage kept turning because of having flourescent lights in the shop. ha.. ha... ha..ha..ha..


I didn't replace my son but.... I would replace my rep that told me that for someone with a bit more common sense much less techinical knowledge.


Regards...

On the contrary, it could be entirely because of the fluorescent lights. Air cleaners typically have a wireless remote (mine does). If the electrical noise from the lights is somehow "jamming" or mimicking the remote's signal, it's very possible that the device is being switched rapidly on and off.

If that is the case, like the Jet CS told me it was, why is it that they take the stance of you have to work in the dark or change your whole lighting plan and that the problem isn't theirs but that it's the florescent light makers?

Seems to me that they would do something about it. The florescent light makers are not going to get together and change their product because it isn't compatible with a Jet air filtration system.

The CS told me that they get calls like mine regularly. However, this was the first time he had heard of the motor burning up like this. He told me that most of the cases is that the remote control doesn't work with the florescent lights in use or the unit turns itself on and will not shut off.

Since you can't change speeds or set the timer without the remote, I would think they could either change the remote or the easiest thing would to do away with it all together and add the buttons on the unit itself.

I can promise you, if I had known an issue like this was possible, I would have never considered buying it, regardless of how well it cleans the air.

Well, I think the answer to that is pretty obvious. If you can convincingly say, "It's not my problem," you've also managed to say, "I don't have to pay for it."

Ahhh... I got you. I did not catch (even though I have gone back and read that he set it for two hours) that this is remote.  Mine is not remote and frankly.. I wasn't aware they made one that was. I should have caught that from the beginning but I stay in a hurry it seems.


If that is the case... I am really clueless as I know nothing about how remotes work but I suppose it could make sense. At this point after learning about this situation.. I'm glad I got mine in the "remote-less" part of the century. ha.. ha...


Thanks for the explanation as I just became a bit wiser... I think?

Sorry about your problem with the Jet unit and the ridiculious service suggestion. Sounds stupid to me!


I do have the JDS unit and am very happy with it. I have not seen the Jet so I cannot compare, but my JDS 750 runs and works fine.

Caleb,


My day job is as an electronics technician and I can tell you that florescent lighting, in particular the electronic ballast types, are known for causing all kinds of interference to other electronic devices. This is not an excuse for shoddy engineering. A company making these type of shop dust filters should be well aware that florescent lighting is likely to be used in the environment where such a filter is deployed, and as such should have engineered their filter electronics for immunity to this type of interference. Some company's will try to get as much as they can from the American consumer, while putting forth as little as they can. If I had known this a year ago, I would have never purchased my Jet filter! Makes me suspect of their other products; and to think, I was looking at their JJP-12 jointer planer.

Bob, this was my first experience with Jet. The reason I bought this unit was because it got good reviews and I had heard a lot of good things about Jet. However, I don't think I will ever own another Jet product unless it is given to me....even then I will make sure to unplug it after every use.

Caleb,


It's the tech support response that really gets my goat. Finger pointing and passing the buck is just what I look for in a tool manufacturer.


Maybe someone from Jet will read these posts and contact you, telling you that the tech you spoke with is being dealt with and offering to make it right. I wouldn't hold my breath though.


If we (consumers) don't make a big deal out of things like this the manufacturers will continue to supply us with the lowest quality product and service they can get away  with.

I have the JDS 2000 with infrared remote. It's 5 years old and still works fine. I have mostly flourescent lighting in the shop. Never had any issues with interference.

Thanks sawdustdad. I looked at the Steel City and the JDS and both had great reviews. I ordered the Steel City because it was $220 with free shipping.

I'm sure Jet makes some pretty good machines but this was my first Jet purchase and will be my last. Their flippant attitude about the whole thing has really soured me on their products. I still can't believe they told me I should change my lighting or run the air cleaner with the lights off.

 I like your way of thinking, I have a Steel City jointer and I can say from my experience that there customer support is excellent and I think the jointer works great. Good luck with your new purchase.
