Hey Joel

After posting this, I found the same seller has a ONE speed unit he's selling as well, but has this exact same picture in his listing....So I don't even know if this is the ONE or TWO speed taken apart.

 

[rainbowjoel]

that picture u posted is 2 speed model.

Think the extra HEPA filter may be in the peice on the extreme left-this would have the circuit that drives the motor.I don't know if I would buy this--did the person taking down the vacuum take the static protection procedures in taking down the vacuum.Supposidly only dealers service dept are given the training on this-so says the one in my area.

Oh, I'm not buying it........It was just a picture I found on Ebay of someone selling it.

But there are a lot of companies selling refurbed 2 speed Rainbows.....

Greatvacs.com

Goodvac.com

Rainvac.com

I'm sure they are all aware of the static issue. Not sure they are authorized though. I have no idea how that works.

The static issue is dealing with MOSFET device equipped electronics devices-the Rainbow E2 motor drive is one of them.The MOSFET transistors and IC's can be damaged by a static electric charge that builds up on your body.The MOSFET equipped device has to be worked on a special static disaptive workbench mat and you are grounded with a special resistive wrist strap.the wrist strap has a resistor in it so you won't get electrocuted if you contact something live in a circuit-of course the Rainbow is disconnected from the power soruce.But current limiting ground in the wrist strap is required by OSHA safety regs.Rainbow gives special factory training to their authorized service reps on this.They also mention the machine has to be properly reassembled or it won't work properly or for long.I am in the electronics business and understand this.So I am not going to take my Rainbow apart to the component level.I would only purchase a refurbished E2 from an authorized Rainbow dealer to be safe-and the machine would likely have a warranty-the others may not.

I was reading on Goodvac.com and the site owner mentions that you must be grounded because certain things are static sensitive. So apparently he knows this........His site seems to be most about Rainbow inside and out, so he must know a lot about the machines. Perhaps he used to work for them or something. I don't know.....

i wondering if thats the Hepa filter. Try turn on with out Hepa filter and put the case cover back on, if it still makes the noise???

 

[aarons1584]

Hey, sorry I never did update. I actually bought a new HEPA for it, and it reduced the noise. You can still kind of hear a slight whistling noise, but not enough to bother anything.

 

[rainbowjoel]

oh ok. Oh well are u still going give to ur mom? mine sounds little quieter since i brought the Hepa filter last weekend. mine was so dirty i guessing the previous owner didnt add enough water or something. So i had cleaned but didn't dry decided remove hepa filter and have casing blank. lol

RainbowJoel:

My E-Series one speed has no HEPA filter in it. If you change the water like it should be, and don't over emulsify the water with fine dirt, the inside should stay relatively clean.

yep i do change water often.
