Has anyone used one of these Rotating Duct Nozzles?

http://pressurewash.com/catalog/pro...d=372&osCsid=e1a60fb7a3df17a9f128c628f826446d

If so, how are they?

Also, where is the best place to buy a couple of Rotating Duct Spinners? I found them for $180 which is good, but any alternatives? I almost think I could build them myself for alot less but not sure where to get the parts and if anything special is needed.
 
I had wondered about the effectiveness of the rotating nozzles as well. If they would perform as well as the spinner it would be a great value.
 
Well, 11 people have viewed the thread and only one reply of "I DONT KNOW" so I guess nobody has used one since there are only 11 or so people that hang out here.

I will just buy a few of them and test them out I guess.
 
never used one sorry
 
I would think that that would wind up in that "can" of used parts-you know, "What did I buy this for". Then its not like I have never been wrong!!!
 
Well, thanks for the replies. I figured it was junk, but you never know until you try it out. Just FYI, here is a place that sells the spinners for less than jackssmallengines:

The sewer nozzle is designed for pipe, not ducts. the sewer nozzle also uses a smaller, slicker, flexible hose. It is designed to force water ahead into the pipe, & pull itself through the pipe. The other holes are in the side of the nozzle and point back to clean the sides of the pipe and to provide forward thrust. I do not know why you say the sewer nozzle is junk, especially since you have not used the sewer nozzle. The sewer nozzle is not junk, just is for a particular use, and that use is not duct cleaning.

The spinning duct nozzle is designed to be dropped into the duct. It rotates and does a good job of cleaning. I used to take 20/30 minutes to do McD ducts. The spinner takes 3/10 minutes on McD. The spinner will also go down minor bends in the ducts. When pulling the spinner up, stand back! It throws grease and water out of the duct. For horizontal ducts, use the wagon. I have the 6 inch spinner in fixed and adjustable. the problem I have w/the adjustable is the arms keep coming loose. I also have a 12 inch spinner, it only gets used a couple of times a year. My spinners are the Mosmatic brand, purchased from Delco. I find Delco prices may be a bit higher than others, but the service is top quality. Also, Delco ships the spinner with the nozzles needed for your pressure washer, from parts in stock.

Dodnish, didn't Rusty tell you about spinners in your expensive class? If not remit to me the amount you save in your first 6 jobs.

I thought the spinner would go on the end of the wand, but I guess not. Why is it restricted to MINOR bends? I would envision it to go just about anywhere as gravity pulls it or you feed the hose downward.

Attach the Rotating Duct Spinner to a high pressure hose and lower vertically down a grease duct for cleaning.

How do you turn it ON and OFF? If you are on a roof, and it is attached directly to a hose, you have to turn the washer off each time you want to change from the spinner to a wand? :confused:
 
Just how much experience do you have cleaning exhaust systems?

Yes, you do have to climb off the roof, to turn on and off the pressure washer.
1. turn off PW.
2. return to the roof
3. disconntec the wand
4. connect the hose
5. off the roof and turn on PW
6. return to roof
7. Chase down the spinner
8. lower the spinner
9. raise the spinner
10. climb down the ladder
11. turnoff PW
12. return to roof
13. remove spinner, install wand
14. climb down the ladder
15. turn on PW
16. climb ladder

Or do what I do, tie off the hose, and rappell down. Use Jumar acenders to climb hose.

I do not even use a ladder any more. The trick is to get the hose on the roof and tied off first.

That is WAY too many trips up and down the roof (for me).

I'm thinking a shutoff valve on the end of the hose would be much much better and cost effective. Just shut the valve off, disconnect spinner and change wands.

OR

A section of hose with a quick connect on the end that would connect to your wand so you can quickly change from spinner to nozzle. This would also allow you to have FULL control of the ON and OFF of the spinner.

Or am I missing something?

We have a special hook we use so that the hose catches on before we ascend it.

My statement was refering to Rotating nozzles, not spinners.

I've always thought cleaning the duct was a waste of time anyway;) The time it takes to set up a ladder tip the fan and clean the ducts would tie up way to much of my schedule.:rolleyes:
 
Some of the systems that we've done over the years have a lot (300 feet) of vertical and horizontal duct that must be cleaned. Here is a picture of our duct spinner that we made for our use 10-12 years ago.

We use a plumber’s tape to pull it through and the hose to pull it back.

I have one of those rotating duct nozzles. I primarily use it to clean McDonalds ducts above the hoods, I put it on a wand and stick it up the duct, it is small enough to get by the links and the McDonalds duct are round and small enough for it to be effective. I did experiment with putting it on a hose and lowering it down the ducts with some success, just not enough to warrant carrying the extra hose to the roof every night.
 
You can not purchase from that site, or Mosmatic. You must contact a dealer.:rolleyes:
 
Ah yep. Its for information purposes. :p Thank you captain obvious.

We use a foot operated valve to control the water flow, this leaves both hands free for controlling the hose. Our foot valves are set up with quick disconnects and our hose between the PW and the top end quick disconnect has a ball valve. No need to go down stairs, or rappel down the duct or back wall, no jumping off the building. Just shut off the ball valve and switch between the gun or the foot valve and spinner.
