Even a gentle breeze rotates the Cyclone 360° to follow the wind. It creates a powerful vortex that pulls odors up and away so they don't enter your RV living area. Low profile design. Attaches to any plumbing vent with no drilling into rooftop.

This vent completely eliminated potty odor caused by the vacuum effect when traveling with any coach/cab windows open in our Clas...s C. Its made to install over the black plastic vent pipe from holding tanks. The single improvement would be for it to come with a flange that would snap into standard round vent cap receptacles. Nonetheless, I am completely delighted, and it was the source of much attention from follow travelers this month on a trip in British Columbia.
After suffering the smells of outrageous fortune in two motorhomes
the last 10 years, we got a Camping World Cyclone Sewer Vent.... Long
story short, it works as advertised, no smells wafting in to the living
quarters at inopportune times.
The only misgiving I had was what I considered to be the somewhat
flimsy construction of the unit. BUT it has held up well in all kinds of
travel and wind conditions so I'm keeping my fingers crossed that it
will continue to do so.
Our Cyclone Vent is located in very close proximity to the Primary AC unit. One day after
a wind direction change, positioned th...e exhaust port directly in line to the AC unit. We
started to smell an odor inside coming from the AC. We had to turn off the AC and
open windows for the night. The next day I did a black tank flush, the winds changed
also and then no more sewer smell. Our issue could have been caused by tank
needing a flushing out and or the wind direction change which caused exhaust to be
directed into our AC air. I would consider this when putting on roof.
We're on our second Cyclone Vent. First one wiped out by low branch. We purchased a new travel trailer two years ago and could n...ot completely get rid of the tank oder in the trailer, so decided to try this roof vent. The oder was completely gone all the time!!! Very easy to install. Just watch out for those low branches with a tall trailer.
Normally products never work as well as it's advertised. This sewer vent is the exception.
Before I installed this vent I was ge...tting sewer smells when we were camped, parked,
moving or stored. I tried driving with the windows open and closed. I sealed the sink
drains. I poured vegetable oil into the toilet to form a seal. I kept the roof vents open and
closed. I used twice the normal amount of black tank additive. Finally I installed the
Cyclone vent and took it out for a 2 week trip. Neither my wife nor I smelled any odor during
the entire trip--absolutely NONE. We were ecstatic. It was a hassle removing the old vent,
taking off the old sealant, drilling the mounting holes, etc but it was well worth it.
The Cyclone works great! Really helps the control the odors. The instructions say to remove the old vent to install. I actually... just removed the vent cap, trimmed it back a bit and slipped the Cyclone in using the existing vent cap as the "ring" around the Cyclone. Screwed it into the vent pipe and siliconed everything. Have had no issues and it made the install a lot easier!
I suffered a similar problem last weekend when during a storm the vent blew off, leaving only the bent over rod. The last one I ha...d on my last rig worked perfectly. Wondering if there is a new quality issue?? Gonna order a replacement and see how long it lasts
I had an black tank odor issue in my travel trailer. The original sewer caps were brittle and cracking so I gave these a shot on ...both the black and gray tanks. first trip out, I stopped and went into the trailer and the smells were gone. My inlaws now have them on their trailer too!
These vents are well worth the money. I installed them on the black and grey tanks. It didn't take long to notice the difference. ...I just removed the old vent covers and added a coupler and short piece of PVC to extend them up from the roof about even with the top of the A/C unit. I didn't see any need to remove the old vent flanges either. I made sure my trailer was level before installing them and then made sure they were vertical so they can rotate freely. Caulked every joint too.
the old roof tank vent caused a nasty sewer stench to enter the RV at highway speed. This wonderful device keeps the horrible odo...r away. It is very easy to install involving only a few minutes on the roof, a screwdriver and some sealant.
I had my old standard vent knocked off by a low limb.
I decided to go with this model as a replacement.
It was super easy to ins...tall, just followed the directions.
I haven't noticed any smells in the camper since the install.
I'll probably buy one for the other vent soon.
I was skeptical enough not to buy similar products at $40 but thought
I'd give it a try at this price. Intalled easily (2006 Wi...nnebago Outlook)
and it really works. We get no odor while driving. We've cut down on
the amount of chemical we use. Very good product.
Since installing the Cyclone I have not smelled any odor from the toilet. No doubt the best money I have spent. Installation is s...imple although I did have to cut back the railing on the top of my rv to let the cyclone spin around.
I recently purchased this item after years of camping and dealing with
this awful smell ! It really works I don't have to worry ...about having
company come into my camper and smelling that awful smell !
My wife and daughter complained about sewer smells in the RV while traveling (usually at
highway speeds). I installed the Cyclo...ne with good results. We just returned from a trip to
Yellowstone from San Diego (aprx. 2300 miles roundtrip). Not one smell, NONE.
Couldn't be happier. It works!
Not sure yet how it will work, but the reviews indicate it does. Awful stink last year while in Montana in July, that's why I bou...ght it. I had to wait until I got home to install it - not exactly a field fix job. I had to remove all the Dicor sealant around the old vent cap, then I had to split the PVC connector that was glued over the main stack, before I could attach the Cyclone. It's not necessarily as easy as the instructions claim, but if you are reasonably handy, it's a fairly simple task. You can mount it fairly low to the top of your rig by sliding it further down the stack - as long as it can swivel and there is room to drill the pilot holes for mounting (with the flange pushed up out of the way). Some silicone to finish up and then some Dicor around the base the next day. Even with all the extras I had to do, the whole job took no more than 45 minutes.
We had purchased a used towable this winter, and it has had a very
bad sewer smell (the previous owner didn't clean out the tank... very
well). I purchased this vent after reading the reviews, and I am VERY
happy to say that after 24 hours of the trailer sitting in my driveway, the
smell is gone!! The installation was very easy although I did have to
modify it very slightly to fit my application. I think it took me longer to
gather my tools together than to do the installation. I cannot put into
words just how happy I am with this product. I recommend this to
anyone who doesn't want to smell their tank anymore.
We purchased this product because we keep getting sewer smells in the RV while driving down the road. Since we installed this pro...duct we have not had any odors from our septic system. It was easy to install. This is a great product!!! Would recommend to everyone.
Perfect fit. I removed the original cover and base and installed the new base and swivel vent. Use some silicone to seal it and fi...nished in about 20 minutes. Our first road test proved it absolutely effective while under way and while parked it turns nicely into the breeze and vents well. Happy camper!
(Newbie Alert: Read the directions & get all your extra supplies before you tear your OEM vents apart.) I recently bought this (bu...y 1, get 1 free at CW) after a 5 day camping event left our bathroom reeking like a blackwater tank. I flushed the tanks really well and installed the first one on the greywater vent (better to screw that up I figuired). It was the first time I had done any improvements my new 35' Class A. I didn't have the silicone caulk or gun, so the next weekend I ran back to CW & got it. I started as the sun was setting; It took me 15 minutes
on the first & about seven on the other. I was back in the house in 25 minutes! I'd suggest bringing a bottle of water and silicone (septic handling) gloves so you can wet the gloves so you can smooth out
the silicone from the caulk gun. We have gone camping three weekends since then and had two family cookouts (we use the RV as a base station). I didn't get a
chance to dump the tank last weekend (about 1/2 black & 2/3 grey in each 41 gallon tank) and we've now had a 4 days of 85-95 degree highs. Between the Cyclone Vents & the Orange drop-ins, nobody has smelled a thing! Overall, it is a cheap and effective product and easy to install.
We purchase the Cyclone for our Winnebago View. Probably took less than five minutes to install. It worked perfectly till it was k...nocked off by low branches. I'd like to put another back on, but it would just get knocked off
I had sewer smell in my old RV and just lived with it on my short camping trips by always dumping before moving. I was disappoint...ed when my recently purchased RV had the same problem. I decided to try a vent. It worked perfect and easy to install. Highly recommend. I am going to put a second one on the gray water vent also, as I've experienced one incident where water must have drained out of a trap during driving causing some odor.
I purchased the vent after I had been camping and had a sewer smell in the camper. After reading about the vent
purchased one. T...he ease of installing was just like it said and have been camping and with camper setting for peirods of time have not had sewer smell at all !!!
For those who can't determine gray water vent from the black water...Put this on the one that spells like your rig at highway spee...ds before your put this on. If you still have the smell, then you confused the smells of gray water vs black water and can swap them. And if you still can't figure it out, swap the vents at the gray and
black tanks with a cross over and you won't have to relocate this part and have entirely too much time on your hands.
We bought a new 5th wheel and the sewer vent a was very short. When we flushed the toilet and the air conditioners were on, the se...wer odors were drawn into our rig. The gases could not escape because of a design flaw. It was awful. We were told on a RV Forum to
switch to the Cyclone Sewer Vents........We did and our problem is solved. No more sewer odors....great product. Very very easy to install.......
Works great at eliminating those pesky odors in the RV. I've discovered though, that one must remove it when traveling.
While tra...veling into a 30 MPH wind in SW Kansas it blew off,leaving only the screwed on stanchion with the metal pivot
rod bent over. If not for that I would have given it 5 stars.
I was wondering how I was going to review these things if they worked, because unlike so many others when I made the decision to u...pgrade it really had very little to do with bad odors. The good news is that I made the upgrade all the same - as part of changing out the toilet and a few of the other roof vents - and the Cyclone's seem to work pretty
well. They certainly haven't changed things for the worse and in my mind, with an older RV, that's a good thing.
Love this item, we had it professionally installed and before we had the cyclone, we would sometimes get a little odor from the ba...ckdraft in the bathroom into the motor home while going down the highway. We drove 2 days before arriving at our destination after having this installed and had no odor whatsoever.
It works but if you have any overhead tree branches that sweep across the roof it will sweep off the vent. The central shaft is o...nly about 3/32" diameter and not strong enough. They need to strengthen the construction big time.
Purchased the cyclone (2) almost one year ago.Results are much better than we expected.The sewer gas smells were
strong when we ...traveled on the road.After traveling quite a bit amazingly there were no odors at all.Also we had trouble with odor when park at resort for long stays.I can say after staying the whole winter in florida this little fix did the
job also !!!
Great product at a great price. Had a horrible smell from my black water tank that no
chemical would take away, just installed ...the cyclone sewer vent today and bingo
problem solved and it saved me from buying a new black tank for $200 dol plus install,
I would absolutely recommend this product, i give it ten stars,
Thank you Camco.
Directions were a little fuzzy but able to figure out the installation. Fairly easy to install. Vents work as advertised. No blo...w back from either black or gray tanks while traveling and when parked in windy conditions. Just what we were looking for. Works as advertised. Recommend the product.
I installed these on my Holiday Rambler Endeavor. I read about issues with the top coming off so I used eternabond tape to secure ...the top to the bottom. They don,t swivel now but they work great no more ODDOR!!!!
Ordered to replace the vent camp on my motor home. Was very easy to install, but
haven't had a chance to see if it really works.... It should work much better than the one that came on it. I would recommend it.
I purchased a used coach and when my black tank was empty there was little or no tank odor. However put a couple of days of use in...to the tank,
hit the road and the smell was unbearable. We
tried everything, and the I remembered seeing this vent in a camping world ad. I went online ordered it, received in 3 days and immediately installed it.
All odor is gone, tank can be full or empty and the result is the same-no bad smells period. If you have tank odors and you have done everything else to eliminate the odors, buy this vent, cuz it works,
Great product, easy to install! I tried everything before I found this product, cleaning the
tanks with orange cleaner and laund...ry soap, still had an awful smell while driving.
Installed the cyclone vent and no problem!! We even had high winds while driving 60
mph and the cyclone was still secure to the vent pipe!! I would highly recommend
Recently bought a new trailer. During my shake down and inspection I found a crack in the sewer vent cap (the screw was over tight...ened to hold it to the roof). I went to CW to buy a replacement and saw this item. Like the idea of the wind moving the air directional. Installed (took only 10-15 minutes) and it rotated easily. After 3 trips, I'm glad the original cap was cracked. This a good device; moves the air / odor as promised.
Even though I have a 2014 motorhome, they still use the old style cap sewer vent
covers. I removed the old cover (1 screw) and u...sed a razor blade to smooth the surface
and installed this in less than 10 minutes (including going up and down the ladder)
This little unit is great. Redirects with the wind doing away with the every now and then
smell. They only come in white, but if... you get plastic paint they are paintable to match. It
does not affect the rotation base either. I painted my black to match the other components
on my roof. Great little device. Works very well.
I didn't want to scrape off the old caulk. So, I cut the three legs of the old black cover. There
was just enough pipe above the... old shield to fasten the Cyclone. I didn't have to mess with
We won't know until next week how much better our motorhome will smell. I just hope a low
branch doesn't attack it.
After mounting both units I was on the roof installing a bathroom fan vent cover and noticed that the black tank vent was full of ...moisture. Although I have not used the RV for camping yet, I am sure the odor will be eliminated completely.
Will this help eliminate smells coming from my roof top air conditioner of my RV?

When I run the air conditioner of our trailer for extended periods of time on hot days, a very strong poop smell comes out of the air conditioning unit. The smell starts gradually until it's fully emitting poop odours non stop unless you turn it off. It doesn't happen when the same fan is running - just the air conditioner. We've done everything! Ran hoses down each vent pipe. Took apart roof top unit to ensure nothing has died in there, poured cleaning products into septic tank....and more. Nothing is working and I'm getting so frustrated. Do you think this product could be the solution to my problem?
It sounds like the plumbing vent on the roof of your RV might be placed right next to your air conditioner. When a standard plumbing vent is placed next to a rooftop A/C it is not uncommon for the fumes to be sucked in by the A/C when turned on. A product like the Cyclone Sewer vent or 360 Siphon is helpful in redirecting the fumes away but also keeps the fumes from building in the holding tank as well.
Another thing to look at are your house batteries, 'boiled batteries' can cause a sulfur like smell.

They are a standard size, yes, and the Cyclone is designed to work with any RV holding tank vent opening.
