At my local Fleet Farm store they sell the .5" thick rubber horse stall mats in 3'x4' sections at around $20.00 per section. Work great as pads for generators.
Great Video. Pretty fair all in all. My brother started Zombie Box. It has been awesome to see the response. As for the cost, he has wanted to get the price down but there isn't really a way to do that until he has a factory that is stamping them out at a hundred a day. He doesn't have big profit margins. Getting the Patent was genius though. Eventually someone like Generac or Kohler is going to need to buy him because they make such loud generators. A bit of warning though, If you have anything around your generator without a big ol' fan to suck out the heat, you are going to burn it down. Trust me, Dave has researched it and thoroughly tested the concepts and has some pretty good cautionary tales.
@@meekinsstevenmeekins yeah, if there's enough air flow with just vents then it doesn't stop any of the sound. He found that you have to have a really big fan to get the displacement high enough to make sure that it pulls out all the heat and then the vents big enough to not slow it down so it's a balance of vent sizing and fan sizing.
Jim Leedy, that’s awesome! I’m curious if there’s a rule of thumb on how many CFM would be required for a homemade enclosure? Not everyone can afford a ZombieBox (as much as we’d like to), so it’d be nice to know what size fan to get to not destroy my generator or burn down the enclosure 🙃
@@InfinityCleaning yeah, I'm not sure what the actual CFM is but it's kind of like those attic vent fans that you get from home Depot so I believe they're moving a thousand CFM or more. The trick is in the double-walled panels where the air intake is because if those are straight through vents then all of the noise escapes that way. So you got to keep the sound in and let the air in and out. It can be done on your own but to get the 15 or so DB reduction it's probably going to be a pretty big project. The 5-year plan is to get something like a appliance manufacturer or somebody to start stamping them out to get the cost where it needs to be which is about half of where it is now but at the scale he's at it is what it is.
It's a use case issue. In certain circumstances the generator was selected based on application rather than price. You'd be surprised at the range of field generators in need of baffling.
mount it below grade and use a bathroom vent fan on the plywood/styrofoam sandwich cover. Use 4" PVC for air inlets, with 90=deg elbows. You won't even hear it.
I went with the zombie box last year. So far I had no outage to use it under long term. I tested it this fall and it seem to work great. It has the big powerful fan at the top that kept the air flow moving in and out of the box. I ran it with a wireless temperature gauge so I can monitor if heat was building up inside. The temps were in the mid 70F. The noise control was a big plus. I wanted something that I can setup when needed in the middle of a New England winter in a emergency. Hopefully it will still impress me when I will have a real need for it.
A question to bravoone17, is the back and front single wall and the sides double wall ( looks like 2-3"thick) with offset air passages forcing the intake air through a baffle of sorts? that would make like a muffler having the noise have to travel up or down through 2 vent spots. Thanks, Dave in Oregon
Thinking of going with one of these for my Westinghouse 12 KW dual fuel standby generator. The noise reduction would be worth the cost of the extra large unit for my big generator. Currently running it in my garage with everything plummed outside, but with the MIL Apartment above the garage it's hard to be in the apartment with the generator running below.
The company that makes the Zombie Box has 9 employees and makes each box by hand. I tried to order one thinking they had stock but they told me it might take 5 months. It’s a great product but you’ll have to wait for it.
Hi! We need a box for our generator that 1. Dampens noise and 2. Keeps dust out. We take ours to Burning Man and dust is a huge problem. Any suggestions?
Noise control is an important part of any gen. enclosure. Typically you use an MLV (mass loaded vinyl) as a barrier to noise transmission and on top of that a fibrous or blanket to attenuate sound. That cost $$ to do it right. These materials are readily available. When I made inquiries at Zombie box they refused to discuss this stating that the info was proprietary. The box is expensive and attractive and it made me think they used inferior materials. For that reason I looked elsewhere and there is at least one youtube video that supports my concerns.
Hello, we just bought a Suncast enclosure 70 cubic feet . Will be using an exhaust fan plus a few vents. My question is what can i use inside for sound damping that isn't crazy expensive? The enclosure itself would deaden some of the noise but im looking for better and something that would be easy installed? Also bought a Champion 9375 starting/7500 running. Im from Nova Scotia and winter are harsh. Great video content cheers
Thanks! I know what you mean about winters being harsh. I’m on the east coast of Canada as well! What I would use inside would be the same sound deafening material you would place under a hood of a vehicle. Look for vehicle self adhesive sound deadening material and you will easily find what you’re looking for. The reason I would go with that stuff if because of it’s high resistance to heat. Thanks for watching! Cheers!
Hi I had a Nutec box built for my generator. It obviously has breathing gaps on both ends, but what kind of soundproof tiling can I fit it out with and would it make a difference?
Hey bro. Nice video. Can you do a video on how to make a truck apu much quiet? I'm sure most over the truckers would love a quiet truck apu. Just sharing my thoughts . Thanks 😊
I'm buying a 22kw Genaric natural gas generator. I should have it installed in a few weeks. Now I can be a total jerk to my neighbors. They are already are going to be pissed off that my whole house including my hot tub will be running. But, I like my neighbors and my neighbors like me. This generator is 66db. Any way to quiet this thing down?
Aren’t those generators already in a built in enclosure? I believe you’re talking about a standby generator right? If that’s the case; their already pretty quiet and I’m sure you’ll be happy with it!
Good advice, but you need to add advice on a foundation for the generator, perhaps cement one-foot paving squares that you placed on level ground on top of rubber a mat.
I installed a Generac whole home unit, I just made a 30”x48” square out of 2x4’s from Home Depot, nailed them together, leveled the dirt underneath and dumped in a few bags of quick setting redimix, hosed with water while stirring to a “pancake batter” consistency, waited 2 days and Viola ! Has held up perfectly for years
At minute 6:29 your video shows an image saying the gentent generator tent is suitable for fully encased inverter generators and not for the open frame ones. On Amazon they state exactly the opposite. Can you please double check your source? So far I couldn't find any suitable tent like solution for fully encased inverter generators
That is an option, but most of those generators are going to be more than the price of a crappy noisy generator and a zombie box. The nice thing of a zombie box is it's galvanized metal that is probably going to last 15 years sitting outside so depending on how much you use your generator it will out live three or four replacements.
It’s also really hard to find an inverter genny larger than 5kw or so. Tough to backup your whole house (or even just the necessities like furnace, well pump, hot water, fridge, etc) on something that small
I agree. Back in our younger days, my late wife and I would take our two small boys camping a few times. We took along a tent that would accommodate us all plus a Coleman lantern and the other necessities. A fire pit was provided and the distance between the other campers at the camp ground was pretty good for the privacy. This was back in the 60's when motor homes were not in vogue at the time. It was at Yosemite when the camp ground was more isolated then than it is today with it's many motor homes.. I get a kick out of my niece when she and her husband say they went camping. They would arrive in a humongous motor home and I guess that they thought that they were roughing it while living out of that motor home. That damn thing has just as many accommodations as my house does, maybe more.
A bit ..? A Little..? common. You won't do any testing to quantify the noise reduction .This information is worthless nonsense. What are the changes in decibel readings!!!

Zombie Box is a great unit and idea...congrats! Heat from the generator itself won't be dissipated through the many vents alone..?

I was looking for the zombie box for years. This box answer my question thank you I really appreciate 😊 👍
This is the best report on this topic on the internet. Great work.
Thank you for the current information about quiet. I never thought about a quiet box.
I live in a subdivision where all of the homes are very close together so sound abatement is a must! Thanks for the info.
I live in a subdivision with utilities. Out of 8760 hours a year we average ~1.5 hrs/yr of outages. 99.983% reliability.
For some reason I can't quite see myself spending four times what my generator cost, just to buy a box to put it in.
It's a use case issue. In certain circumstances the generator was selected based on application rather than price. You'd be surprised at the range of field generators in need of baffling.
I just strapped a plywood to the top of my eu7000is, works perfect .
@DanielGonzalez-un6rz do you have a video or picture?

You could build a house in under 5 months

I just ordered Noico 80mm sound deadening from Amazon. Hoping this works, its expensive. Thanks
Rockwool Safe 'n Sound Insulation, at Lowes/depot. Fireproof and greatly deadens sound.
Great video
Thank you for the great information and links. 👍👍
What kind and how much insulation does the zoom be box use
Hi
I had a Nutec box built for my generator. It obviously has breathing gaps on both ends, but what kind of soundproof tiling can I fit it out with and would it make a difference?

Thanks for this very useful information.
I bought a Zombie box not knowing what it was, I thought you were supposed to get inside for protection in case of a Zombie attack
Great info!

@@soundproofguide lol, no, generacs are definitely loud. Extremely useful, but loud and house-shaking.

I love this Guide
Mate, great video,, thank you so much, really helpful
I got one to live inside to avoid sounds of the generator but it's a bit small.
Thanks!

GenTent makes models for both Inverter generators and frame generators. He just happened to take a picture of the inverter model.
Great video!!
Awesome
Where I can buy it? I don’t find it anywhere
locate the search box on the computer
My "Silent" diesel generator is one of the noisiest things I have ever owned... Beware marketing BS.
You get what you pay for. Cheap = noisy. Can't go wrong with Honda
@@cayrick I have three generators. The Honda is the smallest and the noisiest. It does, however, start on the first pull every time.
For the price of that Zombie box, I'd just put that money into a better enclosed (non-open frame) Inverter generator.
That is an option, but most of those generators are going to be more than the price of a crappy noisy generator and a zombie box.

@@jimleedy8029 Have you looked at the prices of those Zombie Boxes? Your statement is correct only for a cheap DIY box.
A permit? What kind of world do you live in?
The Texas HOAs can be brutal in some areas.
The zombie boxes cost more than the generators themselves? Absolutely way overpriced for what they are .
I do agree they are expensive. I’ll get my hands on one someday and see how well they really work! 😊
Number 2 was the only real box
Unless I missed it hearing each application would have been beneficial.
A permit? Where the hell do you live? Screw that place
Note: The tent type quieter may be vulnerable to strong blowing wind.
Never place a generator in a box that has reflective layers in its inside walls. Except if you live in Antarctica.
Why? It's not an issue if there's a fan cooling it off like the zombie box.
better to have too much generator than too little. Starting air conditioners requires extra capacity., at least double.
Use a soft starter
you just dont tell them it was enclosed, problem solved
Zombie box extermly over priced.. U can do similiar thing for 20 % of the price
Agreed!
Camping + generator = Not really camping
Kinda have to agree with you there. 😉
I agree. Back in our younger days, my late wife and I would take our two small boys camping a few times.
