*A quiet **Generater.Systems** , love the dual fuel capabilities, camper is 50 amp but the adapter helps and found it still handles the load. Haven't taken a camping trip yet, that's in a couple of weeks. Will see how well it does over a long weekend.*

[@9q7a5z]

What about the construction generator used in the first video? Just as someone already alluded to, for air flow, you must have a inlet opposite the fan. The fan should be sucking the hot air out while fresh air is sucked into the box and around the generator. Good attempt as many of us diyer have attempted to quiet the beasts. Maybe one hybred design using everyone's ideas will be the answer. Keep trying! The perfect quiet box has yet to be made.

[@Amy_McFarland]

2 things, first you did not use the same generator as in part 2. Secondly, there needs to be exhaust holes for the air flow of the fan to effectively keep the generator cool. Without the exit air flow the fan is keeping hot/warm air flowing at itself, which only gets hotter the longer the generator runs. This can also overheat and stress the fan. Making a baffled air exhaust will keep the noise down, sound cannot travel around corners but air can.

[@mexicanpower544]

We have used the kzbin.infoUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y for probably 30 hours with our camper and it’s been great! The noise level is really only noticeable when running the AC and other appliances like the microwave, hair dryer, or coffee pot. It’s not huge like other ones and it has wheels so even at 90lbs, I can move it!

[@CarlosRamirez-mq1or]

This is a good idea just keep in mind the generator used prior was a predator brand which is much louder than the one you are using here. Other than that anything used to reduce generator noise with no air restrictions is a great idea. :)

[@Captainkleen]

One thing when you made the quiet box you had what looked to be a Predator standard generator louder then the inverter you used in this video we’re talking standard generator around 78 decibels and inverters are around 56 decibels. Another important item you need a vent to flow air through so the fan can pull the heat out while cross ventilation.

[@stanleyqc2244]

Thanks for the update. I'm gonna build this this weekend so we can run a radiator in our RV during the night. Let's hope it goes well :)

[@LandbergTileTV]

We used this all spring and summer camping! It works great and good luck! 👊

[@rkeithphillips8233]

Internet search reveals that GoBoard is Johns Manville’s new ultra-lightweight waterproof tile backerboard. The maker looked to its polyisocyanurate commercial roofing panels as the basis for the new product, which is lighter than cement board and can be installed in residential and light-commercial tile applications. GoBoard can be scored and cut on-site with a utility knife, and only needs to be sealed at the joints and fastener locations upon installation. Panels are priced between $25 and $28. Can't find anyone here in BC Canada that has heard of it. Looks like a great light building choice. The spec sheet I found was dated 07/2017, so must be very new.

[@AlexanderGarcia-my2qd]

I love the design the fan may have been better placed on the top to direct the noise escaping from the fan upwards just a suggestion and the same with the exhaust pipe you could have put an elbow on it and vented the exhaust upwards to reduce the noise as well. One more alteration that may be helpful as well would be to change the fan type to one of those little 20$ two way vent fans the have at wallmart to cool the box better

[@ajam4u]

This is better than the quite box without a fan. But, there are still problems with this design. The fan should be an exhaust fan, pulling the hot air out and the cool air in. Although, this not as important as the next problem. You can still keep it as an air pushing design. Second problem, the air intake should be the same square inches as the fan hole. You are trying to push a large volume of air out through a little tiny hole. Very little of the outside air is getting inside the box. It's not fully ventilated, you are pushing around hot air within the box. You need a bigger hole to get the hot air out. Side note: When the US killed Usama Bin Laden, they landed a helicopter inside a walled compound. But, they couldn't take off because the wall was preventing enough air flow to lift the helicopter up. This is the same concept with a tiny hole on this design. It is preventing enough air flow. It's like trying to run a marathon breathing through a straw. This is also hard on the fan motor. This will shorten the fans expected life-span. Third, it needs to be opposite the fan so the air flows across the generator. And for the engine exhaust, it's some distance from that same tiny hole. On your previous video you had a different generator where you attached an extension pipe on the muffler exhaust. You need to do the same with this generator to get the hot air and the carbon monoxide, CO2 out. There is now less oxygen within the box for the carb to take in. It's not running as efficiently as it could be.

[@Random-rt5ec]

Excellent job works great at reducing the sound. Plus it provides a protective cover to keep the weather off of your generator.

[@greggarrot8132]

I would use a 12-volt Automotive radiator or oil cooler fan for ventilation if your generator has a 12 volt power Supply because they're cheap very efficient way more CFM then a regular fan use little power weather resistant. I personally put a baffle wall a little bigger then the fan with air gaps on each side between the generator and the fan so sound won't travel directly out the fan it hits the baffle wall first and did the same with the fresh air Inlet .

[@patrickmckowen2999]

Oh, and I also got a smaller and quieter generator! :>) Still works good! That is good as that is the size/style of genny I will get. Thx for the update vid. Cheers

[@61spindrift]

Wow! Its a magic box! Simply put box over generator....and presto!!! Generator gets smaller! Joking aside, even though myself and most everyone else joked about your box, I applaud you on your efforts of at least "trying". Better than my attempt (which was zero) and probably most everyone else. My father taught me to "at least try" as it is better than not doing anything.

[@LandbergTileTV]

I have been using this box a few times a year (15-20 days of use). Runs my genny cool and quiet. kzbin.info/www/bejne/o5m1fIKIh5WMb6s kzbin.info/www/bejne/j2XQlpqIq6yrZ68

[@hermanboyd3367]

Very nice I'm not an expert but, I was told by an engineer fan should blow air out of the box. And have same size entrance hole for air. Also you can deflect air intake and exhaust to help lower sound. One again Very nice.

[@jamesdewer]

Concise, effective post. To the point and intelligent presentation. Before and after.

[@-WolfMan-]

You could defeat most of your alterations simply by making the box Bigger. Just add a small vent to allow some air flow. You don't need much. To make the box quieter still, you can glue inside some sound proof studio foam. Half inch 12x12 squares will do. If you want the cheap version, just glue in some styrofoam egg crate carton for good sound diffusion. You can also make your own sound suppressor (muffler) from an old oil filter to attach to the exhaust as well. Most of these things won't change the overall weight at all. Alot of options!

[@rjostusa]

Two ways to handle noise: deflect or absorb. Hard sidewalls of your box interior reflect sound waves, so they come out of any opening with force. Analogy of sound waves: like a bucket full of water; Small hole = stream shoots far. Large hole = more water but less force. Use reflecting or absorbing material for additional control. Bose figured out amplification. You're doing the opposite in reduction of the wave! Ever see egg-crate material in a sound recording booth? Both absorbing and diffusing the sound wave. Good luck!

[@Mrcrowley1967]

Hey cool works good and adding fan did not allow for more noise . I was thinking about designing one for my couch bus conversion I am planning I have 6000 watt home lite with Yamaha engine still kinda loud I could use this concept thanks

[@deckgun31]

@@Mrcrowley1967 Did you ever build a box? If so, how did it turn out? TY

[@Random-rt5ec]

Awesome video - Your sound box works really well.

[@teacherstudentwifemom7178]

I wish I would have seen this video before I used plywood. I built something similar but it is HEAVY. I have the same exact generator. Haven’t tested it yet. I have an 8” inlet fan with a 4” outlet with no fan.

[@MrDandan170]

if anything you gave everybody a good base for starting their own box , heat rises so maybe sit it on a board base for cool air to come up from the bottom and holes in the top for heat to escape ... the fan would help but a hole or three on the top would help, that GoBoard is something ill look into for sure , where im at Security will be more important than the db level , thanks for posting this

[@LandbergTileTV]

Thanks for watching and thanks for the input!

[@alphaviews4639]

Dude you are scamming us. this is an inverter generator totally different from the first one

[@ApolloTheDerg]

It’s a loud motor in a box. What more do you want

[@jefft022]

So how much did you lose?

[@Intellistan]

I mean... either it's pulling a vacuum or pressurizing the box, air flow is a 2 opening event so... a few more tweaks and it will be there

[@incacondor8683]

thanks for sharing. The fan is a great addition to keep air circulating but it would be best if the fan pulls air out rather than in.

[@LandbergTileTV]

Thanks for watching! We figured the fan blowing on the cylinder would be best and it's working out great so far! Maybe a second fan to pull air in as well.

[@tgriebe]

Sound travels in a straight line, so you can add a second overlapping "roof" over the fan with some absorptive material on the underside to prevent sound from blasting out the fan grille. You want to use lightly compressed fiberglass like a car under hood absorber is made from.

[@dm.2023]

That's better than version 1 but the fan doesn't actually do a lot because there's no exhaust port. Have you ever put your hand over the air intake on a hair dryer? Same thing. You gotta allow the air to get out of the box as once the fan has created positive air pressure inside the box to the extent that the fan can push there's no more air movement other than that small hole for the cables. Port the box!

[@rickylloyd2010]

This needs more air flow u going to just junk that generator

[@rosabeha8121]

Very good box! If I see correctly, the big fan blows into the box. Where can the hot air get out again? And what temperature comes out of the box, e.g. after 30 minutes at half load?

[@carlosfernandez1]

Muy bueno. Good project. Very practical easy and not expensive. Thank you for shearing.

[@mikekennedy3173]

Thank you for your video. Appreciate it

[@ADAdams-wn1nc]

What happened to the construction generator? Did you burn it up without any vents to keep it cool?

[@jaywealthmechanics9285]

Great job👍. I will do mine also.

[@rcboals]

I have enjoyed all your videos. You are the reason I bought the Firman Whisper Series 3200W Peak / 2900W Gas Inverter Generator from Costco. Do you think the new fan is over kill with this Firman? The Firman is pretty quiet on its own but I thought if I can build a light weight box like yours why not, since it wouldn't take up any more room if it sitting over the Firman.

[@LandbergTileTV]

I think you should for sure make a box with a fan, it helps out so much! I camp at places like Yosemite and these camp grounds frown on generator noise. I'm happy you are enjoying my videos! I appreciate the kind words.

[@DaveRogers583]

Even with that fan it's a fire hazard. You need to dispel the hot air and draw cool fresh air. You need a intake and outlet. It's likely that you are overheating your generator and evaporating the gasoline. Gasoline fumes are extremely flammable. Even with this fan you have created a dangerous situation. If you're lucky the generator will overheat and suffer serious mechanical failure before the evaporated gasoline fumes ignite. I would mount a covered vent fan on the the top of the box to draw the hot air out and put a louvered vent on the side nearest the air filter.

[@LandbergTileTV]

Thanks for the info! I'll definitely take that into consideration. I'll be building a newer larger/multiple fan box very soon here.

[@jmrichsonsr]

It taes spark to ignite gasoline vapor. Ambient heat will not ignite it.

[@BlueLuvbby]

What if I put 1 fan facing in and 1 facing out? I love it tho VERY QUITE

[@LandbergTileTV]

That would work also and give it more air flow 👊

[@xraykadiddlehopper8067]

Ding ding ding!! we have a winner. Common sense.

[@rollercoaster55]

A more efficient design is to suck air out rather than blowing air in to hit the engine. You want to suck out hot air which will result in pulling in cold air. But you need an air duct on the other side to accomplish this good air flow. Otherwise your fan will be straining to push/pull small amounts of air as the pressure increases inside but there's no way for air to come in; the higher the pressure gets, the less air will be pushed/pulled. It may run without an opposing air duct but without this the life of your generator will be greatly reduced. Otherwise, good job and good design. That assumes the boarding is fire-proof and won't burn up. Drywall is good for that.

[@LandbergTileTV]

Yes sir, great ideas and yes, fiberglass made board with heat resistant spray paint.

[@rollercoaster55]

@@LandbergTileTV Oh I forgot, there's another product called Safe and Sound sound proofing that's fireproof. Also, having 2 fans would be optimal. One sucks hot air off the top, one pulls in cold air from the bottom (not in line of sight) so you maximize the air flow without dead space.

[@shantor100]

Air flow needs an out, not just an in

[@AlexanderGarcia-my2qd]

I live in a rv parked on the side street in a residential neighborhood and I need power at night but don't want to be a nuisance to the neighborhood so I'll definitely be looking to make one of these to use on a little 900 Watt Baja inverter generator . Do you know roughly how much the materials to build this was?

[@suburbanpainter4596]

Do you think i need a fan for my box if im running in below freezing temps and have an exhaust hose leading out plus a few holes drilled out for air?

[@LandbergTileTV]

A fan is always recommended 👊

[@charleswesley9907]

I see air in but no air out .There has to be a cooling air exhaust as well as an engine exhaust .

[@xraykadiddlehopper8067]

That was my first thoughts too. Needs cool in hot out or bye bye generator.

[@Kharizmah]

2:01 was exhaust for air out

[@Boobar]

I just completed your box build for my Firman 1600/2000 and have 2 smaller, lower flow “computer” usb powered fans, one on each side. I’m getting temp readings of 115 degrees inside the box. (Mid box- side of generator). Wondering what a tolerable temp is without destroying the generator and if I need higher flow fan?

[@LandbergTileTV]

i run my firman under it, I never have had a problem. I have a few videos on it.

[@Boobar]

@@LandbergTileTV Update- I added an 8" 120v fan to the front of my box today and huge difference in temperature. I now max out at 82 degrees in the box. So, thanks for your input, big fan blowing in, big difference in temp!!

One question is the another name for the GoBoard I live in Canada and Lowe's and Home Depot have no item , I looked on line nope, so can you recommend something similar. Take care Gary

[@LandbergTileTV]

Yes, similar board is Durock foam tile backerboard, Schluter Kerdi board or Wedi board (backerboards). These boards are a little more expensive, but very light weight and can work with this application.

[@b-radfrommalibu]

I like how you have a different generator than in the first video without the fan. I was wondering how long it would take to burn up that generator with no ventilation. I'm guessing 1 day. Also looks like the smaller model from harbor freight is a lot quieter than the one you burned up. You could have avoided both videos if you would have bought a Honda or Yamaha.

[@LandbergTileTV]

I still have the prediator. It's used for work and running power tools only as it is way too loud for the camp grounds I stay at. I have three genny's and they all run great! Thanks Erik

[@kingscorpio5489]

Any overheating problems?

[@LandbergTileTV]

None so far.

[@garynistico9545]

Great sound box. I noticed the generator is different than the original video, was there a reason why and would the fan work well with the bigger one, just curious. Thanks Gary

[@LandbergTileTV]

Thanks Gary! I own three generators, 2 Predators (4000w and 2000w inverter) as well as a 3200w inverter Firman. Yes, the box and fan does work with the 4000 watt, but it does get hot after a few hours. The inverter 2000 watt generator and the Firman 3200 watt inverter generator work great for this box! Here is my latest video testing the quiet box with my new Firman: kzbin.info/www/bejne/j2XQlpqIq6yrZ68

[@Brookside975]

You are creative! Hope you still check the temps inside the box occasionally to make sure it is not getting too hot. I noticed the gen is different than in the other video. Did something happen to it or do you just have two? Cheers.

[@LandbergTileTV]

Hi Steven, I don't run my generators in the box for more than a few hours at a time. I usually only use the box when camping. I still have the Predator 4000 in my trailer for camping, the inverter 2000 for job sites and currently testing the Firman inverter gen. The 4000 has almost 100 hours on it running under the quiet box and no problems so far!

[@jcfra420]

Better to think of a computer man. The fan is a good idea, but should be pointed out. You want to push the heat out.

[@ainttakenanyshit]

Although a GOOD idea to fan IN outside air, you are STILL limiting the available cooling by not also using another fan for EXHAUSTING the air drawn in by the first fan... Right now all you are doing is moving around HOT air limited by only the small, partial holes for cables etc.... Unless you draw out the hot air with a fan exhausting, you are really just pissing in the wind....... ;-)

[@AlexanderGarcia-my2qd]

This can be done with those little two way vent fans that are 20$ at wallmart

[@sanseiryu]

You just created a convection oven. If you are going have the fan blowing in, you need a grille to let hot air out. Better to have the fan blowing hot air out and a grille opposite to let fresh cool air into the box. Fan doesn't even have to be that large, just need the fresh air grille large enough for unrestricted flow. I would build a platform to support the generator that the box can fit over. Use fiberglass insulation to deaden the sound going toward the ground. Having the generator on hard pavement only amplifies the noise and resonance.

[@DrewDeGraff]

I cannot find any of the lightweight "backerboard" at either lowes or hd in NC..but I did notice this foam board insulation. i'm wondering if it would work as well, and it's only $12 a sheet. www.lowes.com/pd/Rmax-R-Matte-Plus-3-R3-2-Faced-Polyisocyanurate-Foam-Board-Insulation-Common-0-5-in-x-4-ft-x-8-ft-Actual-0-5-in-x-4-ft-x-8-ft/3014172

[@andreww7857]

I don’t have any practical experience, I confess, but intuitively this isn’t going to work. You can tell me that it’s works flawlessly but sorry I cant believe it. The muffling is created by the original thick-walled box that essentially completely encloses the generator. Of course a fan was added and so was a giant hole in the box. And another commenter is correct that the hole was for inflow and there was nothing for outflow. Not to mention the fact that when you need the generator, you need electricity and with the fan, you wasted 200-300 watts powering the fan. Nope....

[@TheWulff82]

This still won't work...

[@LandbergTileTV]

This was almost a 3 year update on the box, using it 6-8 times per year about 1 week daily use per time. kzbin.info/www/bejne/o5m1fIKIh5WMb6s

[@TheWulff82]

Good luck! I've made numerous enclosures for various types of generators. Your carb is only getting hot air. More gas consumption and higher running temp. Your generator won't last long. For occassional use, this will work I guess but a lot of effort for occasional. You had to add a fan because it was choking and stalling then engine 😉. You can just lean plywood against it to get that quiet. If you can achieve 45 decibels or less at 10 ft, we'll be impressed.
