This will work for Portable Generator..... only need portable a/c to help cool Down during Summer 👍👍

It appears to be well made. Westinghouse recommends a 5 hour break in period at 50% load. The included picture was taken during this break in period. I tested it with gas and then propane, and it ran well. I haven't yet tested it under full load, but will update this review if problems are encountered.

Thanks this is what I was thinking type of deal but didn’t seem to do a whole bunch for the work. It would have been nice to a noise meter during the video

nOW THAT ONE WORKS. iMPRESSED! iT'S ABOUT TIME SOMEONE MADE ONE THAT WORKED. tHAT'S A DAMN NOISY GENERATOR TOO. wHAT ABOUT INTAKE PORT AND COOLING. oops capsl;ock was on. not intended. typing with one hand.

Good helper

Still very loud

Hello.Is it possible to be used in a Van? If we consider noise and flamable.

No DB results or comparisons? This video is just like all the others, not very informative

THAT LOOKS LIKE A OLD FRIDGE... GREAT IDEA

I don't care what anyone says. These boxes are going to make these generators run hot as hell...

Best generator box I've ever seen designed. You should really consider on getting it patent. These forsure will sale lots of people want these quite boxes and it hasn't been invented yet.

A little bit of explanation would be great...

I have had this unit for almost a year now◈◈>share4.photo/F3kGenerator?ν I use it to power my toyhauler RV when I'm out in the back country. I purchased this to replace a beast of a Champion unit that was just too loud. I can also lift this into my truck, but the Champion required 2 people. This Firman unit is absolutely awesome. It powers my RV including the Air Conditioning with ease, and it is super quiet! I honestly can't get over how quiet it is.unning air this unit has powered 2 full size RVs at the same time. It also has a battery charger kit that I used when my car battery died. I bought it at Costco so I am protected by Firman and Costco so I know I will get years of service out of this unit. Easy to start, easy on gas and more than enough for the job! 5 Stars! The best part is the price was literally 1/3 of the cost of a similar Honda so my camping buddies now hang their head in shame.

Does it overheat ?

The only improvements would be possibly some absorbing foam inside intake and exhaust baffle sections. Bitumen tape/flashing/deadener only adds mass to panels. You could also consider a diffuser or cowl to direct sound down over the exhaust pipe exit but not sure how effective that may be. Otherwise a clearly effective design and far better than a lot of the poorly thought out boxes on KZbin. With the intake fan blowing straight over the generator, it probably runs cooler than open air too.

Are both fans blowing in? Or is one blowing out?

felicitaciones donde se pueden conseguir planos

How much to build me a baffle box for a 3400 dual Champion generator. I want to put one on my semi truck to use it as my Apu system

Can you please tell what the size and name is of the hose you used on your exhaust...???

Its better I bought a water cooled generator. Because I want as quite as I can get it also.

The best! Very impressive piece of work. Can I get the plan to build this like yours...Thanks.

Wow, nice. Any chance you sell these? I'm an old grandma and don't know how to build things but really need this for my tiny house. Thanks,T

we need a diy guide plz!

the honda 3000 out of the box sounds lower then that generater in the box.

That is actually pretty good !!!

Brilliant!!!!!! This is the best silencer I found. Please make a how to and you will get a million views!

Where did you get that exhaust line? I'm building one of these buggers.

Nice box. I was thinking of building a box with similar channels but not necessarily in line with the exhaust. Another thing is I plan to leave the bottom open and direct some of the noise in to the ground. Saw another guy just lay plywood angled towards the ground and it seemed to work well.

Great enclosure design, if you are building a baffle enclosure this is absolutely the best video to reference. Only thing I would add is a thermometer system, so you can check on actual run temperatures easily during an outage. A basic wireless "weather station" or wireless outdoor thermometer would probably be cheap, and work well enough depending on how far away your genset is

I like it. Dryer vent with sound deadning material inside it it the way I'll change it.

I think that if a rough / tiled surface were applied at the opposite end of the ducts, an additional noise reduction would ensue. I also think that the mass of the materials in the box plays a role in the noise dampening. I would also experiment with resonance frequencies too. Let's say that we have a resonance frequency measured. Then we added a box with the same resonance frequency as the measured space. That would result in a noise cancellation. I checked it out and it is called a Helmholtz resonator.

Nice job with the baffling and chambers.

Air cooled and does not overheat inside that box, I wonder if they supposed to operate at higher temperatures

Congratulations sir! You are the first one to succeed and have done the impossible!! Bad ass!

I agree, it's the best so far.

Hello. What would you charge to build me this for my honda eu 2000I Inverter generator?

*Best one I've seen so far on KZbin.* Nobody else seems to understand the theory of channeling and chambering the air intake/exhaust ports. Sound waves likes to travel in a straight line. Once you disrupt that straight line, you create a ricochet effect with the sound waves. And with the sound dampening material you have in there, it just absorbs the trapped sound waves. For the purposes we're looking for, you have a significant decrease in decibels using this method. I learned this building speaker boxes back in the day and you used a VERY similar concept. The box design by itself is excellent work, and the temperature switch made it fucking genius! Slap a couple of coats of deck sealer on it for wet weather and some wheels and you're really in the game. I wish you had the plans drawn up. And by the way if anybody is planning to build this, the best wood should be as non-resonant as possible. Generally, that means either dense plywood (birch ply is good) or MDF fiberboard. 1" thick. You can't lose!

I did not really build it to be utilized in the summer and hot temps. I would not be concerned about using it in hotter temps for short durations, but I wouldn't want to run it for hours this way.

does this ger very hot in the summer?

Could you post the plans for building the quiet box. This is the best one I've seen. You should be very proud...

Is convoluted foam better than styrofoam

Cool I needed ideas my generator room is 4 x8

ain't the foam flammable

You are a genius!!

Nice Job!!!

what is the electric looking box close to the exaust area?

Would be nice to see a video detailing the box.
