Compression - Show Off Your Compressor

[garandman]

We have a Craftsman Pro 27 gallon Vertical at work that has held up well. But I may want to take this back and forth to camp, and they have a horizontal 25 gallon for the same price.

Anyone prefer one or the other?

 

[veltex]

Way more compressor than I need, inherited from my brother, 7.5 horse 80 gallon

Nice 7.5HP CP Compressor. Do you have an idea of how old it is, or if the pump is original? I have a Mac Tools compressor, rebadged CP, the same as yours I think. Mine is the same as their current model anyway. I'd like to know the differences between them. Here is a pic from Mac of mine. Again, the same exact thing in different color with the same new CP or Bel Aire models.

She just arrived today, haven't even plugged it in yet. Also got some accessories ready to go. Won't have time to play with it until next week though.

Nice! What can you tell me about the fan and the cooler.

I think I hate you...

Naw, now I'm certain, I know I hate you...

They will become an after cooler.
Fan is an EBM Papst W2E200-HH86-01
Cooler is a AKG C-3560BG
I think I got both at a Zoro 30% off sale with free shipping late last fall.

Also adding an Eaton Mag Motor Starter, Hobbs Meter, Carbon Filter, Water Separator, Oil Separator, 2 regulators (for 2 different PSI lines), and a 2-1/2" 200 PSI glycerin filled gauge to each air line. Big gauges so I can easily read them without putting my glasses on. I post pictures when I am done.

Can you post a sound clip of that quincy running from a room that it is installed ? Wanted to see how loud these things are before committing...and I was told these sounds are subjective....etc etc so basically no one gives me a straight answer.

Download a sound meter app. My guess that compressor will meter at 88 dba about 3 feet away and 3 feet off the ground. Go to your stero and start turning up the sound until it's at 88dba. Now you have a reference.

That thing is beautiful! It would look superb restored!

 

[Lu-Max]

My compressor will be installed inside of a shed that is behind my shop so not sure how relevant my sound readings would be. If I measure sound levels inside of the shed it is far smaller than your garage or shop is so I don't think those measurements would be meaningful either.

Quincy has the QT-54 running very fast and hard at over 1300 rpm

They push them hard in order to achieve its rated CFM.

At that speed I would suspect it be noisy.

Sure is pretty though, nice looking compressor

Definitely post pics when all the goodies are installed

Thanks for sharing!

Used 80gal 5hp CH, that I bought from the guy a rent a hangar from. Works great!

Very similar if not an exact duplicate of an Ingersoll Rand 7.5 unit. Just did a sound test with the Ingersoll at work and from 2' away the sound rating was bumping 97 dB. At 25' away the dB was 88.
And for comparison a quiet room with computers running and no talking the dB is around 62.
Most hearing protection is needed at 82 dB for an 8 hour work day in the industry.

dam, guess back to searching....

I know the husky 60 gal and the Kobolt 60 gal is way too loud for a regular two car garage. without any enclosure or putting it outside..... though the high end Quincy would be better. just couldn't find any clips on others... if only they have those California quiet compressors that have the noise level as them @ the CFM as these and price range of the Quincy. . those sells for 3x or 4x of the Quincy..... I think..

husky

kobolt

Just because its a noisy compressor doesn't mean you can't have it. You can make them quieter. I have whatever Lowes had as a last-one-on-earth sale, 5hp -60gal usually $350 on sale for $150. The old one had just died a permanent sort of death and I needed orne now. The sale was cheaper than parts for the old one. It has the two cylinders and the wire belt cage, similar to the one pictured. Most of the operational noise appears to come from the belt cage and the air intake. And those sounds can be attenuated. Here we use the scream-over-it vs talk-over-it standard. Not precise, but gives you an idea of the reduction in noise.
In the case of our new compressor, it was way beyond screaming over it. After about six months of hoping I'd get used to it, I approached my friend the internet and found several discussions regarding compressor noise. I think I took the fixes I applied from this forum.
First was to silence the belt cage. I used some rubber sheet glued to the face of the pump-motor base to help isolate the cage from the rest of the compressor. Also a few rubber washers to isolate it from the upper support struts. I also slit some medical tubing and wrapped the bars of the cage around the perimeter of each segment so they couldn't rattle together. That went a long way towards getting the thrash out of it, but it was not enough.
I also added couple of pieces of pre-perforated angle iron covered in rubber sheet on the back of the wire cage to stiffen it and help it from flopping around. This also reduced the noise.
Finally I went after the intake noise. Supposedly breaking the straight line path of an air intake reduces noise, so I added a few elbows between the head and the air filters.
The sound level went way down. You have to raise your voice a bit to talk over it, but you can have calm conversation within a couple feet and not a screaming match.
In the very near future I'm putting some of that sound ablative foam blanket with the bumps on the wall behind it and on the soon-to-be panels that will shield it and other fixed equipment from the dust and crud of the shop.

just a quick question on getting my new craftsman 60 gal 220volt compressor]a little quieter it has a 1x3 inch square opening with a pad of some sort as the filter anyone run into this and able to modify

Just a bit of info on modifications. Some have more pros than cons but when modifying the intake for a noise correction you could alter the compressor out put results. So in other words the money you seend to get a good compressor that puts out good cfm may be deminished to what a lesser model puts out.

I'm going to have to read this one a lot closer to see if I can silence mine any more.

I had to REMOVE the belt cover to get mine inside the "closet" that I built. The closet is insulated on three sides. I put the compressor on hockey pucks and installed mufflers on the intake. The door to the closet has a built in filter and an old CH&A fan above the compressor to cool it down more. I can turn it on and have a fairly normal conversation at more than six feet away. If I turn on the CH&A fan it's a little bit noisier.

I wish I had pictures of my old compressor. It had that head and filter. I chose a regular round, pipe threaded, filter with a larger diameter than the total area of the intake holes in the head and then cut down a compressor filter adapter from the grainger catalog to fit in the space where the old filter pad went. It went a long way towards quieting that compressor as well as making it stop breathing shop dust.
I don't have the number of that adapter, but it's intent was to make an older compressor with a bolt on filter assembly take modern thread on. It originally had two bolt holes in it, but I cut one off and ground the rest down so the one remaining hole lined up with the head bolt in the middle of the filter pad depression and carved the back side of it so it would feed the compressor's intake holes. Then I gooped it up with hi temp silicone , bolted it down and left it set for a couple days, so I wouldn't get any surprises. It did require a new, longer head bolt.
I can't find the adaptor online nor in the paper catalog, but you could just use a little block of aluminum and bore and thread it appropriately.

Sounds like you have the same type of intake that I have on my pump

Hoping to score this one soon

Here's a video from another member showing the compressor running. Not my video or compressor, but I have the same compressor and did a dB test as well. Mine sounds exactly the same and dB test results were the same also. IMHO, the loudest part of this compressor is actually the Baldor motor, not the pump. A better muffler on the pump isn't going to do much for this one. I built a ventilated and sound proof closet for mine. Works great!

It’s really too bad, that is a nice looking compressor, but it just runs way to fast and has that loud annoying high speed sound.

It really is a nice "home use" compressor, but agreed that the loud high rpm whine of the motor is a pain. When I first got mine and hooked it up and ran it, I was pissed! I first assumed that most of the loudness had to be coming from the pump like everyone states about loud compressors, but mine really sounded more like the motor. I decided to take the belt off and test by running the motor only. Found that the loud whine was still there and definitely coming from the motor! Next, decided to spend another $300 on materials and build a ventilated and sound proof closet.

What I like about it is that it's the perfect size for the side wall of my two car garage with both cars parked inside, and the need for only a 30 amp breaker meant that I didn't have to upgrade my power supply! Love it now that it's in the closet! It does everything I ask of it!

Last weekend the neighbor calls me to come wire his "new" compressor. I "assumed" he bought a brand new one. He tells me over the phone its 220V and the previous owner said hook the white wire to ground, the green and black to power. I said, I'll be down in 15 minutes as that isn't right. Long story short its a 30 to 40 year old two cylinder 175psi speed-aire with a vintage 3 horsepower motor.
I rewire black to black, white to black after wrapping black tape on the wire and green becomes ground. Notice the motor is 18amps, recommend a 20amp 220volt plug and outlet. Could have been hardwired as it is line-of-sight to breaker in Panel. Go check the panel plus to wrap black tape around white wire in there, see he has a 40amp breaker to install on 10gauge wire. Tell him to exchange the 40amp for a 30amp to protect the wire when he is getting the outlet and plug.
I'm sure there will be comments on the 20amp outlet with a 30amp breaker now that I think the WHOLE thing out? Probably should have put a 20 or 25 amp breaker in to protect the TOTAL circuit?
He installed a 30 amp Dryer type outlet, it runs nice and quiet!

I would've been pissed if I bought a Quincy and got something that sounds like my $75 pancake compressor.

Lol b-body-bob, so true, I totally agree. I just couldn’t bring myself to compare a Quincy to a cheap oil-less, but hey, it does sound just like one, so sad.

yes its the same type of opening so how do I get it quieter with that setup

Do you happen to have a model number on the magnetic starter?

Nice 7.5HP CP Compressor. Do you have an idea of how old it is, or if the pump is original? I have a Mac Tools compressor, rebadged CP, the same as yours I think. Mine is the same as their current model anyway. I'd like to know the differences between them. Here is a pic from Mac of mine. Again, the same exact thing in different color with the same new CP or Bel Aire models.

Don't know much about it, but it's no older than a year or two, and unmodified as far as I know.

Hello, you're so kind and can you give me a picture of the exact reference of the head cylinder, I bought recently a compressor and have no idea on until I saw yours and is very similar, someone told me it was DeVilbiss dog Verily I'm pretty sure the imagens which is a Champion, and want to see if I can find a manual Concepts Maintenance, thank you very much collaboration you can give me.

PS and check thoroughly and has no plate where puedar see the manufacturer or brand.

It's an older Champion design, often labelled as a Dayton by Grainger.
