My air compressor motor or maybe pressure switch died and so I’m looking to upgrade stuff. I have a new 220V outlet ready and can just replace the motor and switch and be done, or also get a new dual stage pump since I’ve heard they are a bit quieter. Anyone with real world experience can comment on the noise difference between single stage and dual stage?
 
I have a 2' stage Saylor Beal..
Seems to have gotten noisier as it aged

Some cheap compressor heads seem too make a lot of noise.

My blunder was buying a piston v. A rotary screw compressor. Screws are much quieter.

Ha, would love one of those but I don’t need that much air.
 
Rotory not as high psi also .

You want to quiet reg setup read up on my compressor builds i did . Everyone who hears my 19cfm @ 175psi IR pump is amazed how quiet it is.

shop air system / upgrade yet again . . .

so the new shop I got with the house has a colman powermate black max air comp in there . its a 6.5hp 2 stage unit with 80 gal tank . online specs show 15cfm @ 100psi and 13cfm @ 175psi . so the other day I fired it off and the tank started with 50 psi in there . after over a min the tank...

I know when I upgraded my compressor it was a huge difference. Went from '5hp, oil -less'. To actual 5hp, oiled. Runs at half the rpm which was a big difference, and then I played w/ intake mufflers, which also made a difference.
 
I remember when I built my compressor from a couple of different ones I fabricated an intake manifold that did a T and put a couple of filter/mufflers on it. It was noticeably quieter than the original straight-shot with a foam filter setup. I think there's a lot of gain to be had with intakes.

Absolutely night and day noise difference between a small displacement, high-rpm "oil-less" compressor and a dual piston slower moving machine. I can't speak for the noise difference between a twin cylinder and a dual-stage, though. I thought that was more about efficiency and reliability because you don't have to heat/compress the air as much in a single step. Plus, it's typically more tank pressure, which is more stored energy.

Maybe I can try something like a TEE and extra mufflers.
 
That is all it is, tied to the intake...I want to make one out of an 24 x 24 x6 electrical enclosure and foam and mount it on the wall behind the tank.

It's well past the 15th..
Any ambition to take some pictures yet?
:D
 
ok, I finally got out there and took a couple of pics. I realized one of the ends cracked at some point so decided it was a good time to take some pics, while i made a new end.

Basically you take 2 4" end caps, cut holes in them and run some pvc through thusly.

Attach them to ea end of a 4" pvc pipe

Glue it all together w/ your choice of glue/silicone/whatever, snd you've built yourself a pvc muffler.

I saw a couple of people that put some packing in but think that's a really bad idea - even with a filter and didn't feel I needed it on mine.
