So we are looking at moving into a new place here in town soon. Moving from a house to a large upstairs apartment that is cheaper and has more space. My question is who makes a decent quiet compressor. My current one is fairly loud and I don't want to bother people downstairs. Just wanting to see what everybody uses.

Good quiet compressor?

On option, if you're concerned about noise, is going w/ a CO2 setup. I'm thinking about going this route as my wife & I are moving into an apartment in late November, and my current compressor is finally starting to show its age.

I have always wondered how cost effective a scuba tank might be. I can't remember the cost to fill one. And at 3000 p.s.i. full how long it would last. Doing that calculation is above my pay grade. Anybody know?

Well...spraying at about 5-20psi...guess we have to figure out converting PSI to pounds per minute and the flow?
I may have an engineer who knows these things.
Found this online calulator

fired it up and this hit...
:huh: :stinker

I think that the volume of air might be another variable. INAE (I'm not an engineer)
Toss it to your engineer with a Bagel and put him/her to work. They love to show what they know (and that's great for the rest of us).
Sorry for the hijack nerdling,

I've seen it posted on other forums that depending on how much you paint, a smaller bottle should last you several months if you do a decent amount of painting.
And yes, the volume of the cylinder will definitely determine how long it lasts.

If you want silent, then look at the Silentaire line. I have a 20A and I cannot hear it running right at my feet if I am on the phone.
Not Cheap, but you could run one with a baby sleeping in the same room.

Well at a guess a std atmosphere is about 14.5 psi so at 3000 psi you have about 200 atmospheres so presumably 200 times the volume of the tank. an airbrush will use about 5 CFM at 20psi so if your tank was 2.5 cubic feet it would use 2 atmospheres a minute and your tank has 200 so thats 100 minutes or about 1.5 hrs.
Some little compressors only put out about 1 CFM a minute so you can 4x that 1.5 hour figure i suppose in that case.
I could be wrong but that is a common sense answer from someone who dosnt know what they are talking about.....ie: me
I would point out that i don't know the laws in the US but in the UK i think your house insurance would need to know as well as the fire service if you had a fully charged tank indoors as in the event of a fire it could blow the house up. :woohoo:

OK, just rattled the engineers collective cages, we'll see which one wakes up first.

There is some danger inherent to having the compressed cylinder in the house, but that would be if the valve was detached, then it essentially turns into a missile. However, since its an inert gas, there'd be no danger of an explosion from it. That's why if I had one, I'd find some way to secure it out of the way so that there'd be no danger of damage to the valve body.
If anything, the CO2 could actually help put the fire in that it could help starve the fire of oxygen by displacing any air in the immediate vicinity.

At 100 centigrade Co2 will expand by 4x. In a very hot area not necessarily in the fire itself pressure in a 3000psi tank could easily increase to 12000psi. I for one would not want that in the house. Its recommended that tanks if left for more than a month are stored empty or at less than 50psi to prevent rust. this is assuming that the tank is not alloy. As for removing the valve,,As it is most likely going to sit under someone's work bench with the air brush attached i doubt anyone is going to remove the valve after every use TBH.
I still say that inert or not, you don't want these tanks in the house.
