Can I use a portable air tank as a compressor tank?

by Alex
(Colorado Springs, CO. USA )

I have a small compressor motor that works fine for a brad nailer, but has no tank to run, say, an air chisel. I would like to know if I can attach a portable air tank to that compressor and use it in my workshop as a regular 3 gallon compressor?

________________
Simple answer Alex is yes, you can. You need to be sure that the tank you use is rated for the pressure your compressor will pump into it.

If you look under the Tank section on the sitemap page, you will find more info about this.

Cheers,

Bill

Condensate valve

by John Varga
(Plantation, Florida)

I have a twin tank Hitachi EC 12 hanging in my attic from the roof rafters. It's a pain to go up there and manually drain the condensate from the lower tank. Can you recommend an ecconomical drain valve. I prefer a 1/4" npt valve and 120vac

John, the advertisers on my auto drain page on this site will be happy to help you with your new auto drain valve needs.

However, why not just plumb the drain down to the counter level and add a small valve there? Then, when you need to drain the tank, open the valve where it is convenient to do so?

An auto drain will, of course, do just that, and that takes the responsibility out of the hands of someone and makes the tank draining automatic.

Cheers,

Bill

confused
by: Jim

I have a 30 gal tank on my compressor that I run at 150 PSI. I have a small 3 gal tank I want to use to fill tires in the field. When I hook it up to my big tank with the compressor running the big tanks goes up to 150 PSI but the small one only goes to 35 PSI. I am absolutely confused. Even if I leave them both hooked up together for a few minuets to equalize the small tank wont go any higher. What am I missing Bill?

Good topic to start a new thread Jim. Do that if you would, and while you do that, ponder, is the gauge on the small tank working?

When your tank is larger and fully charged, you have more air pre-compressed at your high pressure set point ready to be used.

If your air consumption is less than your compressor is able to deliver, you will have lots of air for your air tool.

If your application draws more compressed air than your air compressor can produce, you will have more time to do work with a larger tank before your air pressure drops below the minimum operating pressure of your tool, and you have to wait for the compressor to catch up.

Compare a larger air tank to a larger battery. The more storage, the longer something can run before the "battery" runs down.

There is more info on this here and also here .

How long to fill up an air tank?

by Lewis

What calculation do you use to determine the amount of time to fill large receiver tanks?






Bill answers...

Hi Lewis, and thanks for writing in.

I've been asked that question a few times, and finally put up a page dedicated to it.

Click this link... Time to fill a tank.

As it says on the page, I'm no engineer so you should use the page information as a guideline, and if you need for-sure accurate info, get an engineer's advice.

Cheers,

Bill
