I have two compressor of 9.3cubic meter per min and I want to make air storage tank for them.


Giude me that how I size an air reciever tank.
Two compressor 55KW each
Operating pressure is 7.5Bar.
Flow of both compressor is 9.3 cubic meter per min.

Hello Tariq. Very nice to hear from you. Thank you for visiting my site, and for writing in.

When you plumb two compressors to one tank, you need to make sure that the air from one compressor does not flow back into the tank or out through the unloader valve of the second compressor, and vice versa.

You will plumb the discharge from the two compressors through a tee into one line, and that one line will then feed the tank.

In the line from both compressors, and before the tee, install a non-return (check valve). Then, when either of the two compressors kicks on, the air from that one has to flow to the reservoir, and not back into the other compressor.

Cheers,

Bill

Thanks for guiding me plumbing.

I want to know how much capacity of air storage tank will be if I want to attach two compressor of 9.3 cubic meter per min each with 7.5 bar.

Sorry Tariq. I'm not quite sure of the question. Is it that you want a recommendation for tank size? If so, 60-100 gallon in size would be my recommendation.

Adding extra air (tank) for us visual learners...

Can we please see a diagram or small picture depicting your lesson on plumbing / adding a slave tank (extra air tank) to an existing compressor air system?

Drewdebee... is the schematic on the Plumbing A Tank page not showing enough info?

Thanks,

How many gallon air compressor do I need?

by KS
(Portland, OR)

For a 130 gallon Auxiliary tank, how many gallon air compressor do I need?

I am looking to buy a 130 gallon auxiliary tank. For the air compressor to hook up to it and work, how many gallons does the air compressor need to be??
________________
KS, I don't know for sure what you mean by... "how many gallons does the air compressor need to be?"

Any compressor will fill any size tank. A small compressor will take longer than a big one.

Can you provide a bit more information as a comment here, so I can better understand what information you are looking for?

Cheers,

Bill

Transfer of compressed air to another tank ?

by Santiago

Compressed air tanks - unequal pressure

Compressed air tanks - unequal pressure

I was working on a Small compressor system that empties the compressed air to another tank that is used to to power an device. however my concern and question is. When the compressed air tank empties to the stand by tank how much of the pressure do you lose and what would be the best way to have the stand by tank recive the most psi from the compressed tank.

Hello there Santiago...
Unless there are leaks in the system, when air flows from one compressed air tank to another, there is not loss of pressure.

There is, however, equalization of pressure.

Please have a look at the graphic I uploaded. In it you have 100 PSI of air in one tank, and zero PSI gauge in the other. When the valve between the two tanks of equal volume is opened, air flows from the high pressure area to the low, and the second tank fills.

Since the second air tank is a tank of equal volume to the first, it will fill to 50 PSI, and the first tank pressure will drop to 50 PSI.

No loss in pressure, but equalization over the larger volume of tank.

In order to determine what the final pressure will be in the second tank at your facility, you will need to know it's volume, and compare it to the volume of the first tank.

In order to stop air pressure from the second tank from flowing back to the first tank, should air be depleted from the first, then you would install a non-return or check valve in the line between the two, stopping air pressure / flow backflow.

Cheers,

Bill
