It really depends on the type of pump the OP has got. For example The Mitsubishi EP series don't have an air tank, they have an accumulator (Mitsubishi's term for a small presure tank with a diaphragm)
The WP series does have an air tank.

Any professional plumber's supplies should have one, up to 500 or 1,000 l. Can't be much more specific unless you're in my area.

Any particular reason why you need one rather than a storage tank and a constant pressure pump, which have them built in (large, with the big 'drum' ones, or small with the smaller square ones)?

Yes there is an issue I don't like, when a water faucet is opened to run slow the water is constantly surging up and down, no steady flow.

Right and wrong, not a fraud-----correct, yes I am thoroughly convinced of my Christian beliefs but not a dogmatist, at least not according to the definition.

Actual pressure tanks of 40-75 gallons or so with a bladder are available. I purchased mine in Mukdahan, actually made in USA. I have my own well and test the water about annually and it is drinkable, no microbacteria , etc. The advantage of a closed system like this is the water remains clean as it's not open to the atmosphere, and water pressure is fairly constant. My 75 is connected to a 20 GPM submersible well pump. I know of at least 2 shops here selling these, some from US, others from a Thai supplier. I have also found them in Udon, and awhile back I saw some stainless type at Global, but didn't seem that well made. The larger tank capacity allows a longer on and off run time.

So, what's been going on, Khun Peters, update please.
