I need to ask a stupid question. I have a portable air tank that I
have not used for 5 or so years, and I have forgotten how to use it.
Chalk it up to old age.
Anyway - it has no labelling on it whatsoever, so I have no idea who
made the thing. It resembles this one:
I can load it with what its gauge says is 100PSI, but I can get
nothing out of it. Obviously I am forgetting what to turn or
otherwise operate to make it release its air. I have a hose connected
(with a quick disconnect) and a trigger-controlled nozzle. I have two
nozzles, and have tried both. I have tried the hose with no nozzle. I
have backed off a little on a 1" knob, thinking that would release the
I told you it was dumb. I can't find my old manual nor can I find
same on the web.
Whar have I forgotten?

There isn't much to them. Just a hose/pipe connected to a tank with a valve and pressure gauge. One thing, is he sure he's really filling it? If you had
a gauge before a closed valve, it would read whatever pressure it's connected
up to, but no air would go in the tank. If it's really filling, he should see the pressure slowly climb. And if air goes in, it can't be clogged.
Also don't know what me means by tried it with the hose, but no nozzle.
The typical air disconnects, if there is no attachement, the hose connector
stays shut, no air will come out.

I'll try to be more speific. The tank has a gauge on it which read
80PSI before I successfullly added air to a 120PSI. I accomplished
that through a air fitting in the valve assembly on the top of the
tank which allowed the air to be added after I rotated a small knob a
bit. When I then closed that knob i could not add any more air. That
Now then, I have a 20' air hose to take air from the tank. I added a
'blow gun' to the hose similar to that at:
to a coupler similar to :
I get no air out of the gun, nor out of the coupler when I remove the
gun. The latter I expected.
The valve assembly on the top of the tank has a second knob under the
gauge on the outlet hose side of the assembly, which I expect controls
air going out. I have rotated that knob counter clockwise, first a
little bit, then a lot, to see if air would then come out. It does
Is the hose clogged? I thknk not. I have a second large compressor,
and tried the hose on it. Works fine.
Obviously I have missed something trivial here.
You are so right. There are two knobs, one associated wth the input,
one with the output. Not only do they both have to be open, but for
some reason they must be open to a specific point, no more, no less.
Anyway it works now/ I still feel stupid.
Thanks for help
In that link to a similar air tank sold by Home Depot that the OP
posted, there's the statement:
"Item cannot be shipped to the following state(s): AK,GU,HI,PR,VI"
...which I presume means Alaska, Guam, Hawaii, Puerto Rico and the US
I can't think of any safety related reason why they couldn't ship an
empty steel tank to any of these places.
Would it simply be that Home Depot only has a license with the
manufacturer to sell these tanks within the 48 contiguous states, and so
shipping them outside of that geographic territory would encroach on
some other retailer's license to sell that product?
No, I kinda doubt that would be it since the shipping costs are normally
borne by the customer. That might be the case if they offered FREE
shipping, but in that case they could just say "free shipping to the
contiguous 48 states". Then, someone in Alaska would have to reimburse
Home Depot for the higher shipping cost by simply paying more for the
item (with the shipping costs included in the bill).

Say the shipping more than doubles the cost of the tank and HD knows that
local stores, etc have the product at reasonable prices, so shipping them is ridiculous. So maybe they wanted to save customers the
time of screwing around, figuring out the shipping cost and then never
buying it anyway.
If that is true, your valve assembly is different from the one shown in
the Home Depot photo.
I have a tank that is nearly identical to the one from Home Depot. The
red wheel is one of three valves. It is the valve for the attached
hose. On mine, it is open when turned fully counter-clockwise, and shut
when turned fully clockwise.
A second valve is only for pressure relief in case you were to
over-pressurize the tank. In the Home Depot photo, it has a small ring
attached. You pull that ring to manually open the spring-loaded valve.
The third is a Schrader valve in the center of the red wheel, just like
the ones in your auto tires. On mine you can manually add air to the
tank via that valve whether the red wheel is open or closed. Pressing
on the pin in its center will let the air escape.
