I was a little bit hasty in suggesting a 60 psi spare tyre might be a

I tried it earlier to realise the valve is just designed for slow filling,
and has a very restricted airflow when deflating.

Point is, it doesn't take an awful lot of air to blow dust off a heatsink.
I usually brush off what I can before resorting to using my lungs and
blowing off the remaining inaccessible stuff.
Trouble is this always ends up with some in my lungs and nasal passages.

I dunno - VW for years drove their window washing system from the spare tire
(anyone else remember those days?). It was always a memory contest to make
sure to refill the tire, or be stranded by the side of the road as the air
lines often leaked. Tires were not-so-good in those days as well.

If all you need is that one lungful, consider a small portable tankless
compressor ($15 at your nearest auto-supply) and a refillable aerosol can.
No more than 100psi in most cases, but it would do what you lungs can do.
For that matter, you could fill such a can from the tire, a double-schraeder
fill fitting is cheap enough to fabricate.

Betcha if you do this, you _will_ wish for more...

Yes, no doubt I will.

I took 4 Power Amplifiers round to the nearby garage today to blow out using
their airline - we are more friends than business accomplices, and they will
happily let me do that for free.
But I have to load the amps in my car and drive it round there.

And yes, it's great to have a huge tank and massive pressure if you have the
space to keep it in.
Worked a treat, so it did.


I discussed this subject with them, and they pretty much said the same
thing - No, you need big pressure, you need big tank, small tank empties
quickly.
(They are Russian)
Also, big tank with high pressure, if explodes, you damage your building.
Big problem, very dangerous.

My workshop is actually now in a Music Shop. A big tank exploding in there
is not even worth thinking about.
A noisy compressor is not ideal either, and I don't have the space to store
it anyway, being as Retail Space in a city centre is rather expensive.
