The subject line pretty much says it.
I am just looking for suggestions, comments, or confirmations.
I've a 1/2" galvanized line running across the west end of the shop.
At south end I've a regulator/filter that takes the 150 to 175 psi
air from the 80 gallon tank (on the north end) down to 90 psi or less.
I am also looking at running 1/2" galvanized down the north wall of the
shop with a regulator/filter near the east end by the big door.
There are two outlets at the regulators. One is a quick disconnect to
the regulated air and the other to the *unregulated* high pressure
air. It doesn't bother me working with these pressures, but the
thought of some one else coming in that isn't familiar with the
things that can go wrong makes me a bit uncomfortable. I have seen what
a 20' hose that lost the end can do at this pressure let alone a 100'.
(I have seen about 10 guys in a shop go under the benches until some one
was able to get to the main shut off. I didn't think a couple of the
guys that over weight could move that fast)<g>
It's NOISY too.
At any rate I am trying to figure the safest way to have the ability to
hook the air hoses to either supply safely. For some things the
regulated just cannot supply enough air as in sand blasting.
The high pressure disconnect will be the farthest from each door and I
could make it a bit more difficult to reach if necessary, but when
something goes wrong that is usually the one you want to grab.
BTW the manifold shut off is reachable by going through either door so
a hose on the loose will not prevent any one from getting to the shut
off. If worse comes to worse the circuit breaker for the compressor is
on the opposite corner of the shop from the compressor. OTOH a hose
loose with and 80 gallon high pressure supply can do a *lot* of
damage.

Slightly OT: Shop high pressure air manifold.
