air chuck from engine air compressor

[Gregory OConnor]

CFM cubic feet per minute is the rating that show the speed a
compressor will inflate. On the bus several of the many limiting
factors that restrict the high psi that is avaliable from the Detroit
compressor is the ;friction of a small id line ;small id protection
valve and small quick chuck fitting sets. the valve on the tire is
the final limiting factor but little high volumn air makes it to
there. when the tire pressure gets higher the small 110v compressors
may slow down a bit but they still pack close of the same volumn of
air into the tire. that volumn is what increase the psi.

if you put a connection point to the large hose off the compressor
and maintain a large id from there on, tire fill will be quick. but
that will require a large id protestion valve$$ and hose etc. the
best trick is to get a valve chuck with a clip that holds its self to
the tire valve. there are two types one that require the removal of
the schrader valve guts and onr that pushes the valve tounge in.
about $15. Napa.

Tire shops often remove the shrader valve guts from the tire to limit
the restriction and speed the inflate.

I had a coil of hose plugged into a quick chuck on my dump truck when
I got pulled over for a surprise (trap) inspection and received a
$240. fine and fix it ticket. the California CHP teach maintenance
respect with their ticket book. Pisses me off at the same time makes
me feel secure that all operators are reviewed with this scrutinity.
These guys would have a field day with a motorhome/bus.
