Printing Presses and Air Leaks

[lostmind]

This may be a stupid question...I'm not a pressman, but are invisible (silent) air leaks a common problem with printing presses? Tried different compressor situations but the psi (125) falls to about 90 when opened to the press. We've had leaks before but you can normally hear them if they're bad enough.

Not a common problem but a definite possibility.
Everything is pneumatic these days and while not preferable, sometimes the best (only) way to counter very minor leaks is to have a compressor that can simply keep up, or out-pace them.

Thanks. Kind of what I figured.

That’s not meant to be a permanent solution and there are ways of locating any kind of air leak if it becomes too much of a problem. You don’t want to have a compressor always working harder than it would normally have to.

When you say the pressure drops from 125 to 90 psi as soon as you open it to the press, does it stay at 90 psi, or does it keep dropping?

It stays at 90 psi. We were able to hear small air leaks today from under the walkway from what are believed to be for the blanket washers? (This is a Komori Lithrone 28).
