Hi,
Well it depends on the manufacturer but most if not all give the =
delivery
rate. Usually X cfm at around 90 psi. But beware, not all take it that
serious and go for a generous figure especially in the hobby range.
The delivery rate is of prime importance as this indicates the capacity =
of
the compressor. On most tools you will find the amount it takes to drive =
the
tool. To be of the right size you need a compressor which can cope with
that. Normally the compressor is taken such a size as to deliver at =
least =BC
more air as needed. Ideal it would be =BD but in most case that=92s not
practical.
Anyway take it big enough so it is not compressing anything for at least =
25%
of the time. That gives the head time to cool down and makes it live =
longer.
Also if the choice between two equal go for the lower rev.
