Howdy,

If I were buying a compressor today and the air requirements were modest, I
would be looking HARD at one of the super quiet compressor types that are
available now.

HF link just because it's easy, but there are also name brand versions of
this type of thing IIRC...

With all this going on, I have been doing some thinking about having to

to come with a 3hp, 4hp, and 5hp motor.=C2=A0 I have the 5hp.=C2=A0 I
