Air Volume / Quality requirements for Yamaha YS100 and YVL88 Machines?

I checked the spec sheet and it gives pressure and no volume. The volume on one of my older Yamaha's was about 2.7 CFM. That corresponds roughly to the volume of a small 2HP compressor at your local hardware store. You can place on of these in a small chest with correctly oriented louvres which then stops the sound leaking out but allows air to freely circulate. The other solution is a quiet but considerably more expensive rotary compressor. Try an auction, but they do tend to be popular. Now as to air quality. Dry air is the spec. This means that the air doesn't cause condensation inside your machine when it is run in your atmospheric conditions. A galvanised pipe run along the side of your factory, with a few degrees of slope running into an water trap will do the job, with a pipe leading up and then to your machine, to stop any water getting into your machine. Or a refrigerated condensor at greater expense.
