Running External Airline Automatically Mazak

Hello,

I have a Mazak Nexus 250 Quick Turn machine that currently has an air line that is always running to blow off excess material. I am looking to automate the on/off action of the air line such that it is only on when the machine is running. I would like to hook the air line through the machine somehow, maybe by hijacking the coolant function as we run no coolant on this particular machine. I was planning on putting a solenoid on the air line, maybe it could be controlled by M8/M9? Does anybody have any ideas on how to accomplish this?

Thanks in advance!
