In a few days my Doosan DNM 5700 will finally show up to the new shop. I need to be ready to hook it up to air and power so the install guys can do their thing. This will be the only machine in the shop for a while, and I'm not running 24/7 production.
The machine pre-install document says it needs 9cfm at 80 psi. I don't think the shop has any 240v outlets, but there are plenty of 120v outlets. I'm tempted to get a Harbor Freight compressor like this:
21 gal. 2-1/2 HP 125 PSI Cast Iron Vertical Air Compressor
or this
6 Gallon Air Compressor - 2 Stage, 5 HP, 165 PSI
and a dryer like this
Compressed Air Dryer - Save on this Compressed Air Dryer
I don't know if the smaller compressor is good enough with capacity. I hope the DNM 5700 doesn't consume 5 cubic feet of air per minute just for the spindle air purge.......my thought is that as long as the compressor has a tank full of air well over 80psi, then the intermittent draw from the machine for tool changes wouldn't be a problem. Am I wrong? I don't plan on using the machines air blast through the spindle continuously.
The larger compressor would handle it, but it's a lot more expensive and I would have to get an electrician to put in a 240v outlet.
What do you guys recommend?
