Giant 20' x 3' x 2' router build

Big Steel box with 2 fans pulling air in thru good paper filters and one pulling it out. Filters like this. http://www.apc.com/products/family/?id=414

Car air filters also make good filters but you'll need to make an housing similair to whats in the picture. Which is easy made from thin ali sheet if you have a working machine and a good little test.

Put it inside with it. If you need or want to see the display then depending on VFD make you can often remove the front display and put externally.

If your controling thru software then you don't really need access but it's nice to be able to see the display and have it set for Amps. This will give an indication to cutter wear and spindle load. (thou don't think your foam will challenge the spindle any.!!)

make sure the fans blow into the panel (via the filter), not suck out of it, this is to keep the air pressure inside the panel higher than outside.
