can i recover R134a system

this pump is not designed to "recover" anything. (there isn't any way to collect the exhaust.) It just pulls a vacuum on an "empty" system. You still need gauges and hoses to do even that.

Can this be used to suck all the air out of a closed pvc pipe?

I you can come up with the correct fittings to hook it up air tight, it will vacuum out anything.

does it come with oil

***no oil comes with it!!!*** you can order (1- quart) from amazon for: $5.27 + $5.49 shipping = $10.76 or buy it today from: o'reilly auto & autozone for around $9.00 or $10.00 my pump has worked great for (2+ years!) ***be sure to keep it oiled at all times.*** good luck...

What would I have to do to use this with my small cnc router outfit and vacuum hold down devices?

I'm not sure I understand the question. CNC router, cutter and this ? This vacuum is exclusively for vacuuming moisture from an AC system. That is what I use it for
