Now that bigblockyeti mentions it, I also have the Powermatic 180 and it is not hooked to DC at all. Mainly because at this stage in it's life it is considered a toy. I use it at night whenever I am tinkering or playing with it. I plane boards with it with absolutely no DC connected at all and don't have any issues. But there are some design differences with my PM180 than my Woodmaster. We have 2 woodmasters and neither one will feed well without DC. I don't run either Woodmaster without the hood though so maybe that is the key difference.
Actually just a month ago, upon moving into our new shop and without DC, we had to run both woodmasters without DC until I could get duct work ran and it was just terrible. On my smaller Woodmaster we run moldings, I would be pushing on the infeed and my partner would be pulling on the outfeed just to get a stick ran through with no DC. Then just yesterday, since having DC hooked up, I ran about 20 sticks of molding effortlessly watching as my feed rollers pulled the sticks through nicely.
But I do know my PM 180 has no issues running without DC, but the cover/hood on my PM180 is much smaller and less cumbersome to remove and re install than what is on the Woodmaster.
I would question what type of wood will you be planing. Like in my experience, I have planed Mesquite and that stuff will just come apart at any time. Hickory being such a hard wood will also chip out from time to time throwing chunks of wood.
I personally would go the route of a cheap DC that was positioned right next to the planer. Or maybe even a cheap leaf blower. I use a cheap leaf blower in my shop to blow off the dust and do some shop clean up.
