Inquiry (采购产品): technical info We have a Dustkop dust collector. How far can I run a dust collecting tube to a machine, and what diameter should the tube be? The machine is a CNC with four walls around the work area and the top is partially open (I plan to close in the top.) The distance between the dust collector and the machine is approx. 50-60 feet and there are several other openings in the line to collect dust at other machines. **** Hidden Message ***** John Packard 180 Pleasant St Rockland, MA 02370-1229 USA Company: Polymer Corporation Title: Mfg.
