My shop is currently setup with a dust collection system using 6" spiral metal pipe running from my cyclone (located in an equipment room) with drops/blast gates at each machine. I'm wondering it I could/should utilize a section of the duct work for my laser exhaust. I would isolate the section of pipe from the cyclone with a blast gate (shown in red), and direct it to a dedicated blower to exhaust the laser fumes directly outside. I would also add a blast gate to isolate the laser exhaust blower, for when operating the cyclone. The attached diagram shows my current setup, with proposed additions in red.

My other option would be to run dedicated ducting for the laser, but just wondering if "sharing" some of the existing ducting is ok, which would same me some time and effort. unfortunately, running new duct work straight out next to the air compressor is not possible, due to obstructions.
