I've used a Le-Maitre G-300 hooked up to a home made CO2
unit. Due to it being in a black box, we had to place the Fogger about 25 feet away and outside of the
theatre due to noise. The show was in an
Arena setting and the
effect happened at the load doors into the space. We had the CO2
unit right after the fogger that
fed into dryer hose that eventually ran to the
PVC pipe with holes. I used sewer drain pipe that has the holes already drilled into it and then a simple cap at the end of it. In that 25 feet, the
fog did not warm up enough to just float out, it came shooting down in a perfect wall of
fog. I've also done it with blocks of dry ice with results that weren't as good but still nice.
I can't imagine doing it with the new Ultratec G-3000. I haven't played with that one yet but their new outputs are amazing. I bought two of their
Stage Fogger
DMX units which I was told was supposedly the replacement for the G150 and I think it puts out the same volume that the G300 did. I'd love to see the output in person on the new G-3000.
