Looking for an Exposure unit

Hey All,

I am looking for an exposure unit that can hold a screen that is as bit as 25 by 36. The faster the burn time the better. I would also like a vacum system to come along with the unit. Please let me know what you recommend.

Look for a used AmerGraph 150 or NuArc 3140. They're not cheap, but they're good. You might run across a used setup that is set up with a MH light source and a separate vacuum-frame, or maybe a used offset plate exposure unit that can be modified. Most blacklight tube units don't come large enough to fit the frame size you're looking at. You can make your own. I built one that had 10 48" unfiltered blacklights, a vacuum frame made with pond liner from Home Depot, and a GraLab darkroom timer to set exposure times and shut off the lights. Cost me a couple hundred to make.
