Nathanael,
For our manual spin stations, we keep spinners mounted or embedded in a fume hood below deck level. Bowls are exhausted through plenum. Top side of the hood has FFU to help minimize particulate and the hood stays slightly negative pressure to the room. We will always have such workstations to remain flexible on the multitude of resists being processed, but are working on bringing up some coat tracks to address the most common resists.
Best,

We have all of our spin coaters under a canopy exhaust that captures a lot of the fumes, but you can still smell it. Do others put the coaters in a fume hood? Perhaps use respirators? Or is it not that big of a concern if you capture most of it?
