To reduce turbulence, bothersome noise, and uncomfortable drafts in hood-intensive labs, consider delivering air through a 100% perforated ceiling plenum. To solve the rusting, flaking or decomposition of your chemical fume hood monkey bars (latticework), consider purchasing monkey bars made of carbon fiber. They are expensive, but provide a neat, clean, and resilient solution.
