Pacific Energy Spectrum 27 Centrifugal Fan Blower

[DOC Robbins]

Greetings all,

In your opinion, which direction (Forward or Backward) would I use to gain the most efficient airflow over the heavy plate-steel top? Its time to clean the fins so would like to see what the comments are. Currently, I have a backward fan set up. Many thanks.

Backward seems right to me. Although, I believe forward may be less prone to dust accumulation.
