Air King 9236D Direct Drive Drum Fan

This is a direct drive drum fan, so it typically requires the least amount of maintenance of any barrel & drum style fan. This model spins at 1120 RPM, and produces 10,900 CFM, but these high revolutions usually create quite a bit of noise (78 decibels on high). A direct drive fan is great for airplane hangers and industrial manufacturing plants where noise levels won’t be a concern.
