I have a question reguarding fan speed reduction late in the schedules. I read an article years ago that in most kiln schedules, fan speed could be reduced late in the schedule to reduce costs. I can't find the article, who wrote it or any of the specifics. We are running pondersa pine shop, commons and dimension and white fir dimension. Fan speed is 100% fan speed thru all the schedules and velocity is 700 ft/min. Can we reduce fan speed and when can this be accomplished in the schedules? Thanks.

We also reduce fan speed at the end of our schedules on all species. I am told it saves not only energy, but it can help lengthen the life of your fan motors!!!
