| The sky s the limit! Well not quite but you don t have to be restricted by the number of drying trays your dehydrator included. These add-a-trays allow you to expand upward and no tray rotation is necessary. How is that possible you ask? The drying pressure adjusts automatically to the number of trays you are using. Various models are expandable to different numbers of trays please check your owners guide.Extra tray to expand dehydrator capacity Fits American Harvest dehydrators FD-30 FD-40 FD-50 and FD-60 |
