Variable speed cooler. Once a year or so this fan requires 2 drops of oil. It works very well when properly maintained. I saw some in near perfect shape go for $250ish on line. A piece of veneer missing on one side, some dented vents. 18.5” tall, 19.5” at handle top. 21.25” wide. 13.5” deep. This example is a local celebrity. One can tell it was loved, & held a potted plant for some long time. Very powerful & quiet compared to a plastic housed fan. It does the job. 120 obo.
