For future reference -[ HMM ]-

Lubrication information tag hanging from the speed-control pull-chain of a mid-to-late 1950s-vintage Fresh'nd-Aire air circulator (the Successor to the Fan, as the tag boasts), about 2½" (63.5mm) tall. (I haven't yet posted a picture of the unit by itself, but it can be seen here; it has long since been relocated since I took that shot.)

 

I'll confess...even though this fan (sorry, air circulator) sees regular summertime use, I hadn't lubricated it in about fifteen years. Back when I first put it in service, I lubricated it with synthetic automatic transmission fluid instead of the oil recommended on the tag. Over the years, I noticed no performance loss. Since I had the unit apart on my workbench to clean off the accumulated dust inside and out before the photoshoot, I gave the bearings fresh squirts of ATF to keep the air circulator going for many years to come..

 

By the way, I couldn't help but search the address on the tag to see what became of the factory. It is now the site of an apartment building.
