got this fan from a demolition site back in december last year this version of K56 is the best condition i've found so far! its canopies are also much less yellowed than other 70s SMCs that i've obtained very well built and blows a crazy amount of air! these are the true models of the K and KN series!     |

In all the SMC that you posted, this one seems the closest to the 1972 60F I got last November. Only the extension pole and the lower canopy seems different.
I always wonder why you never paint the canopies on your fans?

i usually paint the metallic ones and plastic ones to different colors (brown for example)
SMC canopies i usually dont paint them to keep up their logos, i dont want to risk painting and have their logos damaged..

What is the CFM rating on one of these?

You could still paint the upper canopy. Actually with masking tape and an x-acto it would be possible to hide the logo as it's in relief and the golden parts would not get painted. |

How much air it moves, usually measured in CFM (cubic feet of air per minute).. Maybe the measurements are different in other parts of the world..

I dont know how to calculate that, but it blows a lot of air

Oooh this looks so good. Some of your older SMCs really look their age lol, the condition of this one is superb.
An accurate, reported CFM isn't going to exist for a product this old, regardless. CFM only became relevant in the United States/North America in the last decade or two due to the energy usage regulations, before that it was either irrelevant, wildly inaccurate, or unreported.

I actually have at least two fans that predates the 1990's where the amount of air moved is written directly on the sticker or tag of the fan. It's calculated in CMM.
I would not know how to calculate it either.

Right, but that's part of my point. Values calculated that long ago are probably off compared to what they'd be if calculated by regulation today. There was no industry standard, so even while many manufacturers measured it in their own way, it was basically a useless value if compared to something tested by another manufacturer. It's only useful now because everyone's required to utilize the same system of measurement.

Oh no nothing like that. CMM is the same thing as CFM except that it uses meters. The way of calculating it is the same otherwise. Some countries have been asking fans companies to put this info on the box or the tag of their fans as early as the 1950's.
One way of doing it that is more different if those that calculates it by hour instead of by minutes.
