I have been checking specs for several floor fans, and some of them list two figures for the amount of air they move. This came from a manual for a 16" floor fan I found:

What is the difference between these figures?

I tried googling it and I only got a straight answer from Gemini which seems wrong. The actual results talk about other fan parameters, but not the fan flow rate.
Gemini says the fan flow rate would be unobstructed, while airflow would consider some static pressure. This seems wrong since the airflow figures are always higher than the fan flow rate ones.

("Weird Coffee Person" James Hoffman decided to roast coffee beans by deep-frying them.)

This industrial fan should be enough for my kids room.

This Weird ad popped up for an art show in the next town. Who would think of wearing an aeroplane?

It made me laugh and it has jet engine fans, so I thought I'd share. I don't think it breaks any rules here.

I thought I'd ask the the fan experts here, what is the best neck fan? I work at Amazon and it has been hotter than Hell and I work 10 hour shifts. I would prefer something that would help keep me cool and have a long battery life.

Thanks in advance!!

I didn’t realise there were specific fans?

We know what happened

This lovely specimen was tucked away in a Cape Cod cottage. Such a gentle breath and a faint whisper of motion.

Small but it does very good at blow jobs it keeps you cool even though it is handheld

No complaints

Beaten up, Shakes like its addicted to drugs but blows alright.
