Interesting.
I'll bet it's to prevent people from getting too close to the sensor with the nozzle and getting frost on or freezing the sensor.
If used from 6 to 8", NEVER shake the can, and keep it upright while spraying, it should be okay...
I'll do it.
Love to know what the propellant is in them.
Butane? Never use near ignition sources?

Some have a "bitterant" in them so that humans don't use them to get high.

People.....
I wonder if the bitterant is a gas also.

I’ll keep using a bulb blower. Safe as long as I don’t touch any tender parts. I’ve even seen models with a filter to catch moisture. That’s too persnickety for me.

I have a bulb blower also...
At least no one mentioned using a clean booth,
yet...

The can of compressed gas may not contain any water but can cool the surface to the extent it may cause liquid condensation on the surface if held too close. The escaping gas may be below the dew point of the surrounding ambient air therefore pull the humidity out of the air as water. Also the contents of the can may be a liquefied form of a gas under pressure. If held too close to the surface some of the liquefied gas may be deposited on the surface before it has a chance to boil off as a gas, thereby causing condensation on the surface.

Ahh. A man of physics.
And to be safe, the manufacturer says "Don't use it on....".

A computer tech who installed a new HD for me told me not to use canned air on a PC. If it’s bad for a PC, it’s bad for a camera.
On a PC??? I don't use canned air. I use air from a 300HP compressor at 100PSI.

Any way if the thing is moving around you should be able to remove it quite easily as it doesn't stick that well. I don't know if the Z50 has the vibrating cleaning feature. I think that is good enough for that.

I'll bet that REALLY cleans the cooling fan!

(Does it have an air drier???
)Yes it does clean well. And yes we have several air driers too but the air isn't absolutely dry though. Actually the 300HP is the largest. We run a 200HP, a 250HP and a 300HP all the time. Sometimes we need an additional 150HP.
But that isn't a lot. A company I worked for back in the 90 we had a 1500HP, 4 800HP and a few 400HP air compressors.

I'll guess a sensor dust particle.
The fact that it's moving indicates it's not stuck on the sensor and it might be able to be blown off with canned air.
Is it there in live view?

I would not use canned air. First it is under high pressure, and second it contains a liquid propellant. If it gets on the sensor it could damage it. Instead, I would recommend a hand blower like the Giotto rocket blower. If that's not enough to remove the dust particle, next step is to clean the sensor.

Curious, where was that explained?
I use canned air for variety of purposes. If you do not hold the can straight up the liquid propellant will come out along with the air. It is a risky proposition to use it on a sensor and I would avoid it.

Well, for example, if the material in the can is liquid CO2 (nitrogen, etc.), then the vapor (air) in the can is plain CO2 gas, I don't think liquid CO2 contains moisture... The can does not contain <ambient> "air" that was compressed.
I wonder how/where he got his information....
Maybe he read it on the internet.
I'll continue to use canned air without any fear of "moisture".

Well I can say, is that you've been lucky. Try holding the can sideways or upside down If you want to see liquid come out with the air. It is just a risky proposition to use canned compressed air on sensitive camera gear. As a number of people have pointed out in this thread, it is definitely not recommended.
