Paranoid, please help!

PostWed Oct 13, 2021 6:49 am

Ok so I know that this was very stupid.

I got the Bmpcc4k last week and finally got to set it up yesterday. While doing so, I went to remove the side Plugs, as I’m using a Rig setup and they are kind of in the way. All this is fine, but I got paranoid that some dirt might have gotten in there.

I had my Air duster in reach and decided to spray some in there. I wasn’t thinking and a little bit of liquid sprayed out. I sprayed it from a safe distance, however now im extremely worried that it might have broken something.

The camera seems to be working just fine and I know Air duster (especially the kind for electronics) should be safe even when liquid is sprayed, as it evaporates in less than a second. It also couldnt have hit the camera sensor. Only the cable slots and meaby slightly the motherboard.

Am I going to be fine?

All you need to know about canned air:
https://www.techspray.com/everything-yo ... aid-to-ask

Due to the aerosol duster valving design, they generally can only be sprayed right-side-up or, at most, a 45º angle. Under high pressure, the propellant is mostly liquid, with the empty part of the can filled with vapor. When you spray an aerosol duster, the vapors of the propellant are expelled. As you rotate the can, the liquid starts to spray out and at a very low temperature (as low as -60ºF / -51.5ºC). Techspray® offers Vortex 360, which is specifically designed to spray only gas as you rotate the can. As a side note, this also explains why it is a bad idea to shake up a can of duster before use, as is the habit of using spray paint. If you shake the duster, the liquid propellant is more likely to sputter out as you start spraying.
Saying "Thx for help!" is not a crime.

I never use canned air on camera equipment, only a bulb-style rocket blower.
