So I want to make an industrial computer one day. The biggest issue that I will need to cover is that it will need to be dust proof.

What makes an industrial computer an industrial computer?
Maybe the enclosure that they are in is made of thicker grade sheet steel?
Maybe they are air tight or dust tight?


So if I need to make a dust proof computer case/ controller enclosure. How will I keep it cool?

I can't just make it an airtight box, casue the heat from all the drivers and power supplies will cook everything. So I would need to add probably two holes to the case. One for air flow in and one for aitflow out.

But

Will just a simple foam type sponge be good enough as an air cleaner? These will be for use in welding and fabrication shops where lots and lots of grinding and plasma dust will be.

My last plasma machine, there was dust everywhere. All over the monitor, all into the computer vents.....everywhere.

The computer didn't short out or anything, but I still need to make an enclosure as robust and clean as possible for all the electronics.

Any ideas?

Cheers,
Peter
