An airgapped system in this context is one that is intentionally not connected to any network. In most cases, no networking hardware is present, so the only way to get data onto and off of the system is via physical access. Which makes attacks by anyone but an insider virtually impossible, and data exfiltration without regular physical contact to collect the data pretty damn hard. This is just a proof of concept for making that last part easier.

Pretty trivial actually. It takes careful shielding, and possibly jammers, to keep electromagnetic radiation from leaking secrets. Look up the U.S. Fed Gov TEMPEST standards for an example of real paranoia. Serious counterintelligence people also consider acoustic emissions from computing equipment.

Pretty much every antivirus firm uses airgapped systems to study (new) computer viruses and malware in order to create countermeasures and detection algorithms.
