An airlock is a system of two doors that are electronically interlocked so that both cannot be open at the same time. This can prevent contamination and prevent particles from outside the cleanroom from entering the cleanroom when personnel enter or exit the cleanroom.

What is the purpose of an airlock?

The airlock helps you keep an anaerobic atmosphere when fermenting. It prevents air from entering your fermentation vessel while still allowing the CO2 made during fermentation to escape. If your system didn’t have anywhere for this gas to go, the pressure would build up.

What is airlock in hospital?

An airlock is a transitional space that typically has two doors in series to separate a controlled environment (such as cleanroom, lab, operating room, or isolation room) from a corridor, or vice versa.
