S-Bubble Type Airlock

The advantage of the S-bubble type airlock is that it has a smaller chamber so you can more closely observe the CO2 rising and therefore the rate of fermentation. It is also handy when you’re cooling a beer as there is less chance of sucking airlock water back into the fermentation. The down side is that they cannot be cleaned manually if they get dirty during the ferment. That is why we do not prefer them for the active portion of the primary fermentation when the krausen (foam) might get forced up into the airlock.
