Cylindrical Airlock DUPLEX 1A
High quality (A-brand) cylindrical airlock for barrels from 60 to 120 L. Cylindrical airlocks are easier to clean than classic twin-bubble models and don't dry up as fast.
- Dimensions (Ø x H): 8 cm x 20,5 cm
- Suitable for an opening of 17 mm
- Fill the airlock with a little water or disinfection solution so it acts as a siphon; the beer is closed of from the outside air by the water, hence preventing bacteria to enter. However the carbon dioxide formed during fermentation can escape.
The water in the airlock evaporates, so regularly checking and refilling is necessary!
