Fermentation lock Silent Days and Nights

An exceptional airlock that due to its innovative design, ensures silent fermentation. Its inner piston is designed for calmer release of carbon dioxide molecules during fermentation. The piston runs very calmly and does not hit the walls of the airlock's body.

This airlock, adequately named Silent Days and Nights, has other advantages as well: it's stable, durable, easy to clean and remarkably practical. Its specially shaped stem allows it to be used
with seals of varying diameters: from 8.5 to 10 mm. Due to the application of an innovative, efficient venting system, the inside of the airlock is well protected against all sorts of pollution and
secure from flies and other insects. This allows to lower the probability of contaminating the brew during fermentation.
