This is because airlock rooms generally do not need ample surplus supply air to keep up the needed stress differential necessary to circumvent reverse circulation resulting from air turbulence during doorway operation. Whether or not a room is supplied which has a quickly-response (1 to 3 seconds) VAV air provide system to offer excess surplus air, It's not necessarily speedy adequate to circumvent an airborne cross contamination.

As gasses Make up inside the fermenter, bubbles will stand up through the drinking water, with the s-shape, then outside of the highest on the airlock.
Having said that, an absence of bubbles would not routinely mean that fermentation has stopped or is comprehensive, and the presence of bubbles might not indicate that fermentation is occurring.
Any manufacturing amenities the place the merchandise calls for protection from particulate although the people outside the cleanroom don't need defense from your product from the cleanrooms.
