Metalic union in T shape to join different air vents responsible to make circulate the air of two growing tents and redirect them into a single output.
It is an ideal complement for those cases where isn't available more than one location and we want to connect the outputs of the extractors to the outside using just one output, and avoiding having to make two holes in the wall, window or wood for the extraction of stale air.
It can also be used for introduce forced air from the outside and so, we avoid having too many air passages distributed around the site of the crop.
