In this case the nozzle penetrates the neck of the bottle by 75 mm; this depth prevents any swirling in the neck, making the blowing more efficient. The injection of sterile water is followed by a series of blasts of air which has also been sterilized by mircrofiltration. The presence of the bottle sets up the machine for the opening of the injector, but the actual injection of the water or air is controlled by external cams, which can easily be modified to increase or reduce injection times. The water and air circuits are completely separate.
Forced draining alternated with draining by gravity allows for better drainage of the water, minimizing the residue in the bottle and the consumption of air. The two steps can also be used differently, for example by injecting first air and then nitrogen. The height can be adjusted manually or electrically.
