Cleaning work near domestic installations can create pressure peaks due to the vacuum in front of the nozzle and the overpressure behind it, which may lead to pressure equalization through sanitary connections. The Bulldog® Antiblast specifically reduces these pressure differences, thereby minimizing the risk of water escaping through connected sanitary installations. The Bulldog® Antiblast was developed and tested by enz® in collaboration with a renowned technical institute and meets high standards for functionality and cleaning performance.
