A low-lying fog machine, also referred to as a fog chiller, ground fog generator, low fog machine, or low fogger, is specially designed to produce fog that stays close to the ground. These machines create a dense, ground-hugging fog that doesn’t rise into the air. They are commonly used in a wide range of applications, including concerts, weddings, theater productions, discos, operas, dance performances, magic shows, circuses, theme parks, television and film sets, sports events, special effects, as well as military and fire training exercises.
