The Smoke machine is an eletro-mechanical unit which produces clouds of smoke on demand. Smoke machines are used in theatres, nightclubs, film and television studios, theme parks and other entertainment applications to produce a smoke or fog effect which creates the illusion of fog, steam, smoke from a fire, and many other effects. They are also used to create 'safe smoke' in fire training scenarios, for leak testing of buildings and containers, testing efficiency of extraction systems and air flow in wind tunnels. Their size can range from that of a small water bottle to arena-filling proportions. All our smoke machines generate a perfectly safe, white, non-toxic fog. UK mainland delivery as standard. Worldwide shipping available on most items.
