A fog machine, fog generator, or smoke machine is a device that emits a dense vapor that appears similar to fog or smoke. This artificial fog is most commonly used in professional entertainment applications, but smaller, more affordable fog machines are becoming common for personal use. Fog machines can also be found in use in a variety of ...
Theatrical smoke and fog, also known as special effect smoke, fog or haze, is a category of atmospheric effects used in the entertainment industry.The use of fogs can be found throughout motion picture and television productions, live theatre, concerts, at nightclubs and raves, amusement and theme parks and even in video arcades and similar venues.
Pump spray haze machines use electricity or compressed CO 2 to power a spray pump connected to a mixing valve, which draws in and atomizes the fluid. Pump hazers also includes machines which function in the same manner as a fog machine, pumping fluid into a heated chamber where it is vapourized to produce a cloud. Hazers which heat fluid to ...
Ultra low volume fogging machines consists of a blower, a formulation-holding tank and in some equipment a pump. The machine can have an electric, battery or gasoline engine that drives the blower. The blower creates a low pressure area and forces air through the nozzle of the fog machine. Air pressure can be controlled by adjusting the engine ...
State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.
During 2001-2006, a total of 466 fogger-related illnesses or injuries were identified in the United States by the SENSOR-Pesticides program. These illnesses or injuries often resulted from inability or failure to vacate before the fogger discharged, reentry into the treated space too soon after the fogger was discharged, excessive use of foggers for the space being treated, and failure to ...
Security smoke is a thermally generated white fog, aimed at inhibiting intruders from accessing items to steal, much used in the storage of high-value goods, and recommended by police and insurers. It consists of glycol or glycerine mixed with distilled water , which vaporises and then condenses in the air.
The fog originates from the bulk water into which the dry ice is placed, and not from atmospheric water vapor (as is commonly assumed). [23] It is occasionally used to freeze and remove warts. [24] However, liquid nitrogen performs better in this role, as it is colder, thereby requiring less time to act, and needs less pressure to store. [25]
