Rosco Vapour Fog Machine

The workhorse of Rosco's new family of fog machines, the Vapour comes packed with all of the features that a professional effects technician could want - including solid reliability and ease of maintenance. Combining high-volume, continuous fog output, with a simple, one-step cleaning process and common core components that are designed to be replaced quickly - the Vapour can be relied upon to get the job done.

Precise output control allows the Vapour the widest range of atmospheric effects and makes it versatile for use in virtually any venue. Careful monitoring of temperature and pump speed results in both fine wisps of smoke or billowing, continuous clouds of fog.


Fog and haze differ in that fog is a thick, opaque effect that lasts a short time, while haze is a thin, translucent effect that lasts a long time. Fog is used as a special effect, whereas haze is used for lighting/atmosphere enhancement.


Whether created by nature or machine, fog consists of liquid droplets suspended in the air. Fog machines create fog by vaporizing fog fluid – that is, they convert the fog fluid from a liquid form to an aerosol form. Most fog machines accomplish this by forcing the fluid at high pressure through a heated pipe.

Bursts of fog are typically used for special effects in live and filmed productions. They’re useful for anything from causing a cigar to “smoke” in a small ashtray, to obscuring a huge battlefield. Fog is a smoke-like effect; however, it’s not smoke, since smoke consists of solid particles rather than liquid droplets. (Also, smoke is usually created by burning, and although fog machines do heat the fog fluid to vaporize it, they don’t burn it.)

Fog can also be made to stay low to the ground, for a “walking on clouds” effect. This is usually accomplished by ducting the fog through a cold chamber to cool it. Typically, fog fluid for creating fast-dissipating fog is used, so that the fog will evaporate before it warms and begins to rise. Some machines make low fog by mixing a cryogenic liquid (such as liquid nitrogen) or solid (such as dry ice) with hot water.


Like fog, haze consists of liquid droplets, but the drops are very fine and are distributed evenly over a large area to form a mist. Some haze machines vaporize fluid by forcing it through a heater, and others vaporize it using high air pressure.

The primary use of haze is to make light beams visible. Since light reflects off the droplets, you will see light travelling through the air that you ordinarily would not see. Haze is also used to create a misty atmosphere.
