All about ANTARI Fog

I. Fog Machine

A fog machine (also called s smoke machine) is a device which emits a dense vapor that appears similar to fog or smoke. This artificial fog or smoke is presently widely used within the entertainment industry. Most fog machines create the fog by either vaporizing a water and glycol-based or glycerine-based fluid. For glycol-based fogs, the fluid (fog liquid) is injected into a heater element, and evaporates quickly. The resulting pressure forces the vapor out of fog machine nozzle. Upon coming into contact with cool outside air the evaporation forms a fog. Because of the reflective and refractive qualities of the smoke created by fog machines, they are now widely used in night clubs, stages, and concerts to enhance the effects of lighting and laser arrangements (laser beams.)

Nowadays, fog machines have different applications such as for industrial purposes, such as visualising the flow of air or testing filters in air conditioning, for fire fighters training program, and for occasions where simulation of smoke is required. (eg. Army training, fire drill testing for public transportations.

II. Fog Effect In General

Basing on Antari’s products, there are 3 types of fog in today's fog effects. Those 3 kinds are produced by Hazer, Fazer, and fog machine. Let’s see which the difference between Hazers, Fazers and Fog Machines are:

1. Hazer: Creates a very fine mist

No heater. It uses an air compressor to create a very fine mist that hangs in the air and allows the light beams to be seen in the air (laser beams). It uses a special hazer liquid. This is usually mineral oil based (not glycol). It is NOT the same as fog liquid. A hazer can't use fog liquid it must use hazer liquid. The differences between a fog and haze machine basically lie on the following points:

A. Liquid: Most of the fog machines use water based fluid as its source of effects. In opposite, most haze machines use oil-based fluid as its source of effects.

B. Working principle: Fog machines use “heat” to make fog. Haze machines use “pressure” to make haze.

Because of the above differences, each type has its own advantages and disadvantages as below:

A. Haze machine produce extremely fine particle that will hang in the air for a longer time than those produced by fog machines. In opposite, fog machines produce a burst of dense fog that may disappear in a short time. (Fog hanging time may vary based on different fluid formulas)

B. Due to its fluid nature (oil based), haze tend to accentuate the beauty of light beams, which is rather important for lighting professionals.

C. Haze machine has no warming up time as it doesn’t use heater element.

D. The total owner cost of fog machines is a lot cheaper than haze machines.

E. The Haze machine performs with a special translucent and long lasting effects that is specifically for big concerts, stage or film studio. The fog machine is used for pub, club, disco, concerts, home party and theater, etc.
