![]() Particle size of fog is relatively large compared to other molecules in the air which is why the effect appears more like a fog or smoke. The thickness of fog is due to its particle size. You may also find in the specifications for a haze machine, that it will refer to an air pressure figure which is an indication of the power or output of the machine. However, to fill a large space, the hazer would have to be turned on early to create the desired effect. The major advantage over a fog machine is the fact there is no warm up time meaning haze can be instantly produced at any time. This is not only detrimental to the machine, but can be downright dangerous leaving slippery wet residue on grounds or in the worst case the machine ejecting boiling hot liquid with the risk of coming into contact with people causing severe burns.Ī compressor based haze machine uses oil based or water based haze fluid which is broken up into small particles using a compressor which then exit the machine usually through a filter to keep the particles small. Using fluid optimised to a different machine can result in incomplete vaporisation and result in wet fog where unvapourised fluid remains. Specific fluid formulas require a specific temperature range to optimise the vapourised output the machine produces. Different fog machines are made to different specifications, and as such, the fluid each manufacturer makes is tailored to the machines they produce. There is a very good reason for this, and it isn't just to keep on selling you their consumables after the purchase of their machine. Think, foggy morning when you can’t see further than what's in front of your hand.Įvery manufacturer tells you to only use their fluid in their branded machines, and never to mix or use fluids from other manufacturers or brands. Fog machines create a heavier denser fog compared to a light haze. ![]() The main advantage of fog machines is the ability to produce short sharp bursts, or long bursts of fog that can quickly fill a space. Machines built for the professional market tend to overcome the issue of reheating by managing the heating and flow of fluid to produce either a constant flow of fog or fog on demand at all times. Some machines may require time to warm up again after use which can be a problem in professional applications. Having a heating element means machines generally have a heating time of around 5 minutes or more before they can be used. Simply, fog and faze machines run on fog fluid and use a heating element to turn the fluid into fog. So, what's the difference between a fog, faze and haze machine? The density of the mist that a faze machine produces is less than that of a fog machine but more dense than the haze output from a compressor-based haze machine. The machine employs the same principle of a fog machine, using a heater element to heat up for fluid and vapourise it, but also uses a fan or fans to allow the fog to be dispersed more like haze. It describes a machine that uses glycol based fog fluid to produce a similar effect to a compressor based haze machine. The term Faze machine was originally coined by Antari, a company who has been manufacturing quality special effect products since 1984. Unfortunately, this has led to confusion and some very expensive mistakes due to users putting the wrong fluids into the machine. Of late, there have been a proliferation of machines called haze machines but actually run on glycol based fog fluid to produce a similar effect to traditional compressor-based haze machines. Fog machines seem more common as they are relatively inexpensive. ![]() Today, more commonly we hear the terms Hazer and Fogger machines. ![]() The term "smoke machine" has been phased out to eliminate people's concern of the term "smoke". Traditionally, liquid based atmospheric effects were limited to fog or smoke machines which ran on glycol based fluid to produce a foggy to smokey atmosphere. So what is the difference between them all? We all know fog and haze are crucial atmospheric effects used in a wide range of entertainment lighting shows to enhance the effects of lighting.
