What fluid does a fog machine need?

A fog machine needs a water-based fog fluid made from distilled water mixed with high-purity propylene glycol or glycerin. The distilled water prevents mineral residue, while the glycol or glycerin produces the visible fog when heated. Always use only the fluid recommended by the fog machine manufacturer, because machine and fluid form one matched unit — the wrong fluid can clog the heating element or reduce output. Different fluids deliver different results: quick-dissipating fluids clear fast, long-lasting fluids keep haze hanging for laser work, and scented fluids add fragrance for parties.

Which mini fog machine is best for small venues?

For small venues such as a party basement, a home setup or a small club corner, a mini fog machine with 400 to 700 watts of heating power and an output volume of around 60 m³/min is ideal. A compact mini fog machine fills small rooms quickly without over-fogging, stays portable and is easy to control via a cable or wireless remote. Look for a model with a timer function so the fog triggers automatically, and choose a unit with a magnetic valve for clean cut-off. At LTT you find compact mini fog machines from brands like Eurolite, Antari and Showtec.

Which fog machine is suitable for weddings?

For weddings, a low-fog (ground-fog) machine is the most popular choice, because it creates a magical, low-hanging fog that rolls across the floor — perfect for the first dance. Modern chiller-based or CO2-cooled low-fog machines achieve this dreamy ground fog without dry ice and run quietly and continuously. If you only want light atmosphere for the venue, a quiet hazer is a good alternative, as it adds a subtle haze that makes uplighting and beams glow without obscuring guests. Choose a unit with a timer or DMX control so the effect stays subtle and well-timed throughout the celebration.

What fog machines do fire brigades use for training?

Fire brigades use high-output fog machines specifically designed for training to create dense, realistic smoke that simulates reduced visibility during exercises. These training fog machines, often around 1600 watts and sometimes battery-powered for mobile use, produce thick fog quickly and frequently include an integrated timer and a rugged, durable housing for tough conditions. The artificial fog imitates the visual obstruction of a real fire without the heat or toxic combustion gases, allowing crews to practise search and rescue safely. The same fog is also used to test optical smoke detectors and fire-alarm systems.

What is the difference between a fog machine, hazer and fazer?

A fog machine (fogger) produces dense, opaque fog ideal for dramatic reveals and big effects. A hazer creates a fine, almost transparent haze that hangs evenly in the air and is the go-to choice for making light and laser beams visible without flooding the stage. A fazer sits between the two: it works like a fog machine but uses a built-in fan to swirl and distribute a light, even haze throughout the room. In short, choose a fogger for impact, a hazer for clean beam visibility, and a fazer for an even atmospheric layer across a space.

How many watts should a fog machine have?

The wattage you need depends on the venue. Around 400 to 1000 watts is plenty for home use, party basements and small private events. For clubs, discos, live events and open-air shows, choose 1500 watts or more, since higher heating power means more continuous fog and a larger output volume. Professional touring units reach 2600 to 3100 watts — for example the Smoke Factory Data II at 2600 watts or the Spock at 3100 watts — for spectacular, high-volume effects in big halls and outdoor productions. As a rule, match the wattage to the room size and the density you want.

Can fog machines trigger smoke detectors?

Yes, the fog from a fog machine can trigger optical smoke detectors, because the fine fluid droplets scatter light in the same way as real smoke particles. This is precisely why fire brigades and facility managers also use artificial fog to test the function of smoke detectors, fire-alarm systems and some automatic sprinkler systems. Before any event, coordinate with the venue, switch off or bridge the affected optical detectors where it is permitted, and reactivate them immediately after the show. Good ventilation and approved, low-residue fluids further reduce unintended alarms.

How do I control a fog machine via DMX?

To control a fog machine via DMX, connect its DMX input to your lighting console with a standard DMX-512 cable and assign the machine a DMX address. You can then program precise fog levels and timing directly into your show cues, synchronising fog with your lighting across the whole rig. DMX is the preferred professional control option because it integrates the fog machine into your existing console alongside every other fixture, and many modern units add RDM for remote status feedback. For overhead use, mount the machine on a truss with suitable hanging clamps and choose a model with a magnetic valve for clean fog cut-off.
