Antari FLG-5 is a 5-litre water-based fog fluid formulated for standard fog and smoke machines. It is non-toxic, odourless, non-flammable, and independently laboratory tested with a published Safety Data Sheet confirming compliance with environmental and safety regulations.
It works in Antari fog machines and most other professional-grade foggers, produces thick, long-hang fog without oily residue, and is the default fluid used in professional event and hire environments internationally where audience safety and machine longevity both matter.

Why Does Fog Fluid Choice Actually Matter?
A fog machine is only as good as the fluid in it. The fluid determines three things that affect every show: fog density and hang time, machine health over time, and safety for the people in the room.
Generic or unbranded fog fluids vary significantly in formulation quality. Inconsistent glycol concentration produces inconsistent fog output — density varies between bottles, hang time is unpredictable, and the machine heater element works harder to vaporise poorly formulated fluid, accelerating wear on the heating block. Residue from lower-quality fluids also accumulates in the machine's fluid pathway, requiring more frequent cleaning and shortening service intervals.
Antari FLG-5 is formulated specifically for consistent vaporisation across the full temperature range of a professional fog machine heater. The water-based formula leaves no oily residue on stages, floors, or equipment. The output is reproducible and the same fluid in the same machine produces the same fog, show after show.
What Does "Heavy Fog" Mean and When Do You Need It?
Antari's FLG range is their heavy fog formulation, identified by the green label. Heavy fog is designed to produce dense, slow-dissipating atmospheric fog that fills a space and stays in the air - it's the kind of fog used for atmospheric haze, dramatic scene-setting, and beam enhancement in stage lighting.
This is distinct from low fog (ground-hugging dry ice effect, used for different machines) and light fog (faster dissipating, used for haze and beam work). FLG-5 is the general-purpose standard for shows, events, clubs, theatre productions, and any application where you want the fog to be visible and present in the space for an extended period after each burst from the machine.
For beam lighting effects where a moving head or PAR beam needs to be visible as a shaft of light through the air FLG-5 used at low continuous output is the standard approach. For dramatic atmospheric fill at the start of a scene or set, a higher output burst from the same fluid works.
Is Antari FLG-5 Safe for Audiences and Performers?
This is the question that matters most for anyone specifying fog fluid for venues with audiences. The short answer is yes, with context.
Antari FLG-5 is water-based, non-toxic, odourless, and non-irritating. The Safety Data Sheet (independently verified by laboratory testing) confirms the formula meets environmental and safety regulations. It is the fluid specified for use in venues including theatres, concert halls, clubs, schools, and corporate events where audience safety is a primary consideration.
The low-allergen profile is a practical advantage in mixed audience environments. Standard glycol-water fog fluids occasionally cause short-term throat or eye irritation in sensitive individuals at high concentrations. FLG-5's formulation is specifically developed to minimise this. At normal operating concentrations appropriate machine output for the room size it presents minimal risk for performers and audiences including children.
Practical notes for safe use: adequate ventilation in the venue reduces fluid concentration in the air. Fog machines should be sized appropriately for the room an overpowered machine used at full output in a small room with no ventilation will accumulate fog concentration beyond what any fluid's safety profile is designed for.
Machine Compatibility: Will FLG-5 Work in My Fog Machine?
FLG-5 is the native fluid for all Antari fog machines including the Z-series (Z800 and Z1200 MkIII and others) and is compatible with most other professional-grade foggers. The water-based formula is matched to the standard heating element temperature range common across professional fog machines.
Using the manufacturer's recommended fluid matters for warranty and machine longevity. Antari machines used with FLG-5 maintain consistent heater element condition and fluid pathway cleanliness. Using off-brand fluids with inconsistent glycol ratios or contaminants degrades heating elements and blocks fluid nozzles both common causes of fog machine failure that are avoidable.
For machines from other manufacturers: check the manufacturer's recommended glycol concentration. FLG-5's formulation is compatible with the standard specification used across most professional foggers. If you are uncertain, Edwards can advise based on your specific machine.
How Does FLG-5 Compare to Other Antari Fluids?
Antari produces several fluid formulations for different fog effects. The key distinctions:
| Fluid | Effect type | Use case |
|---|---|---|
| FLG-5 (this product) | Heavy fog, long hang | Atmospheric fill, beam enhancement, stage effects |
| FLL-5 | Low fog, ground-hugging | Dry ice effect alternative, theatrical ground fog |
| FLR-5 | Light fog | Fast-dissipating haze, beam work |
FLG-5 is the standard starting point for most applications. If you need ground fog or fast-clearing haze, the FLL-5 or FLR-5 are the right fluids — but they require specific machines designed for those effects. FLG-5 works in any standard fog machine.
Frequently Asked Questions
Can I mix FLG-5 with fluid from another brand already in my machine?
This is not recommended. Mixing fluids with different glycol concentrations or base formulations can affect vaporisation consistency and leave residue in the fluid pathway. If changing fluid type, run the machine until the existing fluid is exhausted or flush the system before switching.
How much fluid does a typical show use?
Consumption depends heavily on machine output, venue size, and how frequently you trigger the machine. A 700W–800W machine like the Antari Z800 MkIII running at moderate output for a 3–4 hour event typically uses 0.5–1 litre of fluid. A 5-litre bottle covers multiple events for most standard setups. High-output machines at full continuous use will consume more.
Does FLG-5 trigger smoke detectors?
Yes, it can. Smoke detectors — particularly ionisation-type detectors respond to particulate matter in the air, which includes fog fluid vapour at sufficient concentration. Optical/photoelectric detectors are generally more tolerant. For venues with active detection systems, fog should be used in conjunction with the venue's fire system management plan. Some venues temporarily disable or isolate detectors in the performance area during shows — this is a venue operations decision, not a fluid specification issue.
Is the safety data sheet available?
Yes. Antari publishes a full Safety Data Sheet (MSDS) for FLG-5, independently laboratory verified. It is available directly from the Edwards product page. The SDS confirms the formula's compliance with environmental and safety regulations and is the document to present to venue managers, health and safety officers, or production managers who require it.
