Rosco Fog & Haze Machines — Professional, Specified, Controllable (AU & NZ)
Rosco fog & haze machines · Australia & New Zealand
Fog machines built as instruments, not party effects.
Rosco fog and haze machines are specified, controllable and repeatable — the tools engineers, universities, mines, safety trainers and professional theatres reach for when the smoke has to behave the same way every time. This is not entertainment or import gear. Here's the difference, and how to choose the right machine and fluid.
Not an entertainment fog machine
Why professionals don't use a DJ or import machine
For a show it might not matter. For airflow measurement, safety training, ventilation studies or a broadcast cue, it matters completely — the smoke has to be controllable, consistent, clean and certified. That's the line between a Rosco and an aftermarket unit.
Rosco
Controllable, repeatable output
Dial the exact density you need. From a fine wisp to a billowing cloud, output is set by temperature and pump control — and it repeats.
Rosco
Consistent, even flow
Same smoke, shot after shot. Engineered pumps and nozzles hold a steady particle size and flow — essential when you're measuring, not just filling a room.
Rosco
Known, clean fluid
Water-based, GRAS, no oily residue. Rosco fluids are low-molecular-weight glycols in de-ionised water, on the USFDA GRAS list, with no oily film left on people or equipment.
Rosco
Specified & approved
Certified for real work. CE, ETL/cETL, RoHS, Actor's Equity listed and AMPTP Safety Bulletin #10 compliant — documentation that stands up to a safety officer.
Rosco
Serviceable & reliable
Built to keep running. Rugged 12-gauge steel case, one-step cleaning and common core parts designed to be swapped quickly — years of service, not disposable.
Rosco
Engineered machine + fluid
Tuned to work together. Each machine is matched to its fluid — the V-Hazer's temperature, pressure and nozzle are engineered specifically to aerosolise V-Hazer fluid.
Who uses them & why
Specified for serious work
We focus on the applications where fog is a tool, not a gimmick — where consistency, control and clean, known smoke actually change the outcome.
Aerodynamics & airflow visualization
Engineering and physics departments use fog to make airflow visible — around models in wind tunnels, over aerofoils, through ducts and rigs. The result is only as good as the smoke: it has to be even, repeatable and a known particle size, or the data is noise.
Why Rosco: fine, controllable output and consistent, clean water-based smoke — the same flow, shot after shot. Used by engineers, technicians and students who need a specified instrument, not a party effect.
Ventilation & escape-route airflow
Fog traces where air actually goes — ventilation paths through tunnels and workings, and how smoke would travel in an emergency so escape routes and refuge strategies can be checked against reality.
Why Rosco: high, controllable, repeatable output and a clean, known fluid — you can run the same test again and trust the result. Rugged 12-gauge steel machines built to keep working.
Leak, draft & gas-path detection
Introduce fog into ductwork, cavities or a sealed space and every leak, draft, gap and pressure path shows itself — the fastest way to find where air (and gas) is escaping or migrating, and to prove a seal.
Why Rosco: the compact Mini-V fits right inside standard ductwork; precise output lets you dose exactly what a space needs. Finding leaks improves airflow efficiency and cuts energy cost.
Realistic smoke environments
Fire departments, military bases and airports create realistic smoke for search-and-rescue and preparedness training. The environment has to be repeatable and safe for people to work in, session after session.
Why Rosco: non-toxic, water-based fog on the USFDA GRAS list, controllable density, and continuous output — the Vapour indoors, the Vapour Plus for large or outdoor scenarios.
Fog & haze you can trust on a cue
When a cue has to hit the same way every night, in front of an audience, the machine and fluid have to be dependable, controllable from the desk, and clean around performers and rigging.
Why Rosco: integrated DMX, fine output control, near-silent haze (V-Hazer under 35 dB), Academy Award®-winning fluids and Actor's Equity listing. The industry standard, not an import.
Step 1 · Choose your machine
Four machines — start with your job
Pick by what you need the smoke to do and how big the space is. Vapour and V-Hazer are the two we specify most — the fog workhorse and the silent hazer. Every machine opens to a full detail & specs page.
Rosco Vapour
Continuous fog · 3.6 L/hr · fine control
The professional standard for continuous, precisely controllable fog. Solid DMX control, easy servicing, and the widest range of effects — from a fine wisp to a rolling cloud.
Rosco V-Hazer
Continuous haze · 0.9 L/hr · under 35 dB
Near-silent, water-based haze that leaves no oily or damaging residue — cleaner than oil- or glycerin-based hazers — from a compact 14.5 kg body. Independently tested for professional theatre and included under the Equity-League Equipment-Based Guidelines.
Rosco Vapour Plus
Continuous fog · 7.2 L/hr · twin-pump
Twin pumps and double the output for large venues, outdoor scenarios and high-volume work — stadium-scale fog and even cryo-style burst effects.
Rosco Mini-V
Continuous fog · 1 L/hr · fits ductwork
The compact, no-training unit that fits inside standard ductwork — ideal for HVAC and airflow testing, mobile rigs and anywhere a full-size generator won't fit.
