Rosco Mini-V — compact fog for airflow & HVAC testing
The most compact machine in the range delivers a powerful, continuous stream of professional-quality fog — and is small enough to fit right inside standard ductwork. No training, press-and-hold simple, and ideal for industrial airflow, HVAC and leak-detection work.

What it is
Professional fog in a compact, go-anywhere unit
A durable, energy-efficient heat exchanger heats quickly and delivers a solid, continuous stream of fog from a simple on/off rocker — no training needed for technicians, students or engineers. Light enough to carry anywhere, and sized to fit comfortably into standard duct work, which makes it an excellent choice for industrial applications such as HVAC testing.
- Compact & light — 5.4 kg, 400 mm long
- Fits inside standard ductwork
- Powerful continuous fog from a simple on/off remote
- No training required to operate
- Durable, energy-efficient heat exchanger
- Runs the full Rosco fog-fluid range
- Rugged 12-gauge steel case
Where it fits
The industrial & airflow specialist
Where a full-size generator won't fit or isn't needed, the Mini-V shines: HVAC and duct-leak testing, construction draft and gas-path detection, point-source airflow visualisation in labs and rigs, and mobile technical work. Introduce fog into a duct or cavity and every leak and airflow path shows itself.

Which fluid for the Mini-V?
It runs the full Rosco fog-fluid range. For visible airflow and leak-tracing, the standard fog fluid gives dense, long-hanging smoke; for a lighter, faster-clearing trace, Stage & Studio.
