How it works
Both machines turn a fluid into tiny droplets that float in the air. A hazer makes very fine droplets and spreads them evenly, so the air looks almost clear but every beam passing through it becomes visible. A fogger makes larger droplets in thick bursts, so you see the smoke itself.
For laser and lighting shows, haze is the usual choice: it shows the beams without hiding the performers. Fog is used for moments, such as a reveal or an entrance. Low fog is a third type, chilled so it stays on the floor.
Good to know
- A beam show needs haze. Without it, the audience sees almost nothing in the air.
- Venue smoke detectors may need to be isolated during the show, with the venue and fire officer agreeing the process.
- Air conditioning and outdoor wind clear haze fast, so outdoor shows need more output and careful placement.
- Water-based and oil-based fluids look and linger differently. Pick the fluid for the venue.
