Misting, fogging or dry fog? Compare before you choose.
A practical side-by-side guide to low and high-pressure misting, fogging, dry fog and fog cannons – pressure, droplet size, wetting and best uses.
Misting vs fogging vs dry fog vs fog cannon
| Low-pressure misting | High-pressure misting | Fogging | Dry fog (air atomising) | Fog cannon | |
|---|---|---|---|---|---|
| Typical pressure | Up to ~10 bar | ~70 bar (35–100) | 70–140 bar | Water + compressed air | Pump + high-volume fan |
| Droplet size | 50–80 µm | ~10–20 µm | Finer than misting | 1–10 µm range | Varies with nozzle ring |
| Main job | Watering, budget cooling | Cooling, dust, odour | Humidity, cooling, effects | Fine dust where material must stay dry | Large open areas, long throw |
| Wetting | Likely | Low if designed well | Low with treated water | Very low | Depends on throw and wind |
| Water treatment | Basic filter | 5 micron filter, softening if hard | Treated / RO water advised | Filtered water + clean air | Filtered water |
| Best for | Gardens, nurseries | Factories, restaurants, sheds | Greenhouses, textile, mushroom | Conveyors, hoppers, transfer points | Yards, demolition, haul roads |
Values are typical ranges used for early selection. Final pressure, droplet size and nozzle count are set by engineering review for each site.
Four questions that settle most choices
Is the air humid?
Evaporation slows in humid air. Finer droplets and airflow matter more – or misting may not suit.
Can anything get wet?
Paper, cement, food or electronics need dry fog or careful high-pressure design.
Is there airflow?
Fans or natural breeze carry mist and carry away humid air. Closed rooms need ventilation.
What is your water?
Hard borewell water blocks nozzles; filtration or softening is part of the system.
Read the detail
High-pressure misting
Pump-driven 70 bar class systems for fine, fast-evaporating droplets.
Fogging systems
70–140 bar fog for humidification, cooling and visual effects.
Dry fog dust suppression
Micron-sized fog for fine dust where material must stay dry.
Fog cannons
Long-throw mist cannons for open yards, demolition and haul roads.
Misting fan systems
Fan-mounted mist rings that push cooled air across large spaces.
Evaporative cooling
Water-based cooling for spaces where air conditioning is impractical.
Questions we are often asked
Is fogging better than misting?
Not always. Fogging is better for humidification and greenhouses because the fog hangs and evaporates; misting with fans is usually better for cooling people in semi-open spaces. The application decides.
What is dry fog?
Dry fog uses air-atomising nozzles that mix compressed air and water to make droplets of only a few microns. They capture fine dust without wetting the material – useful at conveyor transfer points and hoppers.
When is a fog cannon the right choice?
When the area is too large or open for fixed nozzle lines – stockyards, demolition sites, haul roads and loading areas. A cannon throws mist up to about 50 metres, depending on the model.
