A CLEARER EQUIPMENT CHOICE

Evaporative cooler or air conditioner?

2026 season

An air cooler is not an air conditioner.

An evaporative cooler uses water evaporation, a misting fan disperses fine mist, and a compressor air conditioner uses a refrigeration cycle. Portable units can look similar while working differently and needing different conditions.

What do you mean by “portable air conditioning”?

Maintaining a set temperature in an enclosed room is different from refreshing guests in a garden or marquee. We clarify the goal and ventilation before recommending equipment.

The Provent range presented here includes misting fans and evaporative coolers. We do not describe them as compressor-based portable air conditioners.

Humidity and fresh airflow affect the result.

Evaporative cooling adds moisture to air as water evaporates. Its performance depends on starting humidity and temperature, with fresh airflow required. A fully enclosed room should not be assessed like an open terrace.

Air temperature at the unit outlet is not the temperature of the entire venue. Without measurements at your event, we do not promise a 10–15 °C reduction or any other fixed result.

How do we choose together?

Send photos or a sketch, your guest count and details of ventilation openings. Tell us whether the event runs during the hottest hours, how long it lasts and where people gather.

We assess whether the available equipment suits those conditions and suggest a layout. If evaporative cooling is unsuitable, that should be clarified before booking.

Frequently asked questions

Can an evaporative cooler cool a closed room like an air conditioner?

Not in the same way. It uses water evaporation and needs fresh airflow, unlike compressor air conditioning. You should not expect the same result or temperature control.

Will adding more units guarantee a particular temperature?

No. Equipment count is only one factor. Humidity, sun, openness and airflow all affect the result, especially outdoors.

Which of these devices does Provent rent?

We rent Mavejo misting fans and Master CCX 4.0 and BC 80 evaporative coolers. Delivery, setup and collection are agreed with your quote.
