Overview


Engineered for rugged outdoor use, the 4 in 1 Large Capacity 20L Outdoor Air Cooler is a heavy-duty cooling solution designed to tackle extreme heat. This versatile unit combines four functions: air cooler, fan, humidifier, and air purifier, making it a multi-purpose tool for outdoor adventures and industrial settings. The massive 20-liter water tank offers up to 24 hours of continuous operation, while the high-power motor generates a wind speed of 4.5m/s, effectively cooling large areas up to 30m².


Built with a durable, weather-resistant ABS shell and reinforced base, it withstands outdoor elements like dust, light rain, and temperature fluctuations. The unit features a telescopic handle and heavy-duty wheels for easy transport across uneven terrain, ideal for construction sites, campsites, or large outdoor events. The advanced cooling system includes four-sided cooling pads and a powerful misting nozzle, delivering rapid temperature reduction even in scorching environments.


Features


1. 4-in-1 Functionality: Switch between cooling, fanning, humidifying, and purifying modes to adapt to different environmental needs.

2. Massive 20L Tank: The largest capacity in the series, providing all-day cooling without frequent refilling—perfect for remote locations.

3. High Wind Power: The 3-speed motor (low/medium/high) delivers strong airflow, making it effective in open-air spaces like patios, warehouses, or sports fields.

4. Outdoor-Ready Design: Waterproof control panel, UV-resistant casing, and durable wheels ensure reliability in harsh conditions.

5. Air Purification Filter: A built-in activated carbon filter removes dust, pollen, and odors, improving air quality wherever it's used.


Application


This heavy-duty cooler is designed for outdoor and industrial environments, including construction sites, camping trips, outdoor concerts, agricultural settings, and large workshops. The 20L tank and high wind power make it ideal for areas with limited water access or where rapid cooling of large spaces is required. The four functions offer versatility: use it as a fan for ventilation, a humidifier to add moisture in dry barns, or a cooler to create a comfortable zone at a campsite. Its mobility features allow users to position it exactly where cooling is needed, even in remote or rugged locations.


FAQ


Q: Can this cooler be used in rainy conditions?

A: While the casing is weather-resistant, avoid exposing it to heavy rain. The control panel is waterproof, but prolonged exposure may damage internal components.

Q: How long does the water last on the highest fan speed?

A: On high speed with misting, the 20L tank lasts approximately 12 hours; on low speed without misting, it can run for 24 hours.

Q: Is the air purifier filter replaceable?

A: Yes, the filter should be replaced every 6 months or sooner if used in dusty environments. Replacement filters are available for purchase.

Q: What is the noise level on high speed?

A: It operates at 65dB on high speed, which is comparable to a household vacuum cleaner—suitable for outdoor use but less ideal for quiet indoor spaces.
