Description

This portable evaporative air cooler provides energy-efficient cooling through natural water evaporation, using an ultra-low 100W rated power consumption that is significantly lower than compressor-based air conditioners and even lower than many comparable evaporative coolers, making it suitable for users seeking the lowest possible operating cost in dry and warm climates. The unit features a 25 L water tank that supports extended operation between refills, with a visible water-level indicator window on the front of the tank allowing users to monitor remaining water at a glance without opening the unit. The evaporative cooling method draws warm air through moistened cooling pads, where water evaporation absorbs heat and lowers the outgoing air temperature, while also adding beneficial humidity to dry environments.

The top-mounted mechanical control panel uses one rotary knob and two push buttons for straightforward, reliable operation without the complexity of digital controls. The extra-large front air outlet is fitted with three columns of adjustable louvers that allow users to direct the airflow horizontally and vertically to target specific areas or distribute cooling evenly across a room. The side-mounted intake grille draws in ambient air for the evaporative process, and the all-white upper body with a light gray tank base gives the unit a clean, neutral appearance suitable for both residential and light commercial environments. Four caster wheels make the unit easy to move between rooms, and the lightweight 6 kg net weight supports easy handling during setup and repositioning.

With product dimensions of 475 × 345 × 790 mm and a package size of 480 × 350 × 820 mm, the unit balances a substantial cooling footprint and extra-large outlet with manageable portability, and the net weight of 6 kg (7 kg gross) is notably lighter than many comparable evaporative coolers, supporting easy movement and installation. The 25 L tank capacity means the unit can run for extended periods without frequent refilling, which is particularly useful in spaces where continuous cooling is needed throughout the day. The ultra-low 100W power consumption also means the unit can be used in settings where electrical capacity is limited or where running a compressor-based air conditioner would be prohibitively expensive, and it supports running multiple units simultaneously without overloading standard household circuits.

The evaporative air cooler is suitable for a wide range of applications including homes, living rooms, bedrooms, home offices, small offices, retail shops, workshops, garages, outdoor patios, and dry-climate spaces where evaporative cooling is effective. With ultra-low 100W energy consumption, 25 L water tank, 220V/50Hz operation, mechanical knob control, extra-large adjustable front louvers, visible water-level indicator, four caster wheels, lightweight 6 kg design, and compact dimensions, this evaporative air cooler delivers efficient, low-cost cooling for small to medium indoor and semi-outdoor spaces with minimal energy expenditure.

Specifications

Applications

Primary Scenarios

• Residential Living Rooms & Bedrooms: Low-cost cooling for living rooms and bedrooms in dry and warm climates. The ultra-low 100W power consumption keeps electricity costs minimal compared to compressor AC, the 25L tank supports all-day operation, and the extra-large adjustable louvers direct cooling to seating or sleeping areas. The mechanical controls are simple for all household members to operate.
• Home Offices & Study Rooms: Energy-efficient cooling for home offices and study areas. The 100W draw means the unit can run for extended work sessions with negligible energy cost, and the caster wheels allow easy positioning near a desk. The mechanical operation produces no digital display glare in work environments.
• Small Retail Shops & Boutiques: Cost-effective cooling for small retail spaces and boutiques. The 25L tank reduces refill frequency during business hours, the extra-large louvers direct cooling to customer areas, and the clean all-white design fits naturally in retail environments.

Extended Scenarios

• Workshops & Garages: Portable cooling for workshops, garages, and hobby spaces where compressor AC may be impractical or too expensive to run. The caster wheels allow positioning near workbenches, and the ultra-low 100W draw works with standard household circuits even when power tools are also in use.
• Outdoor Patios & Semi-Outdoor Spaces: Evaporative cooling for outdoor patios, covered decks, and semi-outdoor spaces where evaporative coolers are most effective due to natural ventilation. The 25L tank supports extended outdoor use, and the caster wheels allow easy movement in and out of storage.
• Small Offices & Break Rooms: Bulk cooling for small offices, reception areas, and staff break rooms. The ultra-low energy consumption supports running multiple units without high electricity costs, and the mechanical controls are intuitive for all staff to use.
• Warehouses & Storage Areas: Spot cooling for small warehouses and storage areas where full HVAC is impractical. The 25L tank reduces maintenance frequency, and the caster wheels allow the unit to be moved to where workers are positioned.
• Cafes & Small Food Service: Customer-area cooling for small cafes, coffee shops, and food service counters. The extra-large louvers direct cooling to customer seating, and the low noise of mechanical operation (no compressor) supports a comfortable dining environment.
• Classrooms & Training Rooms: Cooling for small classrooms and training rooms in dry climates. The 25L tank supports full-day operation, the caster wheels allow movement between rooms, and the simple mechanical controls are easy for facility staff to manage.
• Greenhouses & Plant Nurseries: Humidity and cooling management for small greenhouses and plant nurseries. Evaporative coolers both lower temperature and add humidity, which can benefit certain plants, and the 25L tank supports continuous operation.
• Gyms & Fitness Studios: Cooling for small gyms and fitness studios. The high airflow (typical of evaporative coolers with extra-large outlets) supports rapid air movement during exercise, and the ultra-low energy consumption supports extended operating hours.
• RVs & Mobile Homes: Portable cooling for RVs and mobile homes where electrical capacity may be limited. The 100W draw is highly compatible with standard RV electrical systems, and the lightweight 6 kg design supports easy positioning in tight mobile living spaces.
• Dormitories & Shared Housing: Affordable cooling for dorm rooms and shared housing where installing compressor AC may be restricted or expensive. The ultra-low power consumption and mechanical controls make it suitable for shared environments.
• Dry-Climate Regions: Specifically effective in dry, hot regions (such as desert climates, high-altitude areas, and regions with low summer humidity) where evaporative cooling delivers maximum temperature drop. In humid climates, evaporative cooling effectiveness is reduced.
