Description

This portable evaporative air cooler provides energy-efficient cooling through natural water evaporation, using a 135W rated power consumption that is significantly lower than compressor-based air conditioners, making it suitable for users seeking low-cost cooling in dry and warm climates. The unit features a large 30 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 three rotary knobs for straightforward, reliable operation without the complexity of digital controls. The large front air outlet is fitted with 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 two-tone body design — light gray upper section with a dark gray tank base — gives the unit a clean, functional appearance suitable for both residential and light commercial environments. Side carry handles and four caster wheels with brakes make the unit easy to move between rooms and secure in position once placed.

With product dimensions of 370 × 330 × 760 mm and a package size of 475 × 370 × 800 mm, the unit balances a substantial cooling footprint with manageable portability, and the net weight of 9.5 kg (10 kg gross) supports easy handling during setup and movement. The 30 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 low 135W 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.

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 135W low energy consumption, 30 L large water tank, 220V/50Hz operation, mechanical knob control, adjustable front louvers, visible water-level indicator, four caster wheels with brakes, side carry handles, and compact dimensions, this evaporative air cooler delivers efficient, low-cost cooling for small to medium indoor and semi-outdoor spaces.

Specifications

Applications

Primary Scenarios

• Residential Living Rooms & Bedrooms: Low-cost cooling for living rooms and bedrooms in dry and warm climates. The 135W power consumption keeps electricity costs low compared to compressor AC, the 30L tank supports all-day operation, and the 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 low power consumption means the unit can run for extended work sessions without high energy costs, 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 30L tank reduces refill frequency during business hours, the adjustable louvers direct cooling to customer areas, and the clean two-tone 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 with brakes allow positioning near workbenches, and the side carry handles aid movement between work areas. The low 135W draw works with standard household circuits.
• 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 30L 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 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 30L 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 adjustable 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 30L 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 30L tank supports continuous operation.
• Gyms & Fitness Studios: Cooling for small gyms and fitness studios. The high airflow (typical of evaporative coolers) supports rapid air movement during exercise, and the low energy consumption supports extended operating hours.
• RVs & Mobile Homes: Portable cooling for RVs and mobile homes where electrical capacity may be limited. The 135W draw is compatible with standard RV electrical systems, and the compact dimensions (370×330×760mm) fit 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 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.
