Product Information

The Symphony Diet 3D 12i Evaporative Air Cooler is a compact yet powerful cooling solution designed for modern homes and personal spaces up to 12m². With a 12-litre water tank, this tower-style air cooler offers extended operation without frequent refilling, while the powerful air blower ensures consistent airflow across the room. Its slim vertical build makes it ideal for tight spaces, and the integrated castor wheels allow effortless mobility between rooms. Engineered from durable engineering-grade plastic, the cooler maintains a robust form while staying lightweight at just 7.3kg.

Designed for optimal performance in moderately hot or humid climates, the Diet 3D 12i uses high-efficiency honeycomb cooling pads on three sides, paired with a cool flow dispenser for uniform air distribution. The inclusion of i-Pure Technology elevates your air quality with a multi-stage filtration system that helps remove dust, allergens, bacteria, and odours from the air. Whether you’re working, sleeping, or relaxing, you’ll enjoy cool, clean, and breathable air that enhances comfort and supports well-being.

This model is built for convenience, with a pop-up touchscreen control panel, auto-swing louvres, and a magnetic full-function remote. You can easily toggle between three fan speeds (low, medium, high) and set oscillation preferences for personalized cooling. It also features an empty tank alarm, so you’ll never have to worry about running dry unexpectedly. Despite its feature-rich design, the cooler is energy-efficient, consuming only 145 watts, and is compatible with inverter power sources for operation during power outages.

From its quiet blower-based cooling system to its thoughtful features like the refill reminder and ergonomic build, the Symphony Diet 3D 12i stands out as a stylish and intelligent air cooling option. Whether used as an air cooler, humidifier, or air purifier, it offers an eco-friendly and cost-effective alternative to traditional AC systems—ideal for bedrooms, studies, or small lounges where clean, efficient cooling is a must.
