Voice and app control from anywhere: Fully compatible with Amazon Alexa and Google Home, the Grandbreeze responds to voice commands and connects to the Klarstein app — so you can set the temperature before you've even left the office.
Uninterrupted sleep on hot nights: Night Mode automatically adjusts cooling output and runs at a maximum of 65 dB — quiet enough for bedrooms so you wake up rested, not groggy.
No installation, no hassle: The telescopic exhaust hose and window sealing kit are included, and lockable castors let you roll the Grandbreeze from room to room in seconds — no engineer, no drill, no delay.
Product description
Say goodbye to tropical nights and overheated offices – the Klarstein Grandbreeze reliably cools rooms up to 56 m² to a comfortable temperature, all without installation or a handyman appointment.
With 12,000 BTU and energy efficiency class A+, the Grandbreeze delivers powerful cooling performance with low power consumption: 1.1 kWh per hour, standby consumption only 0.5 W. The airflow of 390 m³/h distributes the cool air evenly throughout the room, and the desired temperature can be continuously adjusted between 18 and 32 °C. Three operating levels and an automatic vertical air swing ensure cooling reaches exactly where it is needed.
The device works as a 3-in-1 solution: air conditioner, fan, and dehumidifier in one unit – no additional device required. The integrated dust filter keeps the room air clean, and the 0.8-l water tank with level indicator operates independently until full capacity is reached. The dehumidification performance is 1.5 l/h. Night mode and 24-hour timer automatically adjust operation to your daily routine.
Via the Klarstein app, temperature, operating mode, and timer can be conveniently controlled from your smartphone – even remotely. Amazon Alexa and Google Home are fully integrated, allowing voice commands directly through smart speakers or mobile phones. Plan your cooling so that your home is pleasantly tempered upon arrival. The refrigerant R290 has a low greenhouse potential and is considered a particularly energy-saving choice in its device class.
The Grandbreeze is the right choice for apartments, offices, and hotel rooms between 42 and 56 m² – wherever a fixed air conditioning system is not an option. The telescopic exhaust hose and window sealing set are included, and the wheels with locks can be easily moved on any surface.
Get the Grandbreeze and enjoy comfortable temperatures – all summer long.
