Hitachi airHome 400 DJ50PHAE - inverter air conditioner - split system

The Hitachi airHome 400 RAK-DJ50PHAE/RAC-DJ50PHAE air conditioner is a modern inverter split system that is ideal for a home or office. It not only cools or heats a room up to 50 m², but also creates a comfortable atmosphere thanks to thoughtful functions and stylish design. I myself was recently choosing an air conditioner for my apartment, and this model caught my attention with its energy efficiency and technology. Let's figure out what makes it special.

What's so cool about this air conditioner?

FrostWash self-cleaning

This feature is a real godsend. The air conditioner freezes the heat exchanger to -15°C to collect dust and dirt, then defrosts and washes it away. This keeps the air clean and the unit works more efficiently. I read that such systems preserve air quality three times better than models without FrostWash.

Mold Guard

After turning off, the air conditioner automatically blows out the internal parts to prevent mold or unpleasant odors. Plus, it heats the components up to 50°C to kill bacteria. This is important to me because humid air is often a problem in the summer.

Control from your smartphone

Thanks to Wi-Fi, you can adjust the temperature or operating schedule via the airCloud Home app. For example, turn on the cooling when you're halfway home. And there's also support for voice control - convenient when your hands are busy.

Eco Sensor for savings

The presence sensor is like a little helper. If there is no one in the room, the air conditioner raises or lowers the temperature slightly to save energy. After 20 minutes of no movement – +1°C, after another 20 – another +1°C. You come back – and everything immediately returns to your settings.

SafeGuard reliability

The outdoor unit is protected from corrosion, voltage surges and even extreme weather. There is a 3-minute start-up delay to prevent damage to the compressor. This is very important for our climate.

Five fan speeds

You can choose the air supply strength. For the bedroom, we recommend choosing the minimum - quiet and comfortable.

Why choose Hitachi airHome 400?

• Savings: Class A++ and R32 freon reduce electricity costs.

• Silence: 20 dB is like the rustling of leaves, perfect for sleeping.

• Clean air: Filters and FrostWash take care of health, which is especially important for families with children.

• Convenience: Wi-Fi and a backlit remote make control easy.

• Reliability: Japanese quality is not just words, the equipment really lasts for years.

What does it look like and how is it installed?

The indoor unit is compact, with a minimalist design - fits into any interior. The outdoor unit is resistant to rain, snow and rust. Installation is standard: indoor and outdoor units, a main line up to 3 m, a drainage pipe. I advise you to hire proven craftsmen so that everything works like clockwork.
