Thanks to WiFi connectivity, you can turn on the air conditioner before arriving home, adapt operating schedules, or change the temperature without directly using the wireless remote control.

Flash Streamer technology to improve air quality

The Daikin Perfera FTXM50B incorporates Flash Streamer technology, an air treatment system developed by Daikin that uses high-speed electron discharge to help reduce certain allergens and odors present in the environment.

This technology is combined with different filtration elements:

• Silver particle filter: helps capture certain allergens present in the air, such as pollen.
• Titanium apatite deodorizing filter: helps reduce unpleasant odors.
• Air filter: helps retain dust particles circulating through the indoor unit.

These technologies help improve indoor air quality and provide a more comfortable environment during air conditioner operation.

To maintain system performance, it is important to carry out the filter cleaning and maintenance operations indicated by Daikin.

Two-zone intelligent motion sensor

The indoor unit includes a two-zone intelligent presence sensor that detects where people are located and adjusts air distribution to prevent the airflow from blowing directly on occupants.

When no presence is detected for a certain period, it can automatically activate an energy-saving setting to help reduce electricity consumption.

This function is especially useful in living rooms, offices, and spaces where people change position throughout the day.

Even air distribution with Comfort+ and 3D airflow

Daikin's Comfort+ system uses dual flaps to improve air distribution and promote a more even temperature in the room.

In cooling mode, the air can be directed toward the upper part of the room to reduce direct drafts. In heating mode, the airflow direction adapts to promote the circulation of warm air.

Meanwhile, 3D Airflow technology combines automatic vertical and horizontal swing to distribute air across different areas of the room, reaching areas far from the indoor unit.

These functions provide more uniform climate control and improve comfort in living rooms, dining rooms, and large spaces.

Quiet operation

The Daikin Perfera TXM50B air conditioner is designed to offer quiet operation, although the noise level depends on the fan speed and selected mode.

The FTXM50B indoor unit reaches a minimum sound pressure of 27 dB(A) in cooling and 31 dB(A) in heating, according to Daikin's official technical data sheet.

These values correspond to the indoor fan's quiet mode. At higher speeds, the unit provides greater airflow to condition spaces with higher thermal demands.
