Duct Features

Slim & Compact design

In the case of bottom return air connection, not only does the indoor unit design allow for installation in a narrow ceiling space of up to 270 mm, Further space savings have been achieved by mounting the control box internally inside the chassis.

Two-direction drain piping

Easy maintenance

Structural improvement is attained by making the bottom panel two pieces, front and rear. The internal fan casing is also manufactured in two pieces, namely upper and lower. The maintenance of the motor and fan can be easily carried out by removing the rear panel and the lower part of the casing while leaving the main chassis installed.

Big Duct Features

Separation is possible by lightweight compact design

The indoor unit can be separated into fan unit and heat-exchanger unit to assist the installation works.

Automatic Airflow adjustment function

This function can set the optimum airflow automatically, so installation time is shortened drastically.

High Energy Efficiency

Energy efficiency is improved drastically by new airflow design.

Low Operation Sound

Drastic improvement in efficiency and low noise are realized by uniform air speed and airflow path to the heat exchanger.

  1. Air Stabilizer
  2. V-shape heat exchanger
  3. Efficient airflow design
  4. High efficient - DC fan motor Lower power consumption
