Toshiba Heat-Air® Series Total Heat Exchange Units
Introducing the new large airflow type (1,500m³/h・2,000m³/h) for the Toshiba Heat-Air® Series!
Release Date: August 2025
Key Features
1. Achieves High External Static Pressure for Large Airflow Ventilation
High external static pressure capability ensures sufficient airflow even over long duct runs, enhancing design flexibility and installation ease. This also helps meet the increased ventilation requirements that have become common since the COVID-19 pandemic.
2. Equipped with High-Efficiency DC Motor
Constant airflow control simplifies ventilation calculations. The unit automatically adjusts ventilation to maintain a constant airflow, adjustable in 1% increments between 30% and 120% of the rated airflow. Constant power control allows for stepless adjustment of static pressure-airflow characteristics, enabling fine-tuning and energy savings. Settings can be adjusted in 1% increments within the 5% to 100% range of maximum power.
3. Supports CO₂/PM2.5 Sensors for Air Environment Monitoring
CO₂ and PM2.5 sensors (optional accessories) display air quality status on the remote control. Ventilation volume can be automatically controlled based on detected concentrations, even when using the constant airflow control mode.
4. Insect-Proof Filter (Optional Accessory) for Easy Maintenance
Insects adhere to the filter surface, preventing them from falling off. A single maintenance cover allows easy removal of both the pre-filter and the insect-proof filter, simplifying cleaning. The filter is washable. Note: The insect-proof filter and the high-performance filter cannot be used together.
5. Centrally Manageable Microcomputer Type
Enables integrated control with Toshiba's VRF air conditioning system "Super Multi u" series and central control systems.

Note: Power consumption, current, and exchange efficiency values are for the rated airflow. Temperature and enthalpy exchange efficiency values are based on the display standards specified in JIS B 8628:2017. Noise levels are measured 1.5m below the center of the unit. Temperature exchange efficiency indicates the average value during cooling and heating.
