For those seeking cleaner air, a heat exchange ventilation system that requires no ductwork.
Japan Stiebel VLR-70 Series
A ductless heat exchange ventilation system that is easy to install. An allergy sweep filter that suppresses viruses and odors, keeping indoor air clean, is also available as an option.
The "VLR-70" is a heat exchange ventilation system that comes standard with an Allergysweep filter, which adsorbs and decomposes bacteria, allergens, odors, and more, achieving cleaner air quality. The maximum airflow is 70m³/h, and airflow can be set to five different levels. Features: ■ Allergysweep Filter The filter uses "Allergysweep," a main agent made from highly safe plant-derived components (such as extracts from ginkgo leaves and gallnuts). It also suppresses and deodorizes bacteria, viruses, allergens like dust mites and cedar pollen, and mold. Additionally, a wide variety of filter options are available to choose from based on your living environment and preferred air quality. ■ High-Performance Aluminum Heat Exchange Element With an industry-leading heat exchange efficiency of 92%. The heat exchange element is washable, keeping the device and home air consistently clean. ■ Color Variations The indoor side is available in three colors, while the outdoor side can be chosen from up to four colors, allowing you to match your interior and exterior wall colors or personal preferences. ■ Optional Items CO2 sensors and humidity sensors can also be installed, allowing you to control the necessary ventilation volume when needed. ■ Centralized Control System One controller can manage up to eight units of the main body. *Note: Optional items are available for the VLR-70E series.
