The PU-AA50 air purifier equipped with a coaxial reversing propeller fan jointly developed by Japan Dec (Nidec) and Zojirushi Co., Ltd. won the Energy Conservation Center Chairman's Award in the Product and Business Model category of the 2021 Energy Conservation Awards, which was presented by the Energy Conservation Center of Japan.

Statistics from the Ministry of Health, Labor and Welfare of Japan show that the number of patients with allergic diseases has been increasing in recent years, and the demand for air purifiers that can effectively relieve allergy symptoms is expected to continue to grow. PU-AA50 is an air purifier suitable for large spaces (24 tatami mats, about 38.88 square meters) with excellent air cleaning ability and low noise performance, and it can absorb and clean the air from 360 degrees above the ground, which is prone to pollen and dust accumulation, and is also a living space for young children. PU-AA50 purifies indoor air with a large amount of air that can be blown to the ceiling. In addition, the product operates at only 39 decibels, which is quieter than in the library, and the power of 10 watts is about 20% of that of the competition in its class, so it won the award.

The feature of the coaxial reversing propeller fan is that by rotating the two types of fans that have been optimally designed in the opposite direction, the counter-rotating fan recovers the rotational component of the air generated by the first fan, resulting in a very straight wind that can reach a distance. Japan Electro has previously used the coaxial reverse propeller fan for server cooling fans, and Japan Electro has designed the fan body and airflow path together with Zojirushi to improve the performance of Japan's energy-efficient motors and the overall performance of air purifiers.

In the future, the Japan Dec Group will continue to be the world's leading comprehensive motor manufacturer, and will continue to introduce products and solutions that cannot be imitated by other companies to meet the needs of customers and society.
