PM 2.5 Dust that people in Bangkok and nearby provinces are currently facing is a problem that is becoming increasingly severe over time. It is well-known that air pollution directly impacts public health. Recently, the Research and Innovation for Sustainability Center (RISC) by MQDC, in collaboration with NESTECH Thailand Co., Ltd., has developed the 'Fah Sai', Thailand's first urban air purifier prototype aimed at cleaning polluted air and eliminating harmful PM 2.5 dust using highly efficient technology. This aligns with the strategy of Magnolia Quality Development Corporation Limited (MQDC) regarding ‘for all well-being’, which seeks to create a sustainable improvement in living conditions for everything on this planet.

     

       'Fah Sai' is located at Family Park in the 101 True Digital Park project. It is a hybrid automatic air purifier tower developed from a PM 2.5 dust collection system, integrating a hybrid energy system that utilizes a 3,850-watt solar panel along with a battery system, thereby reducing reliance on external electrical power sources. The operation begins with high-speed fans drawing air into the system and separating large and small dust particles using wind speed and water mist for a three-layer dust capture process, followed by a Jet Venturi Scrubber system. The entire system uses 70 liters of water, allowing it to purify air at a maximum rate of 120,000 cubic meters per hour. An intelligent system controls the fan motor's operation according to dust concentration until PM 2.5 levels drop to normal thresholds.

Assoc. Prof. Dr. Sing Intarachuto, Head of the Advisory Committee at the Research and Innovation for Sustainability Center (RISC) by MQDC and Head of the Environmental Design Innovation Center at the Faculty of Architecture, Kasetsart University stated that humans typically breathe 8 liters of air per minute, and the 'Fah Sai' air purifier can provide clean air for over 100,000 people in the surrounding area daily. This tower has a development budget of over 10 million baht to serve as a prototype for urban air purifiers that concretely support solutions to air quality issues, particularly PM 2.5 pollution. The collaboration between RISC by MQDC and NESTECH Thailand Co., Ltd. marks a positive starting point for all sectors to recognize the pollution problems they face and encourages property developers to invest in building air purification towers within residential projects to enhance the environmental quality for residents. RISC is ready to provide consulting on construction and has plans for the continuous development of urban air purifiers, collecting dust data in areas with heavy traffic and high dust levels to inform future research and development of more efficient urban air purifier models.
