“Fahsai” means clear sky. It is a city-level air purification tower developed by Research & Innovation for Sustainability Center (RISC) under MQDC. The first “Fahsai” city-class air purification tower was installed at 101 True Digital Park in 2020, to respond to rising air pollution and intensifying PM2.5 issues across Thailand. The second location now is at Makassan Station. RISC by MQDC just launch the second generation Fahsai 2.
Assoc. Prof. Dr. Singh Intrachooto, Chief Advisor to RISC, said that RISC by MQDC is following its “sustainnovation” principle for the well-being of all life on earth.
Fahsai 2 is launched as a second-generation hybrid automatic city-level air purification tower to help address air pollution, especially PM2.5 dust and airborne germs under RISC’s 7 Research Areas in line with UN Sustainable Development Goals (SDGs) for Good Health and Well-Being, Clean Water and Sanitation, Sustainable Cities and Communities, and Life on Land.
Fahsai 2 is a hybrid system. Solar panels reduce its electricity demand during the day to promote well-being and sustainability. The machine improves on Fahsai 1 with its enhanced ability to kill bacteria, fungi, and viruses with UV and ozone.
The fans have been increased from 15,000 cubic meters/hour to 30,000 cubic meters/hour with 4 blades for a total of 120,000 cubic meters/hour to cater for an area of about one football field.
- The fan has been repositioned to prevent reverse airflow
- The moisture trap at the air outlet has been redesigned to prevent water spray being blown out
- The solar panels have an adjustable design to direct clean air farther and more effectively
- The solar panels unfold to collect sunlight during the day and shut at night, when lighting comes on to enhance safety in the surrounding area
Where can you see Fahsai?
The State Railway of Thailand (SRT) and the Don Mueang–Suvarnabhumi–U-Tapao high-speed railway, along with RISC by MQDC, have installed Fahsai 2 at Makkasan Station Airport Rail Link, an area that has high PM2.5 because of heavy traffic and 10,000 daily visitors for services including the subway and the Airport Rail Link.
