Arun Liao

As DTAF’s Chief Engineer, I have 30 years of experience in HVAC and air purification, specializing in central HVAC system integration and high-efficiency air filtration for commercial and industrial applications. My expertise includes indoor air quality (IAQ), energy efficiency, and reliable system performance, with experience in healthcare, education, and manufacturing facilities. My responsibilities span the full technical process, from product development and compliance validation to on-site commissioning and performance monitoring. I believe good engineering goes beyond laboratory test results. What matters is how a system performs under real operating conditions—maintaining stable performance, requiring minimal maintenance, and meeting the specific needs of each site over the long term. This is the engineering standard we apply at DTAF.
