About Kool Air International
Kool Air International Development Limited is a Hong Kong-based supplier of industrial and commercial ventilation and cooling systems, and the holder of the exclusive right to export and sell RTFANS products outside mainland China. RTFANS has worked in large-space cooling since 2003; Kool Air's export business began in Hong Kong in 2014. Our current product scope includes HVLS fans, evaporative air coolers, industrial energy-saving air conditioners, cooling pad and ventilation fan systems, and integrated fan-and-cooler combinations.
What should buyers know about RTFANS?
We provide equipment for air circulation and evaporative cooling projects, but product selection should begin with the facility rather than a headline performance claim. Building geometry, climate, heat load, existing ventilation, electrical supply, installation constraints, and destination-market requirements all affect our final recommendation. Buyers should confirm model specifications, supplied documents, responsibilities, and acceptance criteria in the quotation or technical agreement with us.

Manufacturing and Quality
Our products are manufactured by Guangdong Ruitai Ventilation & Cooling Equipment Co., Ltd., the company behind the RTFANS brand. HVLS fans joined the range in 2010, when they were first paired with evaporative cooling. Our Dongguan operating company has held equity in Ruitai and the exclusive export and sales rights outside mainland China since 2019.
Ruitai has a 15,000 m² production base in Dongguan, Guangdong, and more than 100 patents and software copyrights. The manufacturing company's management system is certified to ISO 9001 and ISO 14001; products carry CE, CB, RoHS and CRAA certification. Certificates are held by the manufacturing company and apply to the covered processes and products.

How We Work With You
Minimum order of one unit. Sample orders and mixed pallets are supported. OEM and ODM options include logo, colour, voltage and frequency, plug type, manual language, packaging and private label. Market certification and electrical requirements are confirmed before ordering.
Engineering support includes airflow and coverage calculations, mounting layouts and drawings based on ceiling height, layout and heat load. We provide installation guidance, spare parts and technical documentation. Commissioning support is available in markets with a service partner.
Our commitment
Built for the long operating life of large spaces
Large-space ventilation is not a fashion-driven business. Equipment specified today will still be running in ten or fifteen years, and whoever owns it will remember who supplied it. We have built the company around that timescale: we hold equity in the factory that makes our products, control the export chain end to end, and keep the engineering and the accountability in the same place.
