Anway Engineering was established in 1982 with the aim of supplying state of the art ventilation and related fire safety equipment to Hong Kong, Macau and China. In 1983, we introduced the first in-line duct fan driven by external rotor motor to the Hong Kong market which has now become a very popular type of fans in every building. In 1985 when smoke control system for fire safety was still in discussion around the world, we introduced the first fire / smoke dampers to UL555S standard to Hong Kong. With the increasing awareness on the importance of air cleanliness in both indoor and outdoor environment, we have expanded our line of representation to include full range of air filtration and purification products. In recent years, the Government has put heavy emphasis in energy efficiency. The pressence of air and dirt in hydrous system has a significant impact in the efficiency and life of heat exchanging equipment.
