HF series circular duct fan is a new type of fan designed by introducing advanced technology from abroad. It is matched by an external rotor backward inclined centrifugal fan,and its shell is made of fire-retardant material by injection molding. The air inlet and air outlet can be connected with circular duct of the same diameter. The installation is simple, which can greatly save the cost of duct design and installation.
The utility model has the advantages of large air volume, high pressure, low noise, small vibration, low power consumption, long life, small volume, light weight, stable operation, etc.Its appearance is beautiful, it can effectively adjust the air, control the hot air, remove the damp, dust, peculiar smell and clean. In addition, the indoor air is fresh, which has gradually replaced the traditional exhaust axial-flow fan, which makes up for the lack of static pressure of the axial-flow fan.
