T30-11 type axial flow fanDetailed product description：

T30-11 Axial Flow Fan Performance and Characteristics:

The T30-11 axial flow fan can be used in metallurgy, kiln factories, steel rolling, chemical, textile, cold storage, canteens, grain depots, breeding farms, tunnel heads, warehouses, residential areas, and other places. For ventilation or enhanced heat dissipation purposes, if the casing is removed, it can also be used as a free fan or installed in series at intervals in longer exhaust ducts to increase the total pressure in the ducts. The characteristics of this fan are complex structure, low noise, and a wide range of power consumption options.

The diameter of the fan impeller ranges from 250-1000 millimeters, and the ratio of the impeller disc diameter to the impeller diameter is a=a/D=0.3. It is classified into ten types according to the machine number, including NO.22/2, 3, 31/2, 4, 5, 6, 7, 8, 9, and 10. Each machine number has 4 or 6 blades, which can be installed at six angles including 10o, 15o, 20o, 25o, 30o, and 35o. Each machine number has different wind pressure, air volume, and power consumption due to variations in the number of blades, blade installation angles, and spindle speed.

Under the condition that the blade circumferential speed does not exceed 60 meters per second, various electric motors are selected to directly connect with the impeller shaft. The body shell is cylindrical. Facing the direction of the air inlet, the direction of blade rotation is counterclockwise.

The blade sizes of each unit number of T30-11 axial flow fan are similar, and the blades are made of thin steel plates. The wind duct and bracket are made of steel plates and profiles. NO.21/2、 3. 31/2, 4, 5, 6, 7, and 8 use two types of speed motors, NO.9、 Only one type of speed motor is used. The maximum air pressure of this type of ventilation fan can reach 39 millimeters of water column, and the maximum air volume can reach 48000 cubic meters per hour. If used in longer exhaust pipes, it can be installed in series at intervals to increase the air pressure in the pipes.
The gas passing through the ventilation fan should be non corrosive and free of significant dust, and its temperature should not exceed 45 ℃.
