Brick Kiln Boiler Centrifugal Blower Fan CE Certification Energy Saving
The main features of the fan are: high fan efficiency, high total pressure, low noise, flat performance curve, wide economical use area, and the use of backward-type blades. The full-pressure efficiency of the fan at the optimum working point is 86.5% noise index ( Compared with A sound level) LS = 11.5 decibels, these two indicators are the best level compared with the current domestic industrial boilers.

Main Features
1) The fan has a high pressure and the air outlet can generate a lot of energy.
2) The motor and impeller are connected by a bearing housing and a rolling bearing is used.
3) The bracket is fixed by steel plate, which can effectively reduce vibration.
4) The bearing is equipped with a yellow protective cover for protecting the bearing.
5) The motor is well-known in China and has the advantages of high efficiency and energy saving.
Type
1. Both the ventilator and the induced fan are single inhaled; there are six types of ventilator, 4.5N 5.6g / 7.1g / 912.5.
2. the draft fan can be made into two types: left rotation or right rotation. The fan is faced squarely from one end of the transmission group, for example, the impeller rotating clockwise is called right rotation, expressed as "right", counterclockwise rotation is called left rotation, and it is expressed as "left".
3. The air outlet position of the fan is expressed as the outlet angle of the housing. "left" and "right" can be made into three angles: 0 degrees 90 degrees and 180 degrees.
4, the transmission mode of the fan is A, C, D.
Advanced Process
All steel laser cut blades are welded and positioned accurately. The overall strength of the blades are designed and welded to withstand long hours high speed operation.
Optimized Design
The fan adopts advanced technology. The design of backward curved centrifugal wheel is optimized by means of CFD hydro-field simulating. The design is more accordant with the aerodynamic characteristics, high efficiency, and stable airflow.
Good wear resistance
The flow stability of the fan is good and the impact of air flow and medium on the blade is reduced.
