advantage:

· The material selection is reasonable, ensuring stable operation and long service life.
· The fan structure is flexible and can be selected according to different needs of users; there are 4 kinds of air outlet direction: 0°, 90°, 180°, 270°; pulleys can be installed on the left and right sides of the fan shaft.
· According to the fan speed,the size of the shaft,the bearing of the model and the structure of the wheels can be adjusted  to achieve higher total pressure and larger air volume.
· Bearing case structure for oil-bearing heavy-duty double-row ball bearings
· High pressure, high efficiency, low noise, good safety and strong ventilation.


application:

· It is widely used in various types of cabinet-type central air-conditioning units, pipeline units and other equipment for HVAC, purification, ventilation and other equipment.
· It can be delivery the air at the tempeture of -20°C~85°C and the relative humidity is 5%~95%.Non-flammable, not corroded.
