The DFBZ series fans use a low-noise fan-specific motor direct drive; the whole machine is square, beautiful in appearance, and the wall is reserved with square holes for easy installation; the air outlet is equipped with self-hanging shutters to prevent outdoor rainwater and natural wind from flowing back into the room: it has obvious advantages such as firm installation, low vibration, low noise, and stable operation. It is widely used in industrial and mining enterprises, civil buildings, gymnasiums, animal husbandry, and various entertainment venues. The DFBZ-I type adopts an inner rotor motor direct drive structure, the DFBZ-II type adopts an inner rotor motor and a belt drive structure, and the DFBZ-III type adopts an outer rotor motor direct drive structure. It can be made into an anti-corrosion and explosion-proof type according to user requirements. Axial flow fan, also known as a local ventilator, is an airflow in the same direction as the shaft of the fan blade (that is, the wind flow direction is parallel to the shaft), such as electric fans and air conditioner outdoor fans, which are axial flow fans. It is a fan commonly used in industrial and mining enterprises, which is different from ordinary fans. The motor and blades of a conventional axial flow fan are in a cylinder, and the appearance is a cylinder. It is used for local ventilation, easy to install, and has obvious ventilation and ventilation effects. It is safe and can be connected to the wind tube to send the wind to the designated area.

 

 The biggest difference between a square axial flow fan and a conventional axial flow fan is that the motor and blades of a square axial flow fan are in a cylinder, and the appearance is square, which is easier to install than a cylindrical fan. The principle is to use the cooling principle of air convection and negative pressure ventilation. 

 

Fresh air is naturally inhaled from the opposite side of the installation location-the door or window, and the indoor hot and humid gas is quickly forced to be discharged to the outside. Any poor ventilation problem can be improved, and the cooling and ventilation effect can reach 90%-97%. 

 

1.Product features of square axial flow fan:

 

 The whole machine adopts CAD/CAM design, with low investment cost, large air volume, low noise, low energy consumption, stable operation, long life, high efficiency, etc. The shutters are automatically opened and closed to achieve dustproof, waterproof, beautiful and generous; it can blow air, which is the best choice for cooling and ventilation of modern factories, and can also be used for exhaust.

 

 Environmentally friendly and energy-saving square axial flow fans will become the mainstream of the ventilation and cooling equipment market. 

 

2.Application scope of square axial flow fans: 

 

1.For ventilation: installed outside the workshop window, generally choose the downwind outlet, exhaust air outward, and extract odorous gases; generally chemical plants and other applications are more common. 

 

2.Used with wet curtains: used to cool the workshop in the hot summer, no matter how hot your workshop is, the wet curtain-negative pressure fan system can reduce the temperature of your workshop to about 30C, and there is a certain humidity. 

 

3. Square axial flow fans are used in: workshops with high temperature or odor: such as heat treatment plants, casting plants, plastic plants, aluminum profile plants, shoe factories, leather factories, electroplating plants, and various chemical plants. Suitable for labor-intensive enterprises: such as garment factories, various assembly workshops, and Internet cafes. Ventilation and cooling of horticultural greenhouses and cooling of livestock farms. Especially suitable for places that require cooling and a certain humidity. Such as cotton mills, wool mills, linen mills, weaving mills, chemical fiber mills, warp knitting mills, texturing mills, knitting mills, silk weaving mills, socks mills and other textile mills. Suitable for warehousing and logistics fields.
