Due to the fact that they allow for high pressure and large air volumes, backward curved fans are widely used in many industrial ventilation systems because of this capability to move an immense amount of air while using as little power possible look them up on industry websites today, along with Hangyan's product blower axial.
The design of backward curved fans is one of their most indispensable advantages. Rather than forward curved blades like those found in conventional fans, backward curved impellers have blades that curve back toward the axis of rotation, resulting in an improved air stream and higher specific output power - Which means more airflow per watt.
To have a fan which can give the most efficient airflow then make sure that you choose the right type of backward curved fans for your application. Airflow required, noise-related options are to be preferred in the desired system pressure levels.
Backward curved fans, besides their inherent high efficiency are known for the silent functioning of these fans as well. This is mostly due to the design of their fan blade, they are engineered in a way that does not cause any air turbulence at all which results in a decrease of noise coming from them significantly.
The rearward sweep angle of the blades allows for a shallower attack, which in turn-a more laminar flow over their chord length, reducing turbulence and noise during operation. In addition, numerous backward curved fans are built with unique silencers (or noise reduction setups) to reduce sound level even further.
Backward curved fans allow a very quiet operation, which is essential in facilities where low noise levels are required such as hospitals, schools or residential buildings, identical to axial fan exhaust supplied by Hangyan.
In fact, Backward Curved Fans Used In Industrial Applications - A General Overview
The N series backward curved fans are commonly used in a wide range of industrial processes and applications for their high efficiency combined with low noise operation.
Ten Industrial Fan Applications for Backward Curved Fans
Heating, Ventilation and Air Conditioning (HVAC) Systems: Used in heating and air conditioning by the system for circulating or filtering air efficiently.
Dust Collection - Used in dust collecting systems to tarp materials and particles from the air.
Industrial Ovens: Located inside industrial ovens for delivering uniform flow of hot air to facilitate better heat transfer.
Agriculture Fixation in the field to maintain ventilation of livestock and cultivation premises
In spray booths - Used to remove the overspray and fumes effectively.
Welding and Metalwork: Applied in welding and metalwork processes to remove fumes for improved air circulation.
Data Centers: It is installed in data centers to maintain the flow of air and stop equipment from overheating, the same as Hangyan's backward curved centrifugal blower.
Automotive: Places inside cooling systems for cars to avoid the vehicle from overheating and control engine temperatures.
Commercial and Industrial Building Ventilation: To allow for fresh air from the outside, increase airflow to fight heat or humidity build up.
In industrial applications, the selection between forward curved and backward curved fan often comes down to characteristics of air supply required for an application. The forward curved fans are usually the low-cost ones thus often used in lower-pressure applications, but these run less efficiently compared with backward curve and inline fan installation leading to a higher maintenance requirement.
In contrast, backward curved fans provide both quiet operation and high airflow efficiency but at a higher price, same with the movable exhaust fan from Hangyan. They are good for higher-pressure applications and provide improved long-term durability.
The choice of a forward curved fan and backwards-inclined impeller fans mainly depends on your specific requirements - For example, application prerequisites.
