What are the current applications of indirect centrifugal fans?

Currently, the use of industrial centrifugal fans is highly applied in dust extraction, exhaust gas extraction, cooling ventilation, fresh air supply, fire prevention, etc.

Especially in harsh industrial environments such as high temperatures, toxic emissions, large concentrations of dirt, etc. The current optimal solution is to use industrial fans to suck away exhaust gases. , dirt, high-temperature gas... An indirect centrifugal fan is the right choice today. Let's learn more about indirect centrifugal fans now.

The harsh working environment makes machinery, equipment, and even human health seriously degraded. Without the appearance of indirect centrifugal fans, surely, no one would dare to work in these high-temperature, humid environments anymore. So what is an indirect centrifugal fan? What characteristics do they have that make them so good to use in particularly harsh conditions? Let's learn about this product with us!

What is an indirect centrifugal fan?

An indirect centrifugal fan is a kind of industrial centrifugal fan. They have an indirect drive structure because the motor is separate from the fan, and is connected to the impeller through bearings, bearings, belts, or stiff joints.

Unlike direct centrifugal fans, centrifugal fan motors are designed to be separate from the fan's drive line, helping the motor avoid contact with hot air, high temperature, acidic vapors, etc. The engine is more durable, increases its service life, and operates for a long time in harsh environments.

Thus, in harsh environments, indirect centrifugal fans are often used.

Operational features

In terms of operating mechanisms, indirect centrifugal fans are similar to direct centrifugal fans. The only difference is that when an electric current flows through, the motor will cause the movement of the belt and the drive bearings. From there, mechanical energy is generated by the propeller to help the propeller rotate and create wind.

However, the drive through the belt reduces a part of the fan's suction compared to the direct centrifugal fan line.

Therefore, when choosing indirect centrifugal fans, it is necessary to survey the environment and use needs to choose a fan with appropriate capacity, pressure, and flow. Avoid the situation of choosing a fan that is not according to specifications, causing the use of an inefficient fan, and wasting investment costs...

Application of indirect centrifugal fan

Indirect centrifugal fans are used for many different environments and spaces. For example the following applications:

Exhaust gas, hot air

Many industrial plants generate large amounts of waste gas and heat such as thermal power plants, industrial boilers, etc. Here, toxic emissions are regularly generated, causing direct and direct environmental pollution. affect human health. Thanks to the use of centrifugal fans, it is possible to suck the exhaust air out through the air duct. In addition, it is possible to combine the installation of exhaust gas treatment systems to filter exhaust gases before discharging them into the environment.

Vacuuming

Cement factories, wood factories, food factories, paper factories… many other types of industrial plants. These are places where large amounts of dust are generated. This amount of dust directly affects the activities in the factory, affects the health of workers, and affects the surrounding environment. Indirect centrifugal fans can be installed in conjunction with dust treatment systems to collect and filter dust. Help the space become airy and clean, and protect the health of workers.

Fresh air supply, ventilation

Thanks to strong suction and thrust, indirect centrifugal fans can be used for ventilation and fresh air supply. To help the environment become cool, and clean, the air is circulated.

Thus, it can be said that indirect centrifugal fans are important industrial equipment, applied to many industries today. In particular, this is a device that brings many important benefits for protecting human health and protecting the environment.

Thus, this article has provided some information about indirect centrifugal fans and the application of indirect centrifugal fans. Hope the article brings a lot of useful information for readers.
