Used and Surplus Centrifugal Fans

How Does a Centrifugal Fan Work?

A centrifugal fan, also known as a radial fan, works by converting kinetic energy into potential energy to move air or gas in a radial direction. Here is a step-by-step explanation of how a centrifugal fan works:

• The impeller: The centrifugal fan consists of a rotating impeller, which is typically housed within a cylindrical casing. The impeller has a series of blades or vanes that are set at an angle to the plane of rotation. When the impeller rotates, it generates kinetic energy, which is transferred to the air or gas that passes through it.
• The inlet: The air or gas enters the centrifugal fan through an inlet or suction port, which is located near the center of the impeller. As the impeller rotates, it creates a low-pressure area at the inlet, which draws the air or gas into the fan.
• Centrifugal force: As the air or gas is drawn into the impeller, it is accelerated radially outward by the rotating blades. This creates a centrifugal force, which causes the air or gas to move in a circular path around the impeller.
• The volute: The circular path of the air or gas is contained within a volute, which is a curved, stationary housing that surrounds the impeller. The volute gradually increases in size as it approaches the outlet, which helps to convert the kinetic energy of the air or gas into potential energy.
• The outlet: The air or gas exits the centrifugal fan through an outlet or discharge port, which is located at the outer edge of the volute. As the air or gas exits the fan, its velocity decreases, and its potential energy increases, resulting in a high-pressure, high-volume airflow.

Types of Centrifugal Fans and Blowers Offered by JM Industrial

We currently stock and provide the following types of used industrial centrifugal fans for sale, which are designed based on how gas is introduced into the device.  Our inventory comprises the following types of fans:

• Backward Inclined Fans and Blowers: These fans possess blades, which operate away from the direction of wheel rotation. The fans of this type may be equipped with three types of blades – curved single thickness, flat single thickness, and curved airfoil. At static pressures, these fans can produce high to medium airflow. Owing to their high operating speeds, they are preferred over fans listed here.
• Radial Blade Fans: These fans are also known as paddlewheel fans, and they comprise impellers with blades that extend in the perpendicular direction of the rotation of the wheel. The blades in this type of fan are equally placed. The blades of this fan are narrower, heavier, and deeper than other fan types here. These fans can produce high to medium flow. They can move high mass or volume of fluid and are ideal for material handling industries.
• Radial Tip Fans: The blades are backward curved, but they are cupped in the wheel rotations direction. They work similar to backward inclined fans, moving high mass and fluid. These fans are generally preferred for high flow rate applications. These fans are generally used in standard ventilation applications or dust collection systems.
• Inline Centrifugal Fans: These fans feature backward inclined type wheels, which are enclosed in a casing. This casing is tube-axial type. Inline centrifugal fans are generally chosen for medium-duty applications.
• Forward Curved Blowers and Fans: These fans feature squirrel cage wheels, which is why they are known as squirrel cage fans. Forward curved fans feature impellers with small and curved blades, which are curved in the wheel’s rotational direction. They are employed for low pressure and low speed applications in central station units, domestic furnaces, and packaged air conditioning units.
• Centrifugal Exhaust Fans and Blowers: These type of fans are mechanical devices used to move air or gases in a particular direction using a rotating impeller or blade. These devices are commonly used in industrial, commercial, and residential settings to exhaust or ventilate air, remove pollutants or fumes, and regulate temperature and humidity levels.

How Centrifugal Fans & Blowers Improve Material Handling Efficiency?

Centrifugal fans and blowers are commonly used in material handling applications to improve efficiency by moving materials more quickly and effectively. Here are several ways used centrifugal fans and blowers can improve material handling efficiency:

• Increased airflow: Centrifugal fans and blowers can provide high volumes of airflow, which can be used to move materials through a processing system more quickly. This increased airflow can also help to prevent blockages and other issues that can slow down the material handling process.
• Improved pressure control: Industrial Centrifugal fans and blowers can be used to control the pressure within a material handling system, which can help to optimize the flow of materials and prevent damage or wear and tear on equipment.
• Enhanced dust collection: Many material handling applications generate dust or other airborne particles that can be hazardous to worker health and safety. Centrifugal fans and blowers can be used to collect and remove these particles, improving air quality and reducing the risk of respiratory issues.
• More efficient conveying: Industrial Centrifugal fans and blowers can be used to move materials over longer distances and at higher rates of speed, reducing the need for manual labor and improving overall efficiency.
• Increased product quality: In some material handling applications, the quality of the product can be compromised by excessive handling or exposure to dust and other contaminants. By improving airflow, controlling pressure, and collecting dust, centrifugal fans and blowers can help to preserve product quality and reduce waste.
