Centrifugal fans are supplied from the factory with a certain orientation that will have been specified by the customer at the time of ordering. This orientation will depend on the application or installation, as well as the maintenance needs with the aim of making it as accessible and easy as possible.
Unless otherwise noted, the default assembling orientation for industrial range of centrifugal fans is LG270.
The orientation of a centrifugal fan
Centrifugal fans are essential devices in various industrial and commercial applications, where the movement of air or gases is required. A crucial characteristic of centrifugal fans is their orientation, which has a significant impact on their performance and suitability for different applications.
The orientation of centrifugal fans is a critical factor that influences the efficiency, installation compatibility, and ease of maintenance of the ventilation system. Understanding and selecting the proper orientation for a specific application is essential to ensure optimal performance and economical operation. By considering the various orientations available, along with the direction of rotation and environmental conditions, an effective and long-lasting ventilation solution can be achieved.
What is meant by orientation in a fan?
The orientation of a centrifugal fan refers to the direction in which air is expelled from inside the fan. The position of the fan and the available ductwork should fit together as simply and easily as possible in order to maximize system performance.
Orientations are commonly classified based on the angle of air outlet from the fan, specified in degrees, taking the view of the motor as a reference.
Importance of orientation in fans
Operating efficiency
Correct orientation of a centrifugal fan is essential to maximize operating efficiency. Proper orientation can minimize head losses and optimize airflow, ensuring the fan performs optimally in your specific application.
Installation compatibility
Fan orientation must be compatible with the duct system design and available installation space. Incorrect orientation can require costly modifications or result in suboptimal performance due to physical or aerodynamic constraints.
Maintenance and accessibility
The choice of orientation also affects ease of maintenance and accessibility to critical fan components. Orientation that allows easy access to maintenance points can reduce downtime and operating costs.

Fanware you can consult the possible orientations for each centrifuge in the fan dimensions section.
Additional considerations
Rotation direction
It is important to consider the direction of rotation of the fan impeller, as this also affects the orientation and airflow. Centrifugal fans can be configured to rotate clockwise (RD orientations) or counterclockwise (LG orientations), and this configuration must be compatible with the selected orientation.
Adaptations for the environment
In environments with extreme conditions, such as high temperatures or corrosive atmospheres, it may be necessary to use special materials and coatings. Fan orientation must be considered to ensure that these adaptations do not compromise the integrity of the system.
