What Are Backward Inclined Centrifugal Fans?

Backward inclined centrifugal fans use an impeller with blades that curve backward from the path of rotation. As the impeller rotates, air enters through the centre and moves outward through the fan housing.

This design helps the fan handle system resistance while maintaining efficient airflow. Backward Inclined Centrifugal Fans in Delhi can therefore be used in HVAC and industrial applications where strong airflow and pressure are critical.

How Backward Inclined Centrifugal Fans Work

The fan draws air into the centre of the rotating impeller. The backward-curved blades then pass air toward the outside of the fan.

The housing collects the air and directs it into the connected duct system. The final fan must be selected according to the required airflow, static pressure, duct resistance, and operating conditions.

Key Features of Backward Inclined Centrifugal Fans

Backward-Curved Blade Design

The backward-inclined blade design supports efficient air movement and helps the fan work against system resistance. It is appropriate for applications that require consistent and reliable airflow.

Wide Size Range

The available Backward Inclined Centrifugal Fans range from 180 mm to 1120 mm diameter. This provides options for different commercial and industrial ventilation requirements.

High Airflow Capacity

The listed airflow range is 700 to 60,000 CFM, depending on the chosen fan model and configuration.

Different Material Options

The fans are available in GPSP, SS304, and SS316 material options. The appropriate material can be selected according to the application and operating environment.

Applications of Backward Inclined Centrifugal Fans

Backward Inclined Centrifugal Fans in Delhi can be used in many commercial, industrial, and building ventilation applications.

HVAC Systems

These fans may be used in HVAC systems for supply and exhaust applications. They help move air through duct networks in offices, commercial buildings, hotels, hospitals, and other facilities.

Air Handling Units

Backward inclined fans are suitable for air handling units where controlled airflow and pressure are required. The fan size and configuration should be selected according to the AHU design.

Industrial Ventilation

Industrial Centrifugal Fans can be used in factories and industrial facilities in which continuous air movement is required. They can support general ventilation, exhaust, and process air applications.

Ducted Supply and Exhaust

These fans can be used for ducted supply and exhaust systems. Their design lets them move air through ductwork while handling the resistance created by the system.

Benefits of Backward Inclined Centrifugal Fans

One of the primary advantages of a backward inclined fan is its capacity to provide efficient airflow while handling higher system resistance.

The backward-curved blade design also can help offer stable operation in different HVAC and commercial applications. The exact performance depends on the chosen model and operating conditions.

For projects requiring HVAC Centrifugal Fans, proper fan selection is important to achieve the required airflow and pressure.

Backward Inclined Centrifugal Fans Manufacturers in Delhi

When selecting Backward Inclined Centrifugal Fans Manufacturers in Delhi, it's essential to check the complete requirements of the ventilation system.

Airflow, static pressure, fan size, material, installation area, and application should be considered before choosing the final fan. This helps ensure that the fan matches the actual requirements of the project.

The current Delhi product page lists DIDW, SISW, and plug fan configurations, along with FABI F, FABI P, FABI Q, FABISB, and FABISD series.

Backward Inclined Centrifugal Fans Suppliers in Delhi

Reliable Backward Inclined Centrifugal Fans Suppliers in Delhi should be able to provide suitable fan configurations for different HVAC and commercial applications.

Before ordering, customers should share details such as required airflow, static pressure, application, installation space, and material requirements. This information helps in selecting the right fan.

The current FanAir Delhi site notes that these fans are used for air handling units, ducted supply and exhaust systems, and industrial process ventilation.

Backward Inclined Centrifugal Fans Manufacturer in India

An experienced Backward Inclined Centrifugal Fans Manufacturer in India can offer specific sizes and configurations for commercial and industrial ventilation systems.

The fan can be selected according to the required airflow and static pressure. Material options such as GPSP, SS304, and SS316 offer flexibility for different operating environments.

Manufacturing and Quality

Proper manufacturing and balancing are crucial for centrifugal fan performance. The impeller needs to be correctly fabricated and balanced as it rotates continuously during operation.

FanAir's current manufacturing information includes CNC laser cutting, dynamic balancing, and aerodynamic performance testing. CFD-based engineering is also used for airflow design and performance optimization.

These procedures help support smooth operation and consistent airflow in different HVAC and industrial applications.

How to Choose the Right Backward Inclined Fan

Before selecting a Backward Inclined Centrifugal Fan, consider:

  • Required airflow in CFM
  • Required static pressure
  • Duct resistance
  • Fan diameter
  • Available installation area
  • Material requirement
  • Air temperature
  • Motor and power requirement
  • Supply or exhaust application
  • Operating hours

These factors help ensure that the selected fan suits the actual system requirements.

Why Proper Fan selection Matters

A fan should be selected according to both airflow and pressure requirements. Choosing a fan only by its physical size may not provide the required performance.

The duct design, bends, filters, dampers, coils, and other components can increase system resistance. Therefore, the complete HVAC system needs to be considered before finalising the fan.

Proper selection helps the fan deliver the required airflow and supports reliable operation.
