Efficient Airflow for HVAC and Industrial Ventilation

Backward inclined centrifugal fans are designed to provide efficient and reliable airflow for HVAC and industrial ventilation systems. Their blades curve backward against the direction of rotation, helping the fan achieve efficient airflow while offering better resistance to dust and debris in the air.

As Backward Inclined Centrifugal Fans Manufacturers in Assam, we provide engineered fan solutions for air handling units, ducted supply and exhaust systems, and industrial process ventilation. These fans are available in different sizes, configurations, and material options to meet specific airflow, static pressure, and site requirements.

What Are Backward Inclined Centrifugal Fans?

Backward inclined centrifugal fans use blades that curve backward relative to the direction of rotation. This design is generally used in HVAC and industrial ventilation applications where efficient air movement and reliable operation are required.

The backward-curved blade arrangement provides good resistance to dust and debris in the air. This makes these fans appropriate for industrial environments where the air may contain dust, process debris, or other contaminants.

These fans may be provided in different configurations so that the system may be matched to the requirements of the connected ventilation or air-handling system.

How Backward Inclined Centrifugal Fans Work

Air enters the fan through the inlet and reaches the rotating impeller. As the impeller rotates, the backward-inclined blades accelerate the air and move it outward using centrifugal force. The air is then directed toward the discharge outlet.

The backward blade design helps provide efficient airflow and reliable performance. It is especially useful for applications where the fan needs to handle air containing dust and debris.

The Assam range includes DIDW centrifugal fans, SISW centrifugal fans, and plug fan configurations for different system requirements.

Available Fan Configurations

DIDW Backward Inclined Fans

The Double Inlet Double Width configuration allows air to enter the impeller from both sides. The available DIDW range includes FABI F Series, FABI P Series, and FABI Q Series.

These configurations can be selected according to the specified airflow, static pressure, and application.

SISW Backward Inclined Fans

The Single Inlet Single Width range includes FABISB Series and FABISD Series. These fans are appropriate for systems in which a single-inlet arrangement is required.

Plug Fans

Plug fan configurations also are available for applications where the fan needs to be integrated directly into an air-handling or ventilation arrangement.

Applications of Backward Inclined Centrifugal Fans

Air Handling Units

Backward inclined fans may be incorporated into air handling units to offer the specified airflow for heating, cooling, filtration, and air movement systems.

Ducted Supply Systems

These fans can deliver air through connected duct networks. Proper fan selection helps maintain the required airflow and pressure throughout the system.

Ducted Exhaust Systems

Backward inclined centrifugal fans can also be used for exhaust applications where unwanted air needs to be extracted from industrial or commercial areas.

Industrial Process Ventilation

Industrial processes often require continuous ventilation to control heat, dust, and unwanted air. The backward-curved blade design provides suitable resistance to particles for many industrial applications.

The current Assam page particularly lists air handling units, ducted supply and exhaust systems, and industrial process ventilation as key applications.

Benefits of Backward Inclined Centrifugal Fans

A properly selected backward inclined fan can offer several practical advantages:

  • Efficient airflow for HVAC systems
  • Better resistance to dust and particles
  • Suitable for commercial ventilation
  • Multiple size options
  • Different material choices
  • DIDW and SISW configurations
  • Plug fan option
  • Suitable for supply and exhaust applications
  • Useful for high-pressure airflow requirements
  • Can be selected according to specific project conditions

Actual fan performance depends on airflow, static pressure, system resistance, installation conditions, and correct system selection.

Backward Inclined Centrifugal Fans Suppliers in Assam

As Backward Inclined Centrifugal Fans Suppliers in Assam, we provide different fan configurations for HVAC, industrial ventilation, and process applications. Fan selection can be based on airflow, pressure, application, material requirement, and installation conditions.

Assam has a diverse industrial environment, including tea processing units across the Brahmaputra Valley, refineries, oil and gas installations, cement plants, food-processing facilities, hospitals, and commercial buildings. The state's heavy monsoon and high humidity can make corrosion-resistant construction and reliable ventilation important concerns for certain applications.

For such projects, the right fan configuration and material may be selected according to the actual operating environment.

The fans supplied for Assam projects are manufactured at the FanAir facility in Neemrana, Rajasthan. Each unit is selected according to the required airflow, static pressure, application, and location conditions.

Technical data and sizing support may be supplied before ordering. Finished equipment can be dispatched to project locations across Assam and other parts of India.

How to Choose the Right Backward Inclined Centrifugal Fan

Choosing the proper fan requires attention to the entire ventilation system.

  • Airflow requirement: Determine the required CFM for the application.
  • Static pressure: Calculate the pressure required to overcome duct and system resistance.
  • Fan size: Select the appropriate diameter according to the required performance.
  • Configuration: Choose DIDW, SISW, or plug fan according to the system design.
  • Material: Select GPSP, SS304, or SS316 according to the operating environment.
  • Application: Identify whether the fan will be used for supply, exhaust, AHU, or process ventilation.
  • Dust conditions: Consider the quantity of dust or particles present within the airflow.
  • Installation: Check available space, accessibility, and maintenance requirements.
  • Site conditions: Consider humidity, temperature, and other environmental factors.

Providing proper airflow, static pressure, application, and site data helps ensure that the selected fan fits the ventilation system.
