Efficient Airflow Solutions for HVAC and Industrial Ventilation

Backward inclined centrifugal fans are designed to move air efficiently through HVAC and industrial ventilation systems. Their blades curve backward against the direction of rotation, helping the fan provide efficient airflow with good resistance to dust and particles present in the air.

Backward Inclined Centrifugal Fans Manufacturers in Ahmedabad provide different fan sizes and configurations for applications that require reliable airflow and high-pressure performance. These fans are suitable for air handling units, ducted supply and exhaust systems, and industrial process ventilation. The appropriate model can be selected according to airflow, static pressure, application, and site conditions.

What Are Backward Inclined Centrifugal Fans?

Backward inclined centrifugal fans use blades that curve backward relative to the path of rotation. This design supports efficient air movement and makes the fans suitable for applications where air may contain dust or debris.

The centrifugal construction allows air to be moved through connected ductwork and HVAC equipment. Different sizes and configurations can be selected depending on the required airflow, static pressure, and installation arrangement.

These fans are commonly used in industrial ventilation and HVAC systems where reliable air movement and high-pressure airflow are required.

Backward Inclined Fan Range

The Ahmedabad range includes fan diameters from 180 mm to 1120 mm, with an airflow range of 700 to 60,000 CFM. Material of construction options include GPSP, SS304, and SS316, allowing the fan to be selected according to the application and operating environment.

The available range offers flexibility for different ventilation requirements. Fan selection should be based on the required airflow and static pressure rather than only the physical size of the fan.

DIDW Backward Inclined Fans

DIDW stands for Double Inlet Double Width. This configuration is appropriate for applications where higher airflow is required within the available equipment arrangement.

The current range includes FABI F Series, FABI P Series, and FABI Q Series. These configurations can be considered for specific HVAC and air-handling requirements depending on system design and operating conditions.

DIDW fans may be integrated into air handling units and other ventilation systems where consistent airflow is required.

SISW Backward Inclined Fans

SISW stands for Single Inlet Single Width. These fans use a single inlet arrangement and may be selected where this configuration fits the ventilation system.

The available SISW range includes FABISB Series and FABISD Series. Selection depends on airflow, static pressure, available installation space, and the requirements of the connected system.

Plug Fan Configuration

Plug fans also are available in the backward inclined fan range. They can be useful where the fan needs to be integrated directly into an air-handling arrangement without a conventional scroll casing.

The suitable plug fan configuration should be selected according to airflow, static pressure, system design, and installation requirements.
