Versatile Performance and Customization

These centrifugal fans offer airflow ranging from 1000 to 45,000 m/hr, with capacities and configurations tailored to your specific requirements. With options for semi-automatic or automatic operation, they support both horizontal and vertical orientations. From component selection to dimensions, customization is available to optimize efficiency and fit your facilitys unique needs.

Built for Durability and Safety

All models are fabricated with robust materials such as mild steel or stainless steel, and feature powder coated or painted surfaces for enhanced longevity. Protection classes up to IP65 shield the motor from dust and water ingress, ensuring extended service life even in challenging industrial environments. Air-cooled, these fans are suitable for operation up to 80C.

FAQs of Direct Driven Centrifugal Fans:

Q: How do I choose between backward curved and forward curved impeller types for my application?

A: Backward curved impellers are ideal for high-pressure, lower airflow applications and offer higher efficiency and quieter operation. Forward curved impellers deliver higher airflow at lower pressures, making them suitable for HVAC and low-pressure ventilation setups.

Q: What installation options are available for these centrifugal fans?

A: Fans can be mounted on the floor, wall, or within ducts, depending on ventilation requirements and spatial constraints. Orientation can be horizontal or vertical to best suit air movement and facility layout.

Q: When should I opt for stainless steel or aluminum blades over mild steel?

A: Stainless steel or aluminum blades are recommended in corrosive or humid environments where durability and resistance to oxidation are critical. Mild steel blades are suitable for standard industrial settings with controlled conditions.

Q: Where are direct driven centrifugal fans commonly used?

A: These fans are widely deployed in industrial ventilation, HVAC systems, factories, dust collection units, and other industrial processes across India that require robust, continuous airflow and reliable motor performance.

Q: What is the process for customizing these fans to fit my facility?

A: Customization involves selecting the appropriate impeller type, capacity, dimensions, materials, and mounting configuration. Provide your requirements for airflow (CFM or m/hr), pressure, and installation to the supplier for tailored design and manufacturing.

Q: How does the direct drive system benefit industrial operators?

A: Direct coupled drive eliminates the need for belts or additional transmission components, reducing maintenance requirements, improving efficiency (up to 82%), and enhancing reliability under continuous operation.

Q: What are the advantages of the powder coated or painted surface treatment?

A: Powder coating or painting provides an extra layer of protection against corrosion and wear, extending the service life of the fan in challenging industrial environments.
