Understanding the different types of HVAC fans is essential for optimizing system performance, energy efficiency, and indoor comfort. The right fan selection can significantly impact airflow, temperature regulation, and overall system longevity.

At EDI, we offer a comprehensive range of fans tailored to meet diverse HVAC requirements, ensuring that each system runs at its optimal capacity while maintaining energy efficiency and reliability. Whether for commercial, industrial, or residential applications, our high-quality fan solutions help enhance performance and create a more comfortable indoor environment.

1. Axial-Flow Fans

    Axial-flow fans move air parallel to the fan’s axis, effectively handling large volumes of air at low pressure. These fans are commonly used in applications such as ventilation, air conditioning, and industrial processes. With their simple design and efficient airflow, axial fans are ideal for systems where space constraints are not an issue. At EDI, our selection of axial fans is designed to meet the demands of various HVAC systems, ensuring smooth, efficient airflow and consistent system performance.

    2. Centrifugal Fans

      Centrifugal fans, also known as radial fans, move air perpendicular to the fan’s intake, increasing air pressure and velocity. These fans are typically used in HVAC systems that require higher pressure, such as ducted systems, air pollution control equipment, and systems that need to overcome resistance from filters or longer ducts. Our centrifugal fans are engineered for durability, efficiency, and long-lasting performance, making them suitable for a wide range of industrial applications that demand high airflow and pressure.

      3. Mixed-Flow Fans

      Mixed-flow fans combine features of both axial and centrifugal fans, offering a balance between airflow volume and pressure capabilities. These versatile fans are designed to handle medium pressure and airflow, making them ideal for commercial HVAC systems and residential ventilation. The mixed-flow design provides better efficiency compared to pure axial or centrifugal designs, allowing these fans to perform well in a variety of conditions. At EDI, our mixed-flow fans are designed to offer efficiency and versatility across a range of HVAC applications, ensuring energy savings and improved comfort.
