What is another name for the evaporator fan wheel commonly referred to as?

The evaporator fan wheel is commonly referred to as a forward curve fan. This type of fan is designed with blades that curve in the direction of rotation. This design is particularly effective for moving larger volumes of air at relatively low static pressures, making it ideal for use in HVAC systems where the need for effective cooling and air distribution is critical.

Forward curve fans have the advantage of generating a consistent airflow, which is essential in evaporators to ensure even cooling throughout a space. Their design minimizes turbulence and enhances the efficiency of heat exchange in the evaporator coils, contributing to optimal system performance.

Understanding the specific characteristics and applications of forward curve fans can help in selecting the right components for HVAC systems, ensuring they operate efficiently and effectively in managing indoor climates.
