A Single Inlet Single Width (SISW) blower is a type of centrifugal fan known for its simple yet efficient design. With a single inlet and a single-width impeller, this blower generates airflow by accelerating air radially outward from the center of the impeller. SISW blowers are widely used in HVAC systems, industrial processes, and ventilation applications where moderate to high airflow and pressure requirements are needed. They are known for their reliability, compact size, and ease of installation. Additionally, SISW blowers can be customized to meet specific performance specifications, making them versatile solutions for various air handling needs.
