SF cooling fans have been designed for high efficiency and low noise levels during operation. The impeller made of powder-coated sheet metal is directly connected to the motor, ensuring stable operation without the need for frequent maintenance. The steel protective guard secures the user, and the frame construction is based on standard mounting dimensions. Speed adjustment is possible in single-phase versions using a voltage regulator and in three-phase versions with an inverter. The SF series is used in refrigeration systems, laboratories, air conditioning units, and industrial equipment, providing efficient cooling and constant airflow.
