Single inlet forward curved centrifugal fans

Single inlet centrifugal fans are ideal for applications that require a focused airflow stream, high static pressure, and a relatively low volume of air.

One of their key advantages is the ability to maintain a constant airflow even when resistance in the ductwork or system changes—thanks to their constant flow capability. This makes them particularly suitable for precise and controlled ventilation scenarios.

ADVANTAGES

Directed Airflow with Scroll Casing

The scroll casing is designed to guide and direct airflow efficiently. It plays a crucial role in converting dynamic (velocity) pressure into static pressure, enhancing overall fan performance.

Low Noise Level

Forward curved blade impellers generate the same pressure as backward curved ones but operate at lower rotational speeds. This results in significantly quieter performance.

Constant Flow Option

The constant flow feature ensures that the fan maintains a steady airflow, even when system resistance changes—such as when filters become dirty.

Motor Options for Single Inlet Centrifugal Fans

Axial fans can be fitted with different types of motors—AC, EC, or DC—making them versatile for various power supply requirements. Among these, the EC (electronically commutated) motor is the most cost-effective and energy-efficient choice. This brushless motor delivers superior performance, high efficiency, and simple control, resulting in substantial long-term energy savings.

Known for its reliable and quiet operation, the EC motor also meets current environmental regulations. Axial fans with EC motors are especially suited for applications that demand high airflow and operate efficiently in low static pressure conditions.

Technology

Airflow

In axial fans, the impeller rotates along an axis that runs in the same direction as the airflow. The fan’s aerodynamic blades guide the air to flow straight along the axis of the spinning motor.

Motor

The motor is the central element of an industrial axial fan, directly influencing the airflow and static pressure the fan can produce. The motor’s power must be appropriately matched to the impeller.

APPLICATIONS

Our axial fans offer versatile solutions suitable for both industrial and commercial applications. Their compact design makes them easy to incorporate into existing setups, and their specifications can be customized to meet specific performance needs.

They are available in multiple configurations—such as with or without protective grilles, with mounting plates, and in either suction or blowing versions—allowing flexibility for different system designs. Compact EC axial fans are ideal in situations that demand high airflow with low resistance. Their optimized motor and control systems ensure efficient airflow management. These fans are commonly used in refrigeration, HVAC, ventilation, and renewable energy systems.
