The impeller features blades with a symmetrical wing profile for reversible models and a non-symmetrical airfoil profile for unidirectional versions. The blade pitch can be adjusted when the fan is stopped.

Blades are made of Silumin (Al Si 10 Mg) aluminum alloy (UNI 1706 EN AB 43100), while the hub includes a steel or cast-iron insert allowing direct shaft coupling.
Each blade undergoes X-ray testing (ASTM E155) to ensure structural integrity and detect any internal casting defects.

The cylindrical casing is made of heavy-duty steel, with stiffening flanges on the inlet and outlet sides according to ISO 6580. Inspection doors are available on request.
The structure is reinforced to avoid resonance at operating frequencies and is prepared for vibration sensor installation.

Available materials and finishes:

• Hot-dip galvanized carbon steel
• Painted carbon steel
• Hot-dip galvanized + painted carbon steel

The AXL Series is equipped with a three-phase asynchronous induction motor with squirrel-cage rotor, compliant with IEC 34-1, 34-5 and 34-6 standards.
Designed for direct start and continuous operation, the motor supports frequency converter control.

Key features:

• Insulation class H or F, depending on emergency temperature rating
• External terminal board connected via flexible conduit

Toroidal-shaped nozzle with protection grid to facilitate the entry of air by reducing the entrance losses and improving the performances of the fan.

Designed to regulate or shut off airflow, the damper can be installed at the fan inlet or outlet and supplied with manual or motorized actuation.

Silencers designed to reduce the noise generated by the fan and the airflow while keeping pressure losses to a minimum. They can be installed on the inlet and/or outlet side and are available in different lengths and configurations according to the acoustic requirements of the project.

Designed to recover static pressure and reduce airflow velocity, diffusers improve aerodynamic efficiency and can be installed at the fan inlet or outlet.

Consisting of anti-vibration spring shock absorbers made of UNI 7900 harmonic steel fitted with containment disks and steel spring coated with a vulcanized anti-oil elastomeric mix. The springs are positioned under the plinth and they allow more than 80% vibrations dumping.
