Extremely robust tubular axial fans
Tubular axial fans with cast aluminium impellers.
Fan:
• Airflow direction from motor to impeller.
• Cast aluminium impellers.
• Support ring in sheet steel with double flange and cable glands for entry.
Motor:
• Motors with IE3 efficiency for powers equal to or greater than 0.75 kW, except single-phase, 2-speed and 8-pole.
• Class F motors with ball bearings. IP55 protection. Except single-phase models from size 45 to size 56, with IP54 protection. 1 or 2 speeds depending on model.
• Single-phase 230 V 50 Hz and three-phase 230/400 V 50 Hz (up to 4 kW) and 400/690 V 50 Hz (powers greater than 4 kW).
• Working temperature: -25 ºC +50 ºC.
Finish:
• Anti-corrosive finish in polyester resin, polymerised at 190 ºC, after degreasing with phosphate-free nanotechnology treatment.
On request:
• Airflow direction from impeller to motor.
• 100% reversible impellers.
• Fibreglass reinforced polyamide PL version impellers.
• Special windings for different voltages.
• ATEX certified Category 2.
