BACKWARD CURVED IMPELLERS

MAXIMUM EFFICIENCY, MINIMUM NOISE

Impellers designed to cover the needs of systems requiring air volume and pressure: HVAC, ventilation, plug fan, industrial equipment and machinery, agricultural machinery and other industrial uses.

  • High efficiency and low noise levels.
  • Manufactured by means of a welding process or using tabs in different materials and finishes.
  • Impeller diameters from 225mm to 1000mm.
  • Connection to the motor’s shaft by means of bushings or taper-lock bushing.
  • Optional reinforced impellers for increased pressure and temperature.
  • Temperatures ranging between  -20ºC and 300ºC continuously.
