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.
