CH

  • Centrifugal fans designed to meet the needs of various industrial sectors.
This series includes two types of impellers: CHA and CHB.
CHA:
  • Comprised of 12 backward-curved “Airfoil” profile blades.
  • Welded at the front to an aerodynamic profile cone and at the back to a flat crown.
  • Efficiencies up to 90% with low noise level.
  • Suitable for moving air or dust-free gases with a relative humidity of less than 80%.
  • Operating temperature up to 300°C.
CHB:
  • Composed of 12 backward-facing flat blades.
  • Welded at the front to an aerodynamic profile cone and at the back to a flat crown.
  • Efficiencies up to 86%.
  • Suitable for moving fluids with fine, dry, non-abrasive dust, with a high percentage of humidity.
  • Operating temperature up to 300°C, with the possibility of reaching 400°C in special construction.
