Comefri - NPA-N

Heavy-Duty Airfoil Curved Plug Fans

COMEFRI heavy-duty centrifugal impellers NPA-N have been designed for clean or slightly dusty air, to achieve very high performances when not fitted within conventional fan housing.

The NPA-N impeller is manufactured in steel, with backward curved airfoil blades and painted finish.

Its special execution with a clever mix of narrow shape and high-tensile material allows an increase of speed up to 100 m/s which can develop (in the small sizes) a pressure greater than 4.000 Pa.

The application is very eclectic since it can replace DIDW fans in Air Handling Units with many downstream losses and achieve the final users with the full airflow.

It is ERP 2015 compliant.
