Product Description

CRF grain drying diagonal flow fan combines features of axial and centrifugal fans, optimized for heat distribution, dust separation, and debris handling in grain drying. Featuring a cylindrical casing with at wo-stage flanged conical intake collector and outlet stationary guide vanes, it axially draws airflow, redirects and pressurizes it via impeller expansion and static vane compression, then discharges axially.Delivering higher pressure than axial fans and greater airflow than centrifugals, it offers high efficiency, low noise, compact design, and easy installation with uniform airflow distribution and stable pressure performance.

SCOPE OF APPLICATION
It is suitable for drying grains and other agricultural and sideline products, and can also be used for ventilation in industrial and mining enterprises,public facilities and high-rise buildings.
