Forward Curved Centrifugal Fans
Forward curved (multi-vane) impellers move more air at the same outer diameter in a compact envelope, ideal for space-constrained equipment integration; available single inlet with housing, dual inlet and free-running. Final selection is confirmed at the duty point (airflow / static pressure / voltage / control mode) and by project verification.
