Centrifugal Fans
Centrifugal fans for duties that must overcome coils, filters and long duct runs: AHU / RTU, data-center CRAH, dust extraction and process ventilation. The LONGWELL centrifugal platform covers backward curved, forward curved and plug-fan (RLM) constructions on AC / DC / EC motors. Final selection is confirmed at the duty point (airflow / static pressure / voltage / control mode) and by project verification.
