Spot cooling of transformers and generators and industrial equipment. Ventilation in warehouses, factories, foundries, laundries, garages, equipment rooms, and engines. Vane-axial fans tend to be the most efficient fans available for HVAC air-handling units—with efficiencies reaching up to 85%—largely because the direction of the airflow is little changed as it passes through the fan. including mounting legs , flexible connection as per standard details , fan housing for more details of axial fan of installation download this file .
