Kelair Inlet Vane Dampers available at Duncan Co

Inlet vane dampers are used for applications that require a reduction of expanded power and wear on heavy duty fans. Our inlet vanes pre-spin the air in the direction the fan blades are moving thus reducing energy consumption by the fan motors. Kelair’s unique central gearbox eliminates the damage prone external linkage of traditional inlet vane designs. Kelair offers dampers that are built specifically for each order and typically ship within 3-4 weeks depending on the actuator lead times.
