HLO-1021 | Accessory: Crankarm; Damper Blade, 6″

The HLO-1021 damper blade crankarm is a replacement part for a component of an HLO-1050 linkage kit. An HLO-1050 linkage kit is installed for an AFMS (Airflow Measurement System) on units with vertical-axis damper blades. The linkages transfer the damper motion to a surface with a horizontal axis, on which the AFMS controller’s inclinometer can then be mounted.
