Greenheck 468292 Adjustable Pressure Controller is designed to provide mechanical adjustment of start open pressure for Greenheck model EM series dampers. It mounts to the bottom frame member and connects to the bottom blade linkage pin. The APC is capable of resisting damper opening pressure up to 0.75 in. wg (187 Pa) for a 4 ft² (0.37 m²) area, and 0.125 in. wg (31 Pa) for a 24 ft² (2.23 m²) area. It helps to ensure proper airflow and prevents backdrafting by adjusting the pressure required to open the damper blades.
