WebThe Adjustable Pressure Controller (APC) provides mechanical adjustment of start open pressure for the Greenheck model EM series damper. The APC is mounted to the bottom frame member (sill) and connects to the bottom blade linkage pin. Dampers MUST be equipped with blade counterbalance. WebWhen installed, this control system will automatically vary the speed of a booster fan to maintain a constant pressure within the system. A Greenheck exhaust fan with a Vari-Green motor is required for use with the controls and must be ordered separately. Parts List - provided by Greenheck Pressure Tap Pressure Transducer Control Box
