The ASX Pressure control system uses the flexibility of our highly efficient EC motors and controllers in
conjunction with accurate pressure measuring equipment and a versatile setpoint control unit to maintain a
user-defined duct static pressure.
The system consists of the following three components:
NOTE:
Fan must be sized appropriately for the system it is connected to as well as all intended system
configurations.
NOTE:
The ACU can be used to manually control the output of the motor independently from the rest of the
pressure control system. This is beneficial for system balancing as well as for fine tuning of the setpoint
control system. Refer to the ASX ECM - ACU Control Specification Sheet for details on how to operate
the ACU controller.
