Pressure Tracking
The Variable Frequency Drive (VFD) inside the control panel allows the unit to track the usage of the
filters. This allows the unit to automatically increase the speed of the motor to compensate for the
additional air restrictions caused from dirty filters. This feature is an automatic feature and cannot be
disabled. This feature alone can save up to 50% of the energy costs over the life of the filters.
Reduced Maintenance
The Variable Frequency Drive (VFD) manages the motor's operating speed. This in turn controls the
airflow inside the unit and allows for more efficient operation through the Pressure Tracking feature.
This reduces the impaction of dust upon the filters inside the unit and allows. The reduced impaction
means the dust can be cleaned easier and every cleaning cycle is more efficient. This feature can
increase the life of the filter by up to 100% which reduces maintenance time and costs.
Reduced Noise
Noise is created inside a unit by moving parts such as the blower wheel and moving fluids such as
the air through the unit. With the VFD, the air flow is managed through the blower control. By
managing the airflow, the noise due to moving parts and moving air is reduced.
