Ventilation system is the path through which air is pushed or pulled. Since it can be any combination of ducts, heat exchangers, filters, etc., through which air flows, a system can range in complexity. The system can be as simple as exhausting air through an opening in the wall of a building, or as involved as a multi-zoned system with varying flows and densities. The effects of the system design on the actual performance capability of a fan represent separate and equally important considerations.

Fans are typically tested and rated in prescribed test configurations defined by the Air Movement and Control Association. This is done to ensure standardized procedures and ratings so that system designers can make realistic choices among various manufacturers. Beyond the routine system resistance calculations, the location of some common components and their proximity to he fan inlet or outlet can create additional immeasurable losses commonly called System Efect. These losses, if not eliminated or minimized, will necessitate fan speed and horsepower increases to compensate for the performance deficiencies.

In the typical process of system design, the performance requirements are calculated and then used to select the appropriate fan. However, in many cases the effects of the relationship between the system components and the fan are not considered in the calculation or selection process. For instance, the resistance of a given size elbow at a given flow can be easily determined using the equivalent length calculation method. However, if that elbow is located at the fan inlet or outlet, further immeasurable losses will be imposed in addition to the simple loss through the elbow itself. Most importantly, these losses cannot be measured or even detected with field instruments because they are, in fact, a destruction of the fan performance characteristics. Standardized testing and rating methods for fans have been established by the Air Movement and Control Association, (AMCA). The test methods are described in AMCA Standard 210, titled Test Code for Air Moving Devices. Specifying fan equipment tested and rated in strict accordance with AMCA Standard 210 is the best way to ensure accurate fan performance. However, the system effects that alter or limit the ultimate performance remain the most frequent causes of field performance problems. The four most common causes of system-induced performance deficiencies:

- Eccentric flow into the fan inlet.
- Spinning flow into the fan inlet.
- Improper ductwork at the fan outlet.
- Obstructions at the fan inlet or outlet.

Fans perform correctly when air flows straight into the inlet. Air should be drawn into the fan inlet with an evenly distributed velocity profile. If the air is not drawn into the fan inlet evenly, performance deficiencies will result from the combined effects of turbulence and uneven air distribution. When the system attempts to change the direction of flow, the air hugs the outside of the inlet elbow entering the fan. This causes uneven, turbulent airflow into the fan.
