Specialized equipment such as anemometers is used to accurately measure the air velocity and calculate the airflow rate. The static pressure of the fan, which is its ability to push air against resistance, is also tested using manometers.

Speed accuracy is another important parameter. DC motor blower fans are often required to operate at specific speeds, and any deviation from the set speed can affect the performance of the overall system. Therefore, the speed of the fan is carefully measured and adjusted during the testing process. Power consumption is also monitored to ensure that the fan meets the energy efficiency requirements.

Reliability testing is equally important. Fans are subjected to accelerated life tests, where they are run continuously for an extended period under various operating conditions to simulate real world usage. This helps to identify any potential issues with the motor, bearings, or other components. Environmental testing is also carried out to ensure that the fans can withstand different environmental conditions. For example, fans may be tested for their ability to operate in high temperature environments (up to 85°C or even higher in some industrial applications), low temperature environments (down to 40°C in automotive or outdoor applications), high humidity conditions, and environments with high levels of dust or vibration.
