Fan Filter Units - Testing Setup

Principles - Laboratory testing to obtain multiple accurate measurements under various operating conditions.

Device Layout - The FFU to be tested will be mounted horizontally or vertically on the exit of the air chamber.

Control and Methods - Use an ancillary fan and a damper to control the airflow rate across the FFU tested.

Instrumentation - Unit airflow rate, total power usage, and static (and total) pressure across the FFU.
 

MEASUREMENT STANDARD: We have developed a draft standard to allow uniform evaluation and comparison of fan filter units. Send comments to Tim Xu.
