Daniel, The key item which you should have is an anemometer probe. They are available at reasonable prices. This will allow you to measure airflow at the power supply under test. A simple box (length several times width and height to linearize flow) with fans mounted at the outlet end will be all that is needed, plus a variable supply to throttle back the fans until the correct LFM is measured. You will need a couple of holes in the side of the box for probe access. Keep the holes small - most "hot wire" type probes are less than half an inch in diameter. CFM (fans required) = LFM X Cross-sectional Area of box. Have Fun Scott
ORIGINAL MESSAGE "My company produces AC to DC Power Supplies. I have been directed to make a quick and dirty test rig that will allow me to put a predetermined airflow in LFM over the unit. Does anyone know of a website that describes something like this or have had experience building such a test rig and would be willing to share their expertise." Daniel W.
