  • New filter... Pressure drop comparison data

    22/8/2008  In an effort to get my static pressure down several filters have been tested for pressure drop. I have learned so much from this site I figured I would give something back and share the data.... The blower is set on 400CFM/ton (1600 CFM) but is likely delivering only 1400 CFM at my high static pressure according to the servicts facts section in the installation manual.
