In the Unified Facilities Guide Specifications, Paragraph 2.12.4 states:
"Pressure drop in the damper open position shall not exceed 25 Pa 0.1 inch w.g. with average duct velocities of 13 meters per second 2500 fpm".

Are there manufacturer's who actually comply with the .1 inch w.g. requirement at 2500 fpm? The manufacturer's that I have checked, "Ruskin" and "Safeair", only comply at 2000 fpm.
Thanks for any assistance..
