Blower Performance Data
For wet coil performance fi rst calculate the face velocity of the air coil (Face Velocity [fpm] = Airfl ow [cfm] / Face
Area [sq ft]). Then for velocities of 200 fpm reduce the static capability by 0.03 in. wg, 300 fpm by 0.08 in. wg, 400
fpm by 0.12in. wg. and 500 fpm by 0.16 in. wg.
