AXIAL FLOW FANS PERFORMANCE DATA
Selecting from these graphs provides a guide only to possible selections. Basic noise level data as well as indicative power
absorbed figures are incorporated on the graphs. The Fans by Fantech Product Selection Program will show other possible impeller
combinations between the two illustrated here for each fan size/speed. The Selection Program will provide full performance
information including air flow, pressure, noise levels, absorbed power as well as complete dimensional information.
