This document deals with the likely degradation of air performance of fans tested in standardized
airways in accordance with ISO 5801 when compared with the performance of fans tested under actual
site conditions. It deals with the performance of a number of generic types of fan and fittings. The
results given are intended as guidelines and only provide trends, as the system effect depends on the
exact geometry of the fan and disturbing component.
The test data presented in this document are taken from an extensive experimental program conducted
20 years ago by NEL (National Engineering Laboratory, UK), mainly on axial and centrifugal fans.
Data are also taken from several research projects financially supported by ASHRAE, some of them
being carried out in the AMCA laboratory in Chicago, as well as from results published previously by
individual fan manufacturers.
