designs and fabricates test facilities for customer testing
programs in a wide range of flow capacities for fan performance
characterization and other applications requiring accurate
mass flow and static pressure measurements. Single and multiple
nozzle Outlet Chamber Setups (Figure 01 and Figure 02) are
most common. These units may be ordered with classical measuring
instruments or fitted with transducers that provide digital
output enabling full or semi-automated testing programs. The
AMCA 210-85
/ ASHRAE
51-1985 Standard, Laboratory Methods of Testing Fans
for Rating, presents detailed design parameters and
testing methods for evaluating axial and centrifugal fans.
