NOTES: NOTES:

The air diffusers were tested in accordance with the Air diffusion council test code for grilles, registers and diffusers n o. ADC

1062.GRD.84, the test was conducted in ETL testing laboratories.

The diffusers were installed in the ADC facility and supplied with measured volume of air. The static pressure was measured

(1-1.5) duct diameters upstream of the diffuser inlet.

Acoustical data was obtained employing Bruel and Kjaer digital frequency analyzer, and analyzed by computer. Sound power

levels were plotted on a graph of noise criteria curves which are in the ADC codes.

PERFORMANCE DATA

The following tables include the results of tests conducted on three linear slot diffusers. The test results include Noise Criteria

(NC), static pressure versus air flow, throw and Ak. The diffusers were selected and supplied by Beta In October 1991. The

extrapolations and interpolation were made to cover a full range of sizes and parameters according to ETL testing laborato-

ries Inc. who made the tests.
