Application

Floor fixed bar aluminum grilles AR-8, AR-9 are used for air supply and exhaust in all kinds of low pressure air

handling.

Description Floor fixed bar aluminum grilles AR-8, AR-9 are made of cold-worked sectional aluminum, galvanized in natural

aluminum colour, fixed vertical vanes are designed so as to achieve the horizontal air injection at AR-8 and in theO15 angle air injection at AR-9. Both are intended for floor installation. The attached accessory devices for air flow

rate and direction control are made of black varnished pickled sheet.

AR-8, AR-9

The supply and exhaust air grilles AR-8, AR-9 consist of supporting frames and vertical fixed bars.

Effective intakeArea F (m2)efAR-8, AR-9

The intake air flow is determined by measuring the intake air velocity

at parallel set-up bars. The intake air flow can be calculated as

follows:

Q = V x F x 3600ef ef

For the grilles the following values are required:

1. Normal rooms V’ = V

2. Rooms with explicitly reverberating walls V’ = 0.5V

3. Rooms with absorption walls V’ = 2V

The following tables include the results of tests conducted on three single deflection linear grilles. The

test results include Noise Criteria (NC). Static pressure versus air flow, throw and Ak. The grilles were

selected and supplied by Beta In August 1994. The Extrapolations and interpolations were made to Cover

a range of sizes and parameters according to the ETL testing laboratories Inc. who conducted the tests.

The linear grilles Were tested in accordance with the Air Diffusion Council test code for

grilles registers and diffusers No. ADC 1062: GRD-84. The grilles were tested in the ETL

testing laboratories.2The 470m reverberation room was used to conduct the tests. Quiet test air was provided' by a variable

volume air supply. Air volume was measured by the use of calibrated Orifice metering station while the

static pressure was measured employing a Dwyer Model 166-12,1/8’ diameter standard pitot tube and

read on a dwyer manometer Model 424-5.

Acoustical data was obtained Employing a Bruel and Kjaer digital frequency analyzer type 2131 and

analyzed on a computer. The reference sound source for this test was a calibrate ILG Fan Serial No. 17-

05-066A. The Octave band sound power levels were plotted on a graph of noise criteria curves which

is in the ADC test! codes.
