Acoustic Air Transfer Unit KATCONTENTS Acoustic Air Transfer Unit 2

Acoustic Air Transfer Unit - KAT Description The KAT sound attenuation air transfer unit offers a high sound absorption level, low pressure loss, easy installation and attractive design. Air is moved to adjacent rooms by the transfer unit by the pressure difference between the rooms. The low pressure loss of the device allows large air volumes to be moved between areas. The unique design allows the unit to be installed in plasterboard walls for air movement between adjacent areas, while also avoiding vision through the device and ensuring room-to-room sound reduction to guarantee conversation...

A = KAT-T 500 B = KAT-Z 500 C = KAT-T 1000 D = KAT-Z 1000 The listed values for the KAT correspond to transfer units with a front component and sound levels below 35 dB(A) for the flow rates listed in the chart. With front element The sound attenuation of the unit is calculated by the Nordtest NT Acou 037 method. The total wall attenuation in each frequency band is calculated using the following formula: Rp = total wall attenuation in the frequency band considered (dB) S = wall area, in m2 R = wall attenuation in the frequency band considered, without transfer unit (dB) D1 = attenuation of transfer...

Technical data Acoustic data To reduce sound transmission from one room to an adjacent room to an acceptable level, the sound attenuation component used to move air is lined with a sound-absorbing material. The resulting sound data on airborne noise (R) reduction are given by the sound reduction index and the difference in standard sound level. The airborne noise (R) reduction is defined as follows: The difference in standard sound level is given by the equation: D = L1— L, + 10-log( A0 n, e 12 A To calculate the weighted sound reduction index RW in the wall of a room, the dimensions and...
