Air Diffuser Combination Type LDK-B for Wall Installation Selection The damper installed in the connection cross section serves to fine tune and set varying flow rates with identical duct pressure. - substitute the frequency- dependent insertion attenuation of diffuser and cross- talk damper (substitute twice!) More significant pressure variations along the air ducts may only be compensated to a limited extent. - convert to sound pressure of the receiving room after deducting the room absorption (frequency- dependent if available) Duct connections should be smooth and efficiently flowed into...
