Noise attenuators — ADR splitters
The problem
The plant room is sound-insulated, but it needs ventilation. Ventilation is the hole through which everything gained with the envelope escapes.
The solution
Splitter-type attenuators designed for high noise reduction with low back pressure, in systems that require airflow. Their performance covers a wide band from 63 Hz to 8 kHz.
Specifications
| Transmission loss | Up to 50 dB in the most demanding designs |
|---|---|
| Frequency band | 63 Hz – 8 kHz |
| Minimum area | 600 × 600 mm |
| Maximum area | 2400 × 2400 mm |
| Lengths | 600, 1200, 1500, 1800, 2100 and 2400 mm |
| Finish | Galvanised steel or electrostatic paint |
Applications
HVAC ventilation ducts and exhaust stacks, gas turbines and power plants, genset air intake and exhaust, plant room and industrial building ventilation, axial and centrifugal fans.
Which requirement does it help you meet?
Low back pressure is not a sales detail: if the attenuator chokes the flow, the equipment loses performance or shuts down. Correct sizing requires knowing both the acoustic requirement and the pressure drop the element can add to the system. These products are also commonly needed to comply with D.S. No. 38/11 MMA.
