Sound attenuator PK is a high-performance silencer designed for HVAC systems, offering excellent noise reduction across a wide frequency range from 63 Hz to 8000 Hz. The attenuator is built with non-flammable, Class A1 rock wool and complies with international standards (VDI 6022, DIN 4102/T17, DIN 1946, and VDI 3803). Sound attenuator PK is engineered for durability, performance, and compliance with hygiene and fire safety standards, making it a reliable choice for commercial and industrial ventilation applications.

Its aerodynamic splitter design ensures minimal pressure loss, making it ideal for systems with high airflow velocities.
