Inaudible Flow Rates - Side Round Diffusers
The flow rates provided below ensure a remarkably low noise level of 17 dB(A).
- Installer Standards: While many installers consider 25 dB(A) to be the level of inaudible noise, we deliberately use a lower figure (17 dB(A)).
- Safety Margin: This conservative lower figure allows for common upstream constrictions, such as dampers and other fixings, ensuring truly silent operation in your space, even under less-than-ideal conditions.
