Series RIF-SD

Ventilators in the Series RIF with sound absorbing extras are perfect for applications with high noise reduction requirements.

The ventilator shaft is lined with non-combustible sound absorbing slabs that have an abrasion-proof glass fibre surface. The sound attenuated gravity roof ventilators have been tested by a neutral institute in the echo chamber and in large-scale tests.

Series RIF-SD gravity roof ventilators can attain a sound insulation factor R'w of up to 35 dB and they are designed to meet acoustic specifications on a project-specific basis.
