SF Xtra Sound Attenuator (Acoustic) Vent
Overview
The SF Xtra Sound Attenuator ventilator is an acoustic slot ventilator which provides high levels of sound attenuation compared to similar ‘acoustic’ products, in a compact size.
The SF Xtra Sound Attenuator vent can be purchased in a number of combinations based on different sizes of inner (ventilator) and outer (canopy). Combinations can be chosen depending on the sound attenuation requirement and can achieve up to Dn,e,w (C;Ctr) = 44 (-2;-3)dB when the vent is open.
The product is a cost effective method of reducing incoming noise in situations where conventional slot ventilators are unable to assist with acoustic issues.
The SF Xtra Sound Attenuator comes fitted with a Titon SF Xtra Ventilator and/or SF Canopy (HF Canopy for 5000EA version) and fits the 2500mm2 EA version over the Trimvent Select, Trimvent 4000 Hi Lift or Select Xtra slot size.
Suitable for
- PVCu
