SF Xtra Sound Attenuator Ventilator

Surface mounted ventilator
FOR USE ON VINYL, WOOD, ALUMINUM OR FIBERGLASS WINDOWS

Overview

The SF Xtra Sound Attenuator ventilator is a slot ventilator which provides high levels of sound attenuation compared to similar ‘acoustic’ products, in a compact size.

The SF Xtra Sound Attenuator 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 44dB when the vent is open and 55dB when closed.

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 and fits over the standard SFX, Trimvent SM, SW and Select or Select Xtra slot size.

  • ALUMINUM
