The Ventuer AB-55 is a solid acoustic screening system designed to reduce airborne noise transmission and provide sound absorption on the exposed face. Constructed from aluminium sheet with a sound-absorbent core and stainless steel internal mesh liner, it delivers a strong, corrosion-resistant and washable solution suitable for both internal and external applications. With a slimmer profile, the AB-55 balances acoustic performance with space efficiency. The system achieves an STC rating of 33 and an NRC of 1.05.
