Rectangular Duct Silencer 800 x 500 x 1000 mm

A broad acoustic section for large supply or return trunks.

A large front section suits central ventilation routes.
Bolted end flanges allow the attenuator to form part of a serviceable duct assembly.

Введение продукции

The large rectangular casing accommodates a substantial internal absorber arrangement. Its taller and wider face serves trunk-duct routes near central plant, where noise treatment must be integrated without reducing the nominal duct opening.
