Non-Ducted Return Hood Released

METALAIRE is pleased to announce the release of the Model NDRH Non-Ducted Return Hood. The Model NDRH is designed to reduce the amount of sound transmitted from or into the plenum space through return grilles in non-ducted applications.

NDRH_office_PhotoSound transmission from office to office or mechanical noises from the plenum of non-ducted returns can be an ongoing nuisance issue. The Model NDRH significantly reduces the amount of sound transmitted into or from the plenum and also functions effectively as a light shield. It can be used with any of METALAIRE's T-bar lay-in return grilles (RH, CC5, 7500R, etc.) specifically for use in non-ducted return applications.
