Air Feed Hoods
Blocks noise that passes through air vents.
Molded Acoustical Products’ air feed hoods are formed of fiberglass air outlets for use in standard 24″ x 24″ ceiling grid systems. MAP’s air feed hoods are constructed with foil barrier backing that reduces condensation while providing optimum thermal and acoustic properties. Designed for field installation, the face of the feed hood includes a cut layout set for a circular 360-degree duct pattern.
