NDRH - Non-Ducted Return Hood

The Model NDRH is a non-ducted return hood designed for field installation as an accessory to return grilles in non-ducted plenum HVAC systems. This product is particularly beneficial in applications where noise reduction and light blockage are desired. It seamlessly integrates with a variety of METALAIRE T-bar lay-in return grilles, including RH, CC5, and 7500R models, making it a versatile choice for optimizing air distribution in commercial and residential spaces.

Crafted from durable 22 gauge galvanized steel, the Model NDRH features a robust construction built to withstand the rigors of HVAC systems. Its interior is lined with 1/2" fiber insulation on three sides, effectively reducing sound transmission by 7-10 NC. This sound-dampening feature contributes to a quieter and more comfortable environment by minimizing noise transfer through the return air path.

The Model NDRH is an ideal solution for a range of construction projects, including offices, retail spaces, and educational institutions, where a non-ducted plenum approach is employed. Its compatibility with T-bar ceilings and ease of installation make it a practical choice for both new construction and retrofit applications. By mitigating noise and preventing light infiltration, the Model NDRH ensures optimal performance and a more aesthetically pleasing finished appearance.
