PRTB / SPRTB - Perforated Screen for Non-Ducted Plenum Return

The PRTB and SPRTB series offer a cost-effective solution for non-ducted plenum return air applications in commercial and residential HVAC systems. These perforated screens facilitate efficient air circulation while eliminating the need for traditional ductwork, simplifying installation and reducing material costs. PRTB models are constructed from corrosion-resistant aluminum, while SPRTB models feature durable steel construction, providing options to suit various environmental requirements and project specifications.

Both PRTB and SPRTB screens arrive ready for installation without pattern controllers, allowing for straightforward integration into existing ceiling grids. A key feature of these products is the optional T-bar plaster frame (TBPF) accessory, enabling seamless surface mounting applications for enhanced design flexibility. Available in a range of sizes compatible with common T-bar ceiling systems, including 6" lay-in, 8" tegular, and 9" Donn Fineline configurations, these versatile screens cater to diverse project needs.

The PRTB/SPRTB series finds wide application in commercial buildings, offices, retail spaces, and institutional settings where non-ducted return air systems are preferred. Their discreet design blends seamlessly into standard ceiling grids, maintaining a clean and unobtrusive aesthetic without compromising ventilation performance. Furthermore, the availability of various finishes, including white, satin silver, black, and custom color options, allows these screens to complement a wide range of interior design schemes.
