Hart & Cooley 50354 – 2' x 2' Perforated T-Bar Diffuser with Insulated Backpan

The Hart & Cooley 50354 is a 24" x 24" lay-in T-Bar diffuser engineered for effective supply air distribution in commercial HVAC systems. It features a perforated steel face with a fiberglass-insulated backpan, making it suitable for standard suspended ceiling grid installations where air diffusion, durability, and ease of integration are critical.

Product Highlights

• Perforated Steel Face – Facilitates uniform air discharge across the ceiling space, reducing drafts and promoting consistent air mixing.
• Factory-Attached Fiberglass Insulation – Molded R4.2 fiberglass insulation reduces thermal loss and condensation, maintaining HVAC system efficiency.
• Snap-In Collar Compatibility – Accommodates 6" to 16" snap-in collars for flexible duct connections and quick configuration in field installations.
• Standard 2' x 2' Ceiling Fit – Designed to lay into a typical T-Bar ceiling grid with no additional modification required.
• Powder-Coated Finish – Bright white enamel coating provides a clean aesthetic and resists corrosion in controlled environments.
