Air Flow Products PREGRILL2424 Lay-in Diffuser 24x24

Product Description

The AIR FLOW PRODUCTS PREGRILL2424 is a lay-in perforated grill diffuser designed for use in suspended ceiling T-bar grid systems. It fits a standard 24x24 inch ceiling grid opening and includes R6 insulation, making it suitable for both supply and return air applications in light commercial and residential HVAC systems. The perforated face panel distributes conditioned air evenly across the occupied space. This diffuser is installed by HVAC technicians and sheet metal contractors as part of a ducted forced-air system.

The PREGRILL2424 is intended for use in drop ceiling installations where a clean, flush-mounted air distribution solution is required. Its 24x24 inch format matches the most common suspended ceiling module size found in offices, retail spaces, schools, and light commercial buildings. The R6 insulation rating helps reduce thermal loss and condensation on the plenum-side of the diffuser, which is especially important in high-humidity environments or systems with large temperature differentials between supply air and ceiling plenum space.

Key Features

• Lay-in design fits standard 24x24 inch suspended T-bar ceiling grid without fasteners
• Perforated grill face provides even, low-velocity air distribution across the space below
• R6 insulation reduces thermal loss and limits condensation on the plenum side
• Suitable for supply or return air applications in ducted forced-air systems
• Flush-mount profile maintains a clean ceiling appearance in finished commercial interiors

Compatibility

Designed as an OEM-style lay-in replacement or new-installation diffuser for standard 24x24 inch suspended ceiling T-bar grid systems used in ducted HVAC applications.

Installation Notes

Installation is performed by a licensed HVAC technician or sheet metal contractor. Power to the air handling unit should be shut off at the disconnect before accessing the plenum or connecting ductwork to the diffuser boot. The diffuser simply lays into the existing T-bar grid opening and requires no additional fasteners in most standard grid configurations. Follow local mechanical codes and SMACNA guidelines for duct connection and sealing at the collar.
