Air Flow Products AVDF4N60 Lay-in Ceiling Diffuser 24x24

Product Description

The AIR FLOW PRODUCTS AVDF4N60 is a lay-in ceiling diffuser designed for use in suspended T-bar ceiling grid systems. It features a four-cone diffuser face that distributes conditioned air in a 360-degree horizontal pattern, promoting even air distribution across the occupied space below. The unit ships without a collar, making it suited for installations where the connecting ductwork and plenum box are sourced separately. R6 fiberglass insulation is integrated into the body to reduce thermal loss and limit condensation on the diffuser casing in cooling applications. HVAC technicians and commercial sheet metal installers are the primary trades for this type of unit.

This diffuser is intended for commercial and light commercial HVAC applications where a standard 24x24 inch lay-in ceiling tile footprint is required. It drops directly into a 24x24 inch T-bar grid opening. The four-cone face style is commonly specified in offices, retail spaces, classrooms, and similar occupied environments where uniform air distribution and a clean ceiling appearance are priorities. The no-collar configuration requires field connection to the supply air plenum or flex duct above the ceiling plane during installation.

Key Features

• Four-cone diffuser face delivers 360-degree horizontal air distribution pattern
• Fits standard 24x24 inch T-bar suspended ceiling grid openings
• R6 fiberglass insulation reduces thermal bridging and condensation on the diffuser body
• No-collar design allows flexible field connection to plenum or flex duct
• Lay-in installation requires no fasteners into the ceiling grid

Compatibility

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

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Shut off the air handling unit and confirm zero airflow before positioning the diffuser in the ceiling grid. The no-collar opening must be connected to a properly sized plenum box or flex duct collar above the grid before the unit is set in place. Verify that the ceiling grid is rated to support the weight of the insulated diffuser assembly prior to laying it in.
