Air Flow Products ERIF0024 Insulated Return Grille 24x24

Product Description

The AIR FLOW PRODUCTS ERIF0024 is an insulated egg crate filter return grille sized at 24x24 inches. It is designed to house a filter media in a return air application, drawing conditioned-space air back to the air handler or furnace while blocking particulates at the face. The insulated construction reduces condensation on the grille surface in humid environments, making it well suited for residential and light commercial HVAC systems. HVAC technicians and mechanical contractors install this grille as part of a ducted forced-air system wherever a filtered return opening is required.

This grille is used at return air openings in ceilings, walls, or floors of residential homes, apartment units, and light commercial spaces. The egg crate face pattern provides low air resistance across the full 24x24 inch opening while the integrated filter slot keeps replacement filter access straightforward. It is a common choice in applications where condensation control at the grille face is a service or comfort concern, particularly in high-humidity climates or in unconditioned spaces adjacent to conditioned zones.

Key Features

• Insulated construction reduces surface condensation in humid environments
• Egg crate face pattern provides low static pressure drop across the return opening
• Integrated filter slot allows filter media to be held at the grille face
• 24x24 inch nominal size fits standard return air rough openings of the same dimension
• Suitable for ceiling, sidewall, or floor return air installations

Compatibility

Designed as an OEM-style replacement or new-installation return grille for ducted forced-air HVAC systems requiring a 24x24 inch insulated filter return grille at the return air opening.

Installation Notes

Installation is typically performed by a licensed HVAC technician or mechanical contractor. Shut down the air handling system at the thermostat and disconnect power at the disconnect or breaker before removing an existing grille or cutting a new opening. Verify the rough opening dimensions match the grille size before securing to the wall, ceiling, or floor surface. Follow local mechanical codes and manufacturer fastener recommendations when mounting.
