What Is an Egg Crate Grille? Specs and How to Specify One
An egg crate grille uses an open square-cell grid for high free area airflow, most often on return and exhaust air openings. Specs, applications, and how to specify one.
An egg crate grille is an HVAC air terminal built from a grid of small square cells, giving it a high free area compared to bladed grille types. Goodwind manufactures the Egg Crate Grille (model ECG-D001) in aluminum, steel, or custom material, for commercial, residential, and industrial projects.

Where Egg Crate Grilles Are Used
The open grid design gives an egg crate grille more free area than a bladed grille of the same face size, so it passes more air for less pressure drop. That makes it a common choice for return air and exhaust openings, where directing the airflow in a specific pattern matters less than moving volume efficiently. It's less suited to supply air positions where a defined throw pattern is needed.
How to Specify an Egg Crate Grille
For MEP Consultants at the Design Stage
Specify egg crate where the opening is on the return or exhaust side and free area is the priority. If the position needs directional throw control for supply air, a bladed grille or diffuser is the better fit instead.
For Contractors at Procurement Stage
Confirm the mounting method (wall, ceiling, duct, or floor) and finish against the drawing before ordering, since the grille is manufactured to the specified size rather than stocked in fixed dimensions.
