Series ECG Egg Crate Grilles have an exceptionally high free area of 90%. This results in the ability to handle giant air volumes with minimal noise and pressure drop generation.
Although displaying incredible abilities when used for extract, Egg Crate Grilles incorporate no directional throw features and so are not recommended for supply applications. Series DD Double Deflection Grilles are of greater benefit in these situations. Egg Crate Grille core is also not designed to withstand impacts or pressure of any kind, and so should not be used in any area these dangers may be inflicted, like sports halls or near floor level in walkways.
Egg Crate Core is made from thin aluminium strips arranged into a lattice. The square holes in the core are sized 12.5mm x 12.5mm, resulting in a free area of over 90%.
This core is held within a one of two available frames. Designed to integrate with the wider range of HVC Grille frames, you can be sure of design consistency whatever grille you buy from HVC.
See the options tab above for more information on how we can adapt your Egg Crate Grille to suit your needs better. From integrating a grille into a burgess system, or adding volume control equipment to your grille to further enhance functionality.
