Egg Crate Grille (Removable Core)

Product Overview

CVE Shop Egg-crate Grilles have an exceptionally high free area of 90% which is why Egg-crates are considered to be the industry standard grille for exhaust and air transfer applications. A high free area results in the ability to handle giant air volumes with minimal noise and pressure drop generation. The 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.

CVEGRC-150 150mm x 150mm (W x H)
