CD4 Ceiling Diffuser Face 450×450 / Nominal 350×350 w/o Damper

Series ECG egg crate grilles are the industry standard for extract grilles. Featuring a core with over 90% free area and vanes parallel to the airflow, these grilles can handle large air volumes while minimizing noise and pressure drop. They are ideal for areas requiring high air change rates, such as restaurant kitchens and painting booths.

For applications requiring sight blocking and angled airflow, a 45° core is available. Additional options include removable or hinged cores for easy maintenance.

We stock large quantities of popular ECG sizes, enabling us to fulfill even the largest orders for next-day delivery. Non-standard sizes are manufactured to order.
