Diffusers & Grilles

Holyoake’s Diffuser and Grille Selection Programme is your online tool for selecting the appropriate diffuser or grille for various applications based on parameters like construction and performance. It includes product and performance information that you can download to assist in your selection.

New Features:

• Selection List - create a list of all the products on a project by clicking the "+" symbol button on one or more diffuser models.
• PDF Reports - generate a report for a specific product by clicking the "Create PDF" button under the diffuser model.
• Comparisons - compare the performance change between variations by clicking the "Compare" button under the diffuser model.

Data is based on available component manual data. Other sizes are available, please contact your local Holyoake Branch.

Performance data is only accurate up to the maximum listed airflow for each size as stated in the component manual. Please ensure that the size and airflow you have entered is suitable for the application. If in doubt, please contact your local Holyoake Branch.
