Air Grilles

With the spiraling costs of electricity and the push for being as environmentally friendly as possible, businesses such as datahalls and large offices require ways to minimize these aspects while still maintaining (or increasing) the current airflow and cooling systems. Air grilles/air panels are the solution. By allowing for the flow of air in any specific direction or by limiting/increasing the flow of air, Air Grilles increase the efficiency and effect of airflow. This allows businesses to use less electricity to obtain the same, and often better, results.

There are different types of Air Panels available depending on the situation and result required. ACRA have found the most commonly utilized Air Grilles for our customers are the panels with Free Flow (FQ) factors of 16-24%, 32%, 40% and 65%.

ACRA currently offer the following hole patterns:
