Linear slot diffusers needed a rectangularshaped plenum box with the opposed-blade damper for airflow Regulate. The plenum box includes a round duct collar for a flexible duct relationship. It is essential which the duct collar around the plenum box of linear slot diffusers is place around the side of the plenum box as an alternative to on the highest.

Directional and round diffusers don’t provide air vertically. In the meantime, linear slot diffusers don’t supply air horizontally.

Should you have ceilings that has a top of 12 meters, you may control the availability airflow based upon the diffuser datasheet to cap the air toss at all-around nine meters so that you don’t blast chilly air on individuals’s head however you allow the air to vacation close more than enough to the ground and Allow it sink Obviously. Thus, you don’t waste energy.
