Ceiling diffusers Α1 ÷ Α4 have fixed blades configured for air supply into 1 ÷ 4 directions. They are suitable for air supply in air-conditioning and ventilation systems and ceiling or air duct installation.

Ceiling diffusers Α1 ÷ Α4 can be manufactured from anodized aluminium or aluminium painted in RAL color :
Α1 ÷ Α4... : Blades & frame from anodized aluminium or aluminium painted in RAL color.

They can be installed in spaces with height up to 4 m and they are ideal for systems with variable flow rate as the configuration of the blades achieves steady stream morphology at high velocities, eliminating the risk of flow detachment from the ceiling in case of low air supply. The ability to achieve airflow with high velocities makes the grilles A1 ÷ A4 suitable for installation in spaces with large temperature difference between the air within the space and the supplied air.
