The Square Diffuser is offered in extruded aluminium construction that ensures long lasting usage. The Square Diffuser has removable core which simplifies installation and avoids visible mounting screws. The Square Diffuser allows 1, 2, 3 and 4 way air discharge as well as 2 way diagonal discharge. Extruded Aluminium Square Diffuser comes in four-way design and gives equal supply in all directions while three, two and one way diffusers limit the supply only in the required direction.
