Slot diffusers with adjustable slots

How many air slots do I need?

From the SLS line gratings with adjustable pattern sheets many variants are available. Each slot diffuser contains several slots, but how many slots do you need? The more slots in the slot diffuser, the greater the air capacity due to the diffuser. Furthermore, the height of the diffuser also varies as the number of slots increases. So you can also choose according to the height that fits in the room where the grille is placed:

Height 65mm   | Height 108mm

Height 151mmHeight 194mm

Height 237mm | Height 280mm


Furthermore, the air grilles are available in 14 different widths, varying between 300 and 1600mm. So you will always find a slot diffuser that fits!


Line grilles with adjustable pattern sheets in different mixed colours

In the case of Ventilationland, the adjustable slot diffusers are available in various mixed colours. Namely in RAL 9010, RAL 9003, RAL 9005, RAL 7001 and RAL 9016. There is no extra charge for these colours! This means that the slot diffuser always fits in the room where you place it or in the interior. Are you looking for adjustable slot diffusers in a different colour? We will be happy to make you an offer without any obligation.

Do you want more information about the different adjustable line grids or are you just looking for a custom solution?
