Slot Diffuser

Type LS20

LS20 is a multi slot diffuser suited to short or long runs and both internal and external mitres, at any angle can be achieved. Due to its construction, straight lines are not a problem and its use as a ceiling support system is well-proved.

Non-active sections can be used for return application and the injected nylon pattern blades can be set for horizontal or vertical throw.
