The clean solution!

PURELINE slot diffuser

Unobtrusive

The PURELINE slot diffusers are neat devices that blend in perfectly with any ceiling.

Versatile
Adjustable air discharge – horizontal, angled or even vertical – makes the diffusers a versatile option for many applications, such as to provide an air curtain to protect fresh food counters.

Clean
As a big plus, there is less contamination of the ceiling with the PURELINE slot diffusers. This has been tested on a dedicated test rig of RWTH Aachen University, where a standard dust (ASHRAE) was used to compare the contamination caused by different types of diffusers. PURELINE came out as the cleanest slot diffuser by far.
