LNG linear slot diffusers

(1)

M A D E L



The

LNG

series linear diffusers are designed to combine the aesthetics

with the technical performance.

They can be mounted in false ceilings or suspended from the ceiling.

They allow the formation of diffuser continuous lines, with active and

inactive areas, without breaking the uniformity of the whole.

They are suitable both for supply and return. By adjusting their blades it

is possible to obtain a horizontal distribution of the air in one or the other

direction or its vertical projection without change the volume of air.

The

LNG

diffusers admit a flow variation of 60 % keeping the air stream

stable.

(2)

LNG-AR

Diffuser with end borders included.

Suitable for lengths

_≤

2 m.

…-ARI

Diffuser with an end border on the left

side, required to form lines >2m.

…-ARD

Diffuser with an end border on the

right side, required to form lines >2m.

…-INT

Diffuser without end borders, required

to form lines > 4 m.
