EDLS - EDLSB Linear Diffuser for Hidden Installation
Description
Hidden linear diffuser with single 20 mm or 30 mm slot with aerodynamic aluminum profile and adjustable deflectors for optimal air throw control. Also available with sliding volume damper.
Features
Material: aluminium.
EDLS finish: black RAL9005 painted aluminum frame and deflectors.
EDLSB finish: white RAL9016 painted aluminum frame and deflectors.
Slot: 20 mm or 30 mm.
Installation: by plenum box with mounting bridge, ceiling finishing with anti-crack tape on the frame and subsequent plaster skimming.
Possible dimensions in one piece:
- minimum length 300 mm;
- maximum length 2000 mm.
Use
Diffuser suitable for both air supply and exhaust in large rooms. Its modularity allows great freedom of design.

Diffuser dimensional details
Operating data
Data referring to 1m long diffusers, with a terminal throw velocity Vt=0.25 m/s and with a temperature differential of 10/12°C, in ceiling installations and with lateral air throw.
Data referring to diffusers without damper or with open sliding damper.
Data referring to diffusers with deflectors in the working position with a 50% reduction of the air passage surface.
The position of the deflectors reduces the effective cross-section. When the deflectors are fully open or when the diffuser is used for air exhaust, the flow rates expressed in m³/h indicated in the table may be higher.
Vk: effective speed (m/s)
m³/h: air flow rate
Pa: pressure drops in Pascal
L(m): air throw in metres
dB(A): noise level

Continuity kit
The continuity kit is an accessory required to create continuous lines of linear diffusers longer than 2 metres. It is made up of two junction plates that allow for the alignment and connection of two components of the line.
