Air diffuser LW module 12clean/2

Overview
Wide range of variants for wall installation in HVAC systems, combining an attractive appearance with efficient air distribution. Designed to meet individual project requirements and to integrate into various wall build-ups.

Key benefits

• Effective: ensures clean, fresh air distribution with optimised ventilation effect
• Whisper-quiet: high cross‑talk sound attenuation thanks to the integrated silencer
• Flexible: variable box shapes for different wall installation situations — easy to install and maintain
• Customizable: tangential or mixed-source ventilation selectable according to requirements
• Easy to clean: minimal soiling around the diffuser due to the patented LTG System clean®

Technical data

• Number of slot rows: 2
• LTG System clean®: Standard
• Supply and exhaust air volume at LWA = 35 dB(A) [m³/h at L = 1000 mm]: 75
• Integrated silencer: Standard (increases cross‑talk sound attenuation)

Dimensions (length in mm)

• Available standard lengths: 800, 900, 1000 and 1200 mm — other lengths on request
