Air diffuser LDO-T

Product overview
The LDO-T overflow diffuser allows air to flow freely between two rooms and compensates for pressure differences while reducing transmission of noise and speech (cross-talk attenuation). It is designed for installation in partitions or glazed elements where pressure equalization and acoustic privacy are required.

Key features

• Quiet: high sound insulation with low pressure loss
• Visually versatile: front diffuser element can be powder-coated or painted in the RAL color of your choice
• Easy to install and maintain: front elements are easily removable for access and cleaning
• Safe: made from non-flammable materials
