LARGO T4
The sound attenuator is supplied insulated with 50 mm thick fire-resistant stone wool.
- In many applications, sound attenuators are installed in fire-resistant insulated duct systems. In applications in which ventilation ducts are to be insulated with 50 mm thick fire-resistant stone wool, you can either install external insulation over the sound attenuator directly at the building site or place an order for the factory-insulated variant.
- For the LARGO, the factory-insulated variant is available as an accessory. You can choose to insulate the cleaning cover only (LARGO T2) or insulate the whole sound attenuator (LARGO T3).
- The acoustic data and pressure drop do not change if the LARGO T2 accessory or the LARGO T3 accessory is used.
