SONOFLEX is an acoustic flexible duct designed for ventilation and air conditioning systems requiring excellent sound attenuation. Its multi-layer structure with perforated Alutex inner core and 25mm glass wool insulation delivers superior acoustic performance.

With M1 fire resistance and temperature tolerance from -30°C to +140°C, this duct ensures safety and durability in HVAC installations. Its exceptional flexibility facilitates mounting on circular and oval connectors.

Perfect for applications requiring thermal and acoustic insulation, SONOFLEX combines lightweight properties, mechanical strength, and advanced technical performance for optimal air quality.

The ISOFLEX insulated flexible duct features a multi-layer aluminum-polyester inner core with 25mm thick glass wool insulation (16 kg/m³) and an aluminum-laminated polyester outer jacket. Its exceptional flexibility ensures easy installation on both circular and oval connectors.

Perfect for ventilation and air conditioning systems requiring high mechanical strength and thermal efficiency. Operating temperature range from -30°C to +120°C with M1 fire resistance rating (no toxic gas emissions).

Available in diameters from 82mm to 508mm, supporting maximum pressure of 2500 Pa and air velocity up to 30 m/s. Supplied in standard 10m lengths, compressed in reinforced cardboard packaging.

Aluminium flexible duct ALUFLEX is a lightweight non-insulated air duct made of multilayer polyester laminated aluminium foil reinforced with spiral high tension steel wire. Its exceptional flexibility allows for easy installation on round and oval connections.

Designed for ventilation and air conditioning systems with low and medium air pressure where high mechanical strength is required. Its multilayer aluminium-polyester structure with steel wire ensures durability and performance.

Technical specifications: temperature range from -30°C to +130°C, maximum air velocity of 30 m/s and operating pressure up to 2300 Pa. Available in diameters from 80 to 500 mm, in standard length of 10 m.
