Flexible air duct ALSD-3

polyesterthermally-insulatedfor fire protection

The Sonouct AD-3 is identical in design to the AD-L, except for the inner cladding. The outer cladding is a duct resistant to the maximum temperature of 250˚C; this makes it perfect for fireplace hot air distribution systems and for all ventilation systems with a maximum air temperature of 250˚C. Packaging: 10 metre sections compressed to 1200 mm and packed in cardboard boxes, and 5 metre sections compressed to 600 mm and packed in cardboard boxes. Flexibility (winding diameter): Depends on the actual duct outer diameter, i.e. ca. 0.80D (mm). Temperature range: -30˚C to +250˚C Maximum acceptable vacuum: Depending on the duct routing. For straight runs, 1/3 of the pressure transferred at the specific diameter can be taken.
