SONO flexible ducting, 250 mm diameter

Product detailed description

The sound-insulated flexible SONO air duct 254 mm, for 250 mm diameter, has a similar internal structure to ALU, but is supplemented with sound insulation from a 25 mm layer of mineral wool. The inner duct is perforated like a noise silencer.

Extracting and supplying fresh air is very important for every growing space, and the flexible SONO duct allows you to extract air simply and reliably at a favourable price. Thanks to its flexibility, the duct can be attached wherever it is necessary to avoid obstacles along the way. 

Features and benefits:
- temperature range is -30°C to 140°C
- maximum pressure is 2000 Pa
- suitable for both extract and intake air
- universal use
- the duct can be fitted onto all standard flanges of its diameter (the actual diameter is several mm larger precisely so that this is possible)

The SONO duct is suitable for connecting fans or carbon filters with a diameter of 250 mm.
If you are looking for an ordinary, easily shapeable and uninsulated duct, choose ALU.
If you need higher durability, we offer COMBI, which is in effect Aluflex wrapped in plastic.

Recommended accessories:
- clamping strap - for attaching the duct to the flange
- 250 mm fans
- 250 mm odour filters
- protective mesh for the outlet of 250 mm ventilation ducting

TIP! Do not create unnecessarily sharp bends, as this will increase air resistance as it passes through the ducting. More information in our article.
