Ventilation duct flat 220×90 mm connector with non-return valve

With this duct connector you can connect two flat ducts (220 x 90 mm) to each other. A non-return valve has been integrated in the connector. This prevents cold air from flowing through when the ventilation is switched off. It is easy to install and can be made airtight by means of tape.

The duct connector is white and made of lightweight plastic. It has a smooth inside to minimise air resistance.
