AIRDUC® PUR 350 AS TWIN COLOR – Customised and innovative

NORRES Group expands the AIRDUC® TWIN COLOR series

The NORRES Group has now expanded its TWIN COLOR product series with the AIRDUC® PUR 350 AS TWIN COLOR. This is the second hose in the AIRDUC® series that can be coloured in two colours in any desired combination.



Following on from the AIRDUC® PUR 355 AS TWIN COLOR, the NORRES Group’s product range has now been expanded with the AIRDUC® PUR 350 AS TWIN COLOR. The idea behind the TWIN COLOR hoses is as simple as it is convincing: quality products are coloured according to each customer’s requirements. Any combination of colours is possible. The option of colouring the hose in two specific colours adds significant value: each hose can be customised and adapted to the client’s corporate colours on request, ensuring that the corporate design is consistently applied. As a result of this, a higher quality and more professional appearance is achieved for the hose as a machine component and hence for the entire product during use. What’s more, the combination of colours for the AIRDUC® PUR 350 AS TWIN COLOR can be varied according to the intended use or field of application. Any colour combination is possible.
