your filtration’s support

CleanAir is a manufacturing branch of Defim and specialises in the production of filter sleeve supports for industrial dust filtration. Constant research and investment are geared to creating a highly specialised and flexible structure to provide consultancy, products and services for the field of air filtration and separation.
CleanAir’s primary objective is the creation of a production process which is entirely managed within the firm, so as to retain full control and full responsibility over every stage of production and the consequent product quality.
In pursuit of this objective, CleanAir has production lines which are entirely designed and built in-house, with completely automated machinery which can manufacture any type of filter sleeve support.

To ensure a constant quality standard, CleanAir has achieved ISO 9001: 2015 certification for the ‘Manufacture of filter bag cages for industrial filtration according to customer specifications’.

40 years of experience

Clean Air is the result of more than forty years of operation and experience, always geared to research and the creation of new technological solutions.
The quest for constant improvement, not just in the product but also in the production process, means that Clean Air is today in a position to respond effectively to a wide range of criteria in terms of quantity, quality and timings.

Quality, but also flexibility and speed: Clean Air has fine-tuned its production lines to respond to large and small demands, and years of research enable us to offer products like the Eco HPC cages, but also less sophisticated alternatives.
