– TheV-shaped pleating method guarantees an optimum geometry of the pleats and a uniform distance between them,

resulting in a lower pressure loss with a higher airflow.

– V-shaped pleating technology allows us to remove the aluminium separators and thereby eliminate the risk of

leaks due to the perforations of the aluminium separators.

– The filter is light and easy to eliminate thanks to the new manufacturing technology.

– The total use of the filtering area, in addition to the uniform dust deposition achieved through the new pleat shape

technology, leads to longer duration.

– Due to the increased filtering area, the speed of the air through the filter and the resistance to flow decrease, resulting in energy saving.

– Thanks to the uniform shape of the pleats the airflow does not generate turbulences.

– The Microven filters provide more protection and reliability as a result of the larger filtration area achieved by the new pleating

shape technology. Also filtration efficiency is improved and the cost-efficiency ratio is excellent.

– The filter media is self-extinguishing glass microfiber paper (class F-1) and resistant to humidity up to 100% relative humidity.
