Why cellulose fibers make better filters than synthetics

The CJC Filter has been removed from service after a recommended period an is saturated with varnish. The filter has done its job.

Regarding oil filters on wind turbine gearboxes, ask yourself:

Answer: Because the foundation of the entire industry is sustainability.

C.C.JENSEN A/S says it has been using sustainable materials for 63 years, long before wind turbines became an option for providing green energy. Natural organic sustainable fibers are nature’s best with properties superior to those of synthetic fibers. C.C.JENSEN figured out how to use cellulose fibers to provide the best depth-filtration media.

First of all, natural cellulose fibers come in many sizes and shapes. To make the best filters, the company mixes and treats raw fibers before making the company’s unique composition and design, which is comprised of only cellulose filter material. It contains no steel, plastic, or chemicals. The mix of fibers and the density of the filter insert provide efficiency in terms of not only the filtration degree but also the capacity of the filter insert.

This means that original CJC Filter Inserts have specific properties depending on the actual requirements of the application and the oil to be filtered. The filter inserts made for today and for tomorrow for wind turbine gearboxes are designed for this application only and the operating conditions of the bearings, gears and lubricants. The CJC Filter Inserts made this way retain particles in the pockets between the fibers while the fibers also act as a media to absorb moisture and varnish.

Due to the way in which the inserts are produced, users will notice an almost infinite number of layers within the filter. Thus, any reference to surface area from our side would exceed that of any other filter type.

The fibers also come with a polar charge, enabling a polar attraction between the particles and fibers. Synthetic fibers do not share these properties. All the features of our filter inserts are provided for by nature. No chemicals or artificial compounds are necessary. Why would you ever consider using synthetic fibers containing energy-intensive materials, such as aluminum or steel, or adding chemical compounds, negating the intention of the whole industry?
