Filter sheets:
A filter sheet is a depth filter which uses a 3D matrix. Filter sheets are made of cellose due to the special production method a 3D matrix is created in a filter sheet. This 3D matrix ensures that filter sheet not only filter the particles, but also absorb them and this ensures that there is much more chance that the dirt stays behind in the filter sheets. 

Filter sheetss (depth filters) are often used in applications with a high percentage of contamination where surface filters do not give enough filter life. Our filter sheets have a thickness of 3 to 4 mm, which is 3.000 to 4.000 times the size of a 1 micron particle.

We have a large variety of filter sheets, suitable for many applications from coarse filtration to sterile filtration.
