DEPTH FILTER CARTRIDGES

The effectiveness of a filtering cycles depends on the time for which the fluid remains in contact with the filtering material. The structure of a filter cartridge can be compared to a filtering bed with a considerable volume and depth, composed of a three-dimensional labyrinth of extremely fine channels con- nected together. 75% of the volume of a cartridge is empty to allow for a high impure-particle capturing capacity.

The Principle

Oil flows through the cartridge in a radial manner, from the outside to the in- side. Even the smallest contaminating particles deposits within the cartridge thanks to the long route covered by fluid as it travels through the filtering ma- terial. The degree of filtration is guaranteed to be ≤ 3 μm.

Additives

TEC95 cartridges are made of natural fibre that does not interact chemically with oil and that does not hold back the additives.

Cartridges with a great volume and depth to offer effective filtering

The TEC95 filter cartridges fitted in our fine filtering systems have an absorp- tion with a degree of filtration of ≤ 3 μm. Research conducted by independent scientific institutes (e.g. RWTH Aachen and TÜV Essen) have demonstrated that TEC 95 filter cartridges guarantee oil with an exceptional level of purity, therefore fulfilling the provisions of the ISO 4406 (up to code 10/3) and NAS 1638 (up to Class 1) standards. TEC95 cartridges are made of natural fibre that offers enormous advantages if compared to other filtering materials.
