Retentions of standard screens are calculated according to international standards by means of perfectly round spheres. Our screens are only one layer and therefore they cannot be considered the same as conventional filters. Each screen gasket has a high-performance gasket made out of one of the validated compounds that we use for our standard Sanitary Gaskets range.

Applications

Screen Gasket molded our standard

In many upstream and downstream processes, it is sometimes required to do an inline or in situ filtration step. It is usually meant to capture isolated particles created by moving parts in the system. Deterioration of valve membranes, pumps or gaskets can generate these kinds of particles.
In a start-up phase, it can be used to protect pumps from large items that accidentally fall in the system and are flushed through causing major damage.
Filling needles can be equipped with a fine filter down to 10μm to capture anything that should not be there before the vial is sealed.

Double Mesh Screen Gaskets

Fine mesh screens are fragile and could break away when solid material builds up . It is possible to use two screens on top of each other, one for support and one for the final filtration. When using double mesh screens it is important to place them in the correct orientation towards the flow direction. Reversed in process conditions could lead to failure of the fine mesh by braking off.

When entering the area of finer mesh sizes that a better solution is we recommend the use of Sintered mesh screens. The screen is build up with a supporting screen and a fine mesh screen on top. These are "welded" together and cannot be separated. This Double mesh product provides better pressure resistance and is suitable for backwashing cycles.

Sock Screen Gaskets

Sock screens are designed to take up a large amount of soil that it offer a greater soil collection capacity than standard flat screens. Flat screens will finally block when too much soil is accumulated. There is also a potential chance that the flat screen can break. Sock screens can take 8 to 10 times more soil, They are available in 150 mm (6") and 50 mm (2") lengths. If the capacity of a standard flat in situ filters is not sufficient then the Sock Screen is a good alternative, therefore it be used in processes where high particle collection is expected.

Perforated Screen Gaskets

DIN 11864 screen

We have introduced a complete range of DIN11864 screens. The DIN11864 is becoming more popular in both the pharmaceutical and the food industries. The Tri-Clamp fitting has been around so long that all special components have become easily available. The DIN11864 is a relatively new fitting and therefore these special components are not readily available. They are available now at Komo because we made an effort to invest in these new components.

The Newest: Screen Gaskets With Tab

How useful would it be if you can see which screen gasket is mounted by looking only on the outside of your piping system? You do not have to disassemble anything and you do not have to memorize it. Our screens gaskets are meant to capture isolated particles created by moving parts in our piping system. On top of that, our engineering has developed screen gaskets with tabs. A tab is a helpful feature to visualize the presence of our screen gaskets in line and is easy to recognize from the outside.


As you can see in both photos, the mesh size and heat number screen material can be laser engraved on the tab. Our screens are available in various mesh sizes and compounds.
