ROKITECHNO | Filter cartridge & Filter system

Among the converting technologies in the electronics industry in recent years, the significance of the filtration technology is being highlighted. The filtration is certainly one of the techniques which improve the quality of surface coating. ROKI TECHNO helps customers have the ideal surface coating with our separation technology.

Figure 2: Coating without using filter

If the surface is coated without using a filter, aggregations are made on the surface and, therefore, the surface is not coated evenly (Figure 2). Meanwhile, if the filter which is adequate for the problem is used, the surface is even (Figure 3).

One of the techniques for having desirable surface coating is the filtration. ROKI TECHNO proposes filter cartridges which areoptimal for customer’s applications and problems.

1)If you want to separate fillers from aggregations and foreign substances.	SHP SLS
2)If you want to remove all foreign substances and coat the surface with a sub micron class film.	SHP CTX MGA
3)There is no substance to be removed, but you want to trap just in case.	MPX
4)You want to remove foreign substances from highly viscous liquid.	HC MPH

The Ez-Change series is the type of filters which can be changed by one-touch without exposing the liquid. The Ez-Change XS type which minimizes liquid loss according to the application is also available.
