About SMK

SMK Filtration

Innovative Filtration System

for Zero Waste Oil and Waste Liquid

Using our unique filtration technology, machining fluids and hydraulic oils used

in various machines are kept constantly clean, solving cost and quality issues on-site at once.

Micro sludge can also

be filtered at high speed

in a single pass.

Special filter paper, developed with SMK's long-cultivated filtration technology, achieves ultra-precision filtration. Micro sludge generated during carbide grinding can also be filtered quickly in a single pass. This sludge-free process improves quality and brings various benefits, such as extending the lifespan of equipment and coolant.

Creating a clean

environment with

integrated case filters

By integrating the case and filter into a single structure, filter replacement efficiency is greatly improved, reducing downtime. The adoption of the Double-Coupler system prevents liquid splashes and eliminates sludge cleaning and other maintenance, keeping the worksite clean.

SMK Filtration:

Solving Various

Business Challenges

Our solutions go beyond simply filtering machining fluids and hydraulic oils; they improve work efficiency, enhance workplace environments, increase machining accuracy, and reduce environmental impact, addressing various bussiness challenges.
